Death, Grief, & Purpose from a Longevity Science Perspective | 80 Nov 14, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Grief: one of the most profound emotions humanity shares; a universal experience that transcends time, culture, and place; a phenomenon as ancient as human existence. Grief is as intrinsic to the human experience as joy or hope, and no one escapes it—to grieve is to be human. In this episode, Matt and Nick discuss their recent personal experiences with grief and loss. Matt lost his German Shepherd Dobby to degenerative myelopathy, while Nick's father succumbed to health issues precipitated by heavy alcohol use. Together they explore how grief affects mental and physical health, including how it affects the four Pillars of Healthspan—Eat, Sleep, Move, and Connect—as well as the hallmarks of aging. They also discuss the tricky emotions that can accompany grief, the different ways people react to change, and the unanticipated positives of negative experiences.

We are Keeping People Sick Longer - We Need Medicine 4.0 | 78 Nov 05, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episode: Defining "Healthspan" & its role in LIVING LONGER: https://www.youtube.com/watch?v=cI6CNFeBl88 Author and physician Peter Attia popularized the concept of "Medicine 3.0", the third in a series of distinct phases—Medicine 1.0 and Medicine 2.0 included—that describe the evolution of medicine as we know it. In this episode, Matt takes us through these phases and proposes a "Medicine 4.0" as the best next step beyond Peter's Medicine 3.0. He discusses the reactive disease care approach of Medicine 2.0, noting that while it has done a stellar of job of increasing life expectancy through developments such as widespread antibiotic use, sanitation improvements, and childhood mortality reductions, it has not been quite as useful at improving healthspan. People may stay alive for longer than they used to, but many of them spend this extra time alive suffering from at least one significant chronic disease or disability that significantly impedes their vitality and quality of life. Matt suggests several approaches we should take to kick off Medicine 4.0 and also presents an even longer-range version of the future: Medicine 5.0.

The Probability of Us Living to Be Much Older? | 77 Oct 31, 2024

Subscribe to our channel: https://www.youtube.com/@optispan How much longer might humans live? This question has fascinated scientists, philosophers, and dreamers for centuries. The average human lifespan has already increased dramatically over the past hundred years thanks to advances in medicine, public health, and technology, and the prospect of radically extending human life remains one of humanity’s most compelling frontiers. A recent paper published in the scientific journal Nature Aging argues that radical life extension is unlikely to happen in the 21st century. The paper has sparked fascinating conversation in the longevity industry around topics such as realistic deliverables for the field, the predictive value of past technological trajectories, the reasons behind lifespan decreases in the western world, incremental versus bold research goals, and where we should go from here. Matt and Nick discuss the paper and provide their own take on the prospect of radical life extension and what we can realistically expect to see in the coming decades.

Metformin is an FDA-approved prescription medication commonly used to treat type 2 diabetes by improving insulin sensitivity and decreasing the amount of glucose produced by the liver. After examining the influence of metformin supplementation on a suite of physiological, imaging, histological, transcriptomic, and RNA sequencing parameters, the paper's authors concluded that metformin exerts geroprotective effects on various tissues. Matt and Nick spend this episode dissecting the paper, highlighting potential improvements to study design and presentation, and discussing the use of metformin as a longevity drug.

Does Plant Protein Slow Your Aging? | 69 - Longevity This Week #12 Oct 03, 2024

Subscribe to our channel: https://www.youtube.com/@optispan We recently came across a study published in the European Journal of Nutrition that examined the relationship between plant and animal protein intake and measures of biological aging. The study, which uses data from the UK Biobank, a long-term database of biological data from half a million participants in the United Kingdom, found that a higher plant protein intake correlates inversely with biological aging. Matt takes us through the study and gives us his take on the results and potential explanations for them as well as on the validity of the biological age measures used, the complexities of nutrition research, and core principles of healthy eating.

The Dog Aging Project that aims at Helping Dogs Live Longer | 68 - DAP #2 Sep 26, 2024

Subscribe to our channel: https://www.youtube.com/@optispan More about the Dog Aging Project: https://dogagingproject.org/ The Dog Aging Institute: https://dogaginginstitute.org Enroll your dog in the Dog Aging Project: https://redcap.dogagingproject.org/surveys/?s=DYYDHK8HAP We get lots of feedback and questions about the Dog Aging Project (DAP) from viewers, so we wanted to provide an update about how the project is going as well as some context. In this episode, Matt dives into the project's winding 10-year history, which includes navigating the vagaries of government funding, handling skepticism from fellow academics, and managing clinical trial enrollment in the midst of a global pandemic. He provides a candid peek into the logistical coordination, interdisciplinary collaboration, and leadership required to run a large-scale, ambitious scientific project such as the DAP, and the necessity of articulating clear and compelling goals that can rally support from both the scientific community and funding bodies. The DAP is a study of canine health and longevity aimed at understanding how dogs—and, eventually, humans—age. The project has two broad goals: to help us understand the biology of aging, and to enable us to do something about it.

This Study Says IL-11 Inhibitor Drug May Extend Lifespan | 64 - LTW #11 Sep 12, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Check out the paper: https://www.nature.com/articles/s41586-024-07701-9.pdf Related episodes: The Benefits of Protein Restriction, How Protein Affects Hormones & FGF21: https://youtu.be/Nf1GhkAFiWY A recent paper demonstrating that injecting older mice with an anti-IL-11 drug extended their median lifespan made a splash in the geroscience community this summer. IL-11 is a proinflammatory cytokine that plays a role in regulating various biological processes, including hematopoiesis (the production of blood cells), bone health and remodeling, and tissue repair. Meanwhile, cytokines act as messengers between cells, helping to regulate immune responses, inflammation, and the production of blood cells. In excess or when dysregulated, cytokines can contribute to chronic inflammation and autoimmune diseases. In this episode, Matt discusses the role IL-11 plays in the body, the ERK, AMPK, and mTOR pathways, genetic and pharmacological models of IL-11 reduction, and more. He goes over the paper's claims and provides his take on whether this finding is a game-changer in the longevity field as well as on what further questions he'd like to see answered in follow-up studies.

Matt shares his professional history with David, including his early interactions with David in Leonard Guarente's lab at the Massachusetts Institute of Technology (MIT) and scientific differences that emerged after Matt and colleagues were unable to reproduce a key result from David's work pertaining to resveratrol. Their discussion touches on some of David's scientific claims about age reversal, the role of institutions such as Harvard University in regulating scientific integrity, the potential for future interventions in healthspan and longevity, and the importance of separating personal feelings from scientific evaluation. David, currently a professor in Harvard Medical School's Department of Genetics at the Paul F. Glenn Center for Biology of Aging Research, is a prominent geroscience researcher whose lab focuses on age-related epigenetic change, cellular reprograming, longevity drug discovery, mitochondrial fitness, reproductive aging, neurodegenerative disease, and the human secretome. He has received awards including the National Institutes of Health Nathan Shock Award, the Merck Prize, and the Australian Medical Research Medal, and was elected to TIME's 2014 “100 Most Influential People in the World" list. David conducted postdoctoral research at MIT and obtained a PhD in Molecular Genetics at the University of New South Wales.

Does NMN Actually Increase VO2 MAX? | 61 - Longevity This Week #9 Sep 03, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: Scientists Debate How to Live Longer & Longevity Drugs: https://youtu.be/EebH_taOlAA Supplement Industry Secrets: What They Aren't Telling You About NAD+ & NMN" https://youtu.be/OgsfIUfuyqk NAD+ boosters are supplements designed to enhance levels of nicotinamide adenine dinucleotide (NAD+), a central coenzyme found in all living cells and involved in innumerable biochemical reactions that include DNA repair, glycolysis, stress responses, and more. As we age, NAD+ levels naturally decline. Supplements containing NAD+ precursors such as nicotinamide riboside (NR) or nicotinamide mononucleotide (NMN) aim to counteract this decline by providing the body with the building blocks it needs to restore NAD+ levels. Proponents of these supplements suggest that they may support better energy metabolism, improved cognitive function, and even promote longevity. However, while early research is promising, it's important to approach these supplements with caution and consult healthcare professionals to understand their potential benefits and limitations. For this episode, we examined a 2022 study that looked at the effects of NMN supplementation on VO2 max, or the maximum amount of oxygen a person can use during intense exercise, in amateur runners. Matt and Nick review the study, discuss its limitations, and provide their takes on whether NMN actually improves endurance and aerobic capacity during exercise—and thus whether we should take the claims of NMN supplement sellers seriously.

Scientist Reacts to Greg Doucette's Controversial Take on DEXA Scans | 57 - Longevity Reacts #4 Aug 13, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: Why DEXA Scans Are NOT the HOLY GRAIL of BODYFAT Testing - Science Explained: https://www.youtube.com/watch?v=2Gg4Jm5KS1Y Are DEXA scans ACCURATE? What YOU NEED to KNOW: https://youtu.be/SsDJZMlM1ko The UNEXPECTED Ozempic Weight Loss Body Scan Results (DEXA): https://youtu.be/C_Z7qPVRA5M Coach, bodybuilder, and powerlifter Greg Doucette published a video on his Youtube channel discussing what he sees as the shortcomings of DEXA scans and why DEXA scans are not, in his opinion, the gold standard of body composition measurement. He bases his views on personal experience as well as his interpretation of a 2019 study that examined how closely DEXA and MRI measurements correlate. In this episode, Matt reacts to Greg's video and presents his own opinion about the validity of DEXA scan measurements. Together with Nick, he discusses what DEXA scans do and don't measure, potential sources of inaccuracy in DEXA scans, honest interpretations of scientific literature, and more. A DEXA (dual-energy X-ray absorptiometry) scan is an advanced imaging procedure for measuring bone density and composition. DEXA scans utilize two different energy levels of low-dose X-ray beams—one absorbed mostly by soft tissue, and the other absorbed mainly by bone—to differentiate between bone, fat, and lean tissue. In so doing, they provide noninvasive and detailed information about bone health, risk of osteoporosis or fractures, and body composition. While medical practitioners typically perform DEXA scans on the lower spine and hips, they can also perform DEXA scans on the whole body for the purposes of early detection and intervention.

Research on aging genes not only deepens our understanding of the biological aging process, but also opens up potential avenues for developing therapies aimed at extending healthy human lifespan. By targeting these genes, scientists hope to delay the onset of age-related diseases such as Alzheimer's disease, cardiovascular disease, and cancer, ultimately promoting a longer and healthier life. In this episode, Matt discusses several ways we can identify and categorize aging genes. He talks about how genes can serve as predictive signatures of chronological or biological age, potential conserved genetic regulators of longevity, and how unbiased genetic screens can still be biased. He also provides his unique perspective on aging genes in humans and the potential to optimize longevity through genetic modulation.

The Benefits of Protein Restriction, How Protein Affects Hormones & FGF21 | 52 - Cristal Hill Jul 25, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Check out Cristal's page at USC: https://gero.usc.edu/faculty/cristal-m-hill-phd/ Matt recently attended the 52nd annual meeting of the American Aging Association in Madison, Wisconsin and met with several people doing fascinating work in or adjacent to the geroscience field. One of these was Cristal Hill. Cristal is an Assistant Professor of Gerontology at the University of Southern California Leonard Davis School of Gerontology, where she runs a lab focused on how dietary protein might affect adipose tissue (body fat) function, metabolic, and endocrine health during aging. Cristal received postdoctoral training at the Pennington Biomedical Research Center of Louisiana State University, a PhD in molecular biology from Southern Illinois University, and a B.S. in Animal Sciences from Tuskegee University. In this episode, Matt and Cristal discuss fibroblast growth factor 21 (FGF21), a hormone produced mainly in the liver that helps regulate metabolism and control how the body uses sugar and fat for energy. They also chat about FGF21's influence on food preferences, role in healthy aging and longevity, potential as an obesity treatment, and more, as well as the broader impact of protein restriction on health- and lifespan as we age. Some definitions: the term "wildtype" refers to the typical form of an organism or gene as it occurs in nature, and represents the standard or normal genetic makeup and phenotype against which mutants or genetically modified organisms are compared. A "knockout" is an organism in which a specific gene has been completely disabled or "knocked out" to study the gene's function by observing the differences between the knockout organism and a wildtype one. Finally, a "transgenic" organism is one that has had a gene or genes introduced into its DNA to give the organism new traits or abilities, such as resistance to diseases, or to study the effects of the introduced gene.

Longevity Scientist Reacts to Bryan Johnson's "I Edited My DNA To Live Forever" |50-Longevity Reacts Jul 18, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Check out the Bryan Johnson video: https://www.youtube.com/watch?v=bax8to_s07Q Last month, entrepreneur and venture capitalist Bryan Johnson released a Youtube video detailing his trip to Prospera, Honduras to receive follistatin gene therapy from the Minicircle Gene Therapy clinic. Bryan describes Minicircle's gene therapy as "a pioneering technology with the potential to improve muscle and strength, slow the speed of aging, and many more benefits". In this episode, Matt reacts in real time to his first watch of Bryan's video and responds to Nick's questions about various topics that come up along the way. He provides a primer on gene therapy and its potential as a longevity intervention, discusses the clinical evidence for follistatin's effects on humans and model organisms, and goes through several things one might want to consider when deciding whether to partake in a new therapy. He also gives his honest take on "offshore medicine"—medicine performed in countries that lack the regulatory oversight of the United States Food and Drug Administration—and discusses potential mechanisms for safely offering experimental therapies in the United States. Follistatin is a glycoprotein that functions as a potent inhibitor of several members of the TGF-beta superfamily, particularly activin and myostatin. It is involved in various physiological processes, including muscle growth and development, reproduction, and inflammation. By binding to these proteins, follistatin prevents them from interacting with their receptors, thereby regulating their activity.

The group included assistant and tenured professors at various institutions around the United States, startup founders, and prospective PhD students with geroscience research interests that span the microbiome, mitochondrial dysfunction, frailty, metabolism, sex differences in aging, and more. In this episode, Matt and his former lab members pool their collective knowledge to engage in a lively conversation (and sometimes debate) about longevity interventions such as metformin, acarbose, and sauna use. In their discussion, they touch on hot-off-the-press positive results, unpublished data, and planned research from their respective research groups and labs. They also bring up nuances to recent published work, including results from the Interventions Testing Program on various interventions that Matt discussed in a previous podcast episode.

Why Drinking a Banana Smoothie IS the Same as Eating a Banana | 44 - Longevity this Week #8 Jun 27, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Should you add bananas to your smoothies? No, according to someone on TikTok who posted a viral video suggesting that our smoothies should be banana-free. On the basis of a 2023 scientific journal article, this TikTok user asserted that bananas destroy the beneficial polyphenols found in other fruits and vegetables that might be in your smoothie. As is often the case with science, there's more to this story than the punchline. In this episode, Matt puts a magnifying glass to the 2023 journal article to figure out what the study actually showed, and whether we do, in fact, need to be careful about adding bananas to our smoothies.

Solving the "Lack" of Anti-aging Discovery & Ranking Current Interventions | 42 - Mark McCormick Jun 18, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: Reversing Biological Age: Have we finally found the answer?: https://youtu.be/ivP3QTyQ2d4 Matt recently attended the 52nd annual meeting of the American Aging Association in Madison, Wisconsin and met with several people doing fascinating work in the longevity field. One of these was Mark McCormick, an Assistant Professor at the University of New Mexico (UNM) Department of Biochemistry and Molecular Biology. At UNM, Mark runs a lab that investigates age-delaying drug targets, develops machine learning tools for studying aging, and identifies conserved aging mechanisms and pathways in model organisms and humans. Mark previously completed a postdoc with Brian Kennedy at the Buck Institute for Research on Aging, a PhD in Biochemistry and Molecular Biology with Cynthia Kenyon at the University of California, San Francisco, and a B.S. in Mechanical Engineering as well as a B.S. in Biology from the University of Texas at Austin. In this episode, Matt and Mark chat about aminoacyl-tRNA synthetases, a group of enzymes that play an essential role in protein synthesis. They discuss the promise and risks of tRNA synthetase inhibitors to treat diseases of aging and extend life- and healthspan (spoiler: don't take tRNA synthetase inhibitors yet). They also talk about why Mark's lab has held off on doing mouse experiments thus far, the challenges of proving causality in longevity experiments, interventions about which Mark is optimistic (or not), and more.

The UNEXPECTED Ozempic Weight Loss Body Scan Results (DEXA) | 41 - HSM #8 Jun 13, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: The Importance of Body Composition & Ways YOU can measure it | 21 - HSM #3: https://youtu.be/gM3aYTMsqNI We brought George Sutphin back on the podcast to bare his soul—or at least his DEXA scan and VO2 max test results. A DEXA (dual-energy X-ray absorptiometry) scan is an advanced imaging procedure for measuring bone density and composition. DEXA scans utilize two different energy levels of low-dose X-ray beams—one absorbed mostly by soft tissue, and the other absorbed mainly by bone—to differentiate between bone, fat, and lean tissue. In so doing, they provide noninvasive and detailed information about bone health, risk of osteoporosis or fractures, and body composition. While medical practioners typically perform DEXA scans on the lower spine and hips, they can also perform DEXA scans on the whole body for the purposes of early detection and intervention. A VO2 max test measures the maximum volume of oxygen an individual can utilize during high-intensity exercise. At its core, it provides an assessment of a person's cardiovascular fitness and aerobic endurance. During the test, the subject performs a graded exercise protocol, typically on a treadmill or stationary bike, while wearing a mask connected to a metabolic cart. The cart measures the volume and gas concentrations of inhaled and exhaled air. As the exercise intensity increases, the test measures the point at which oxygen consumption plateaus, despite further increases in workload. This point is the VO2 max, indicating the person's aerobic capacity and endurance potential. The results can provide valuable information for athletes to tailor their training programs, for clinicians to assess the efficacy of treatments, and for researchers studying the effects of various interventions on cardiovascular health. VO2 max levels are strongly correlated with all-cause mortality. In this episode, we chat with George about how he changed his readouts with time, whether his body composition tracks his work deadlines, his experiences with Ozempic, and more. University of Arizona Assistant Professor of Molecular and Cellular Biology George Sutphin runs a lab that investigates genetic determinants of longevity, the effects of kynurenine-based interventions on lifespan, and environmental regulators of the aging process. George, who was an aerospace engineer before he discovered the promise of geroscience, completed his PhD at the University of Washington and worked as a postdoctoral associate at the Jackson Laboratory prior to his current faculty position. He currently serves as Chairperson of the American Aging Association.

The Two New Highest Ranked Compounds For Lifespan Extension According to the ITP | 40 - LTW #7 Jun 11, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: These 14 Medications are linked to lower death rates in humans: https://youtu.be/Ju1p_L-2Bq4 DON'T Take Resveratrol Until You Watch This Video: https://youtu.be/MmIBdqsQYfw How do scientists decide which interventions are worth testing in humans for potential health- and/or lifespan benefits? One way to start is to examine how interventions perform in model organisms such as mice. The Interventions Testing Program (ITP), a federally-funded initiative that began in 2002, tests drugs that may delay mouse aging, with the hope of eventually identifying new longevity interventions for humans. The program aims to take an unbiased approach to interventions testing as possible and to make all data publicly available. In this episode, Matt goes over recent ITP tests of a broad range of interventions that includes a vasodilator, a beta-blocker, a drug to reverse cyanide poisoning, and more. The drugs are alpha-ketoglutarate, 2,4-dinitrophenol, hydralazine, nebivolol, 16α-hydroxyestriol, sodium thiosulfate, and canagliflozin. He discusses which of these interventions produces lifespan benefits in mice, gender differences in effects, results from previous studies of the interventions, and the importance of examining the life expectancy of controls when evaluating the results of lifespan experiments. Matt has served on the ITP steering committee since 2012.

(PART 1): https://youtu.be/-ujIfZXGbDA George Sutphin is back! So many of you enjoyed Matt's interview with him back in March 2024 about 3HAA and NAD+ that we decided to bring him on the podcast once again to chat about the potential effects of oral NMN supplementation. You may have heard of over-the-counter supplements aimed at boosting nicotinamide adenine dinucleotide (NAD+) levels. Underlying these supplements is the hypothesis that levels of NAD+, a central coenzyme found in all living cells and involved in innumerable biochemical reactions that include DNA repair, glycolysis, stress responses, and more, decrease with age. The decrease may be associated with aging and age-related disease, and restoring NAD+ levels via supplementation is therefore likely to increase health- and/or lifespan. In this episode, Matt and George examine a recent finding that oral supplementation of NAD+ boosters increases molecular signatures that indicate kidney damage. They discuss the NAD+ signaling pathway, models for how NAD+ might drive kidney damage, how they would expand upon the study for further research, and more. University of Arizona Assistant Professor of Molecular and Cellular Biology George Sutphin runs a lab that investigates genetic determinants of longevity, the effects of kynurenine-based interventions on lifespan, and environmental regulators of the aging process. George, who was an aerospace engineer before he discovered the promise of geroscience, completed his PhD at the University of Washington and worked as a postdoctoral associate at the Jackson Laboratory prior to his current faculty position.

The Dog Aging Institute: dogaginginstitute.org Save the Dog Aging Project! In 2014, Matt co-founded the Dog Aging Project, an ambitious, large-scale study of canine health and longevity aimed at understanding how dogs—and, eventually, humans—age. The project has two broad goals: to help us understand the biology of aging, and to enable us to do something about it. A third goal that often goes unmentioned, but is (to some) no less important, is to give us more time with furry friends who often become part of the family. Dogs are some of the best animals we can use to study longevity. While many of the model organisms such as yeast, worms, mice, and rats that we commonly use to study aging have certainly helped us unearth interesting insights, they typically live in highly controlled laboratory conditions that do not replicate the diverse environmental factors that humans experience. Researchers also often use inbred strains of these animals due to their genetic uniformity, a practice that offers experimental advantages but also introduces issues such as limited generalizability and undetected gene-environment interactions. Meanwhile, dogs share our environments in every way, develop the same age-related diseases as do humans, exhibit high genetic diversity, and age rapidly enough that we do not have to wait decades to observe the effects of interventions on dog life- and healthspan. The Dog Aging Project has grown to become the world's largest study of aging. Over 50,000 dogs are currently enrolled in the project, enabling researchers to create an immense dataset comprising over 36 million data points and a biobank containing more than 10,000 samples that will be invaluable to helping us answer key questions about the biology of aging. Data from the project has contributed to the publication of over 50 peer-reviewed scientific papers. As this is a citizen science project that harnesses the collective power of volunteers to contribute to scientific research, the Dog Aging Project will make all data publicly available free of charge to academics and nonprofit institutions to facilitate the blooming of as much useful research as possible. The Dog Aging Project needs your help. Federal funding to the project has recently been withdrawn, and the project needs financial backing to support its veterinary and computational infrastructure as well as to complete a clinical trial of rapamycin in dogs. The project hopes to decrease its reliance on federal funding and thus hopes to encourage philanthropic funding as far possible. Top donors stand to receive a full Optispan Trailblazer concierge clinic experience and lunch with Matt, and other donors may receive Optispan swag. Every contribution, no matter the size, makes a difference. We hope you will consider donating!

Is This The Best Time to Work Out? | 36 - Longevity This Week #6 May 28, 2024

Subscribe to our channel: https://www.youtube.com/@optispan In this episode, we discuss three findings that have made the rounds in the geroscience and healthspan spaces in recent months. They relate to three universally-relevant topics: pregnancy, exercise, and diet. The first study suggested that women who have been pregnant at least once age faster than women who had never been pregnant, controlling for social, environmental, and genetic variation and measuring aging rate via six epigenetic clocks. The second study found a connection between workout timing and cardiovascular disease, microvascular disease, and all-cause mortality risk in adults with obesity. Evening workouts appeared to lead to the greatest morbidity and mortality benefits. The third study, which researchers presented at a recent American Heart Association meeting, demonstrated a positive relationship between time-restricted eating—that is, eating all daily meals in a short time window rather than throughout the day—and risk of dying from heart disease. It's been an interesting time for geroscience-related findings. Matt and Nick chat about the three studies, discussing their potential limitations, possible mechanisms underlying the observed longevity effects, and further work that would provide greater depth to our understanding of healthspan and longevity.

The Surprising Way Body Size Relates to Lifespan | 35 - Longevity Science #7 May 23, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Is bigger always better? It depends. Throughout the human lifespan, body size plays an important role in determining health outcomes and quality of life. It's not just about body mass index, fat distribution, weight, or muscle mass: there also exists a relationship between body size and longevity across multiple species, including humans. On average, larger species seem to live longer and age more slowly—think about the fact that dogs age about seven times faster than do humans, who are both heavier and taller than dogs. But within species, that relationship flips around: larger individuals age more rapidly and live shorter lifespans than do smaller individuals. As with seemingly everything in aging, the relationship between body size and the rate of aging is complex and the result of an interplay between genetic, environmental, and lifestyle factors, most of which scientists are still investigating. In this episode of Longevity Science, Matt dives into the nuances of body size and aging rate, discussing currently available data about how the two interact, intriguing outliers and exceptions, and potential molecular and evolutionary drivers.

DON'T Take Resveratrol Until You Watch This Video | 34 - Healthspan Medicine #8 May 21, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Resveratrol is a naturally occurring polyphenolic compound found in various plants, including in the skins of grapes, blueberries, raspberries, mulberries, and peanuts. Its association with red wine has contributed to the illusion of the "French Paradox": the observation that French people have a relatively low incidence of heart disease despite a diet rich in saturated fats. If you were alive in the 2000s, you may remember cheering at the news that drinking red wine would protect your heart and help you live longer. Unfortunately, this claim is not true. Matt, who describes resveratrol as the "most debunked longevity molecule in history", spent several formative years of his scientific career in the depths of the resveratrol saga. Together with colleagues, and in parallel with other independent labs, he demonstrated that the apparent miracle powers of resveratrol were likely an artifact of the experimental methods used to test resveratrol-induced sirtuin activation, and that resveratrol actually had no significant lifespan-extending effects in vivo. In this episode, Matt presents a comprehensive analysis of the existing resveratrol literature, transports us to his earlier years of figuring the story out piece by piece with colleagues such as National University of Singapore Distinguished Professor of Biochemistry and Physiology Brian Kennedy, and shares his views on how bad science can have a profound influence on scientific fields, funding allocations, and public behaviour.

How He TRANSFORMED His Health by Taking Accountability. | 33 - Healthspan Journey #1 May 16, 2024

Subscribe to our channel: https://www.youtube.com/@optispan The journey towards prioritizing one's healthspan can be a circuitous path full of triumphs, setbacks and lessons. Challenges arise and old habits rear their ugly heads. Unforeseen obstacles test our resolve. The road is rarely linear and often leads us to unexpected places. In this episode, Matt chats with former Microsoft Chief Technology Officer and one of our first Optispan Trailblazers Stuart McKee about Stuart's early forays into drugs, smoking, and alcohol consumption, how he stepped off the train to get his health (and life) in order, and how the healthcare system can shape our attitude to healthspan optimization, for better or for worse. Stuart shares his meticulous approach to finding the right primary care doctor, strategies for weight loss from an obese baseline, and experiences with clomid therapy. They also discuss the influence of mindset and external influence on our healthspan optimization trajectories. Stuart is currently a Strategic Advisor to the software company Armada, where he collaborates with the executive team to identify opportunities, innovative solutions, and market priorities to drive awareness and growth for the company. He also serves as a substitute teacher for Washington's Northshore School District. He was previously Chief Operating Officer at the artificial intelligence and spatial analytics company Hayden AI and Chief Executive Officer of Optispan Geroscience LLC, a precursor to Optispan as it exists today. Stuart spent 16 years at Microsoft.

What YOU NEED to KNOW: https://youtu.be/SsDJZMlM1ko The Importance of Body Composition & Ways YOU can measure it: https://youtu.be/gM3aYTMsqNI The R-Files is a series of episodes about rapamycin, a naturally occurring compound originally discovered in soil samples from Easter Island, also known as Rapa Nui (hence the drug's name). Rapamycin belongs to a class of drugs called macrolides and has potent immunosuppressive and anti-proliferative effects. The drug has garnered attention for its potential anti-aging properties and has attracted research interest for its ability to extend lifespan and delay age-related diseases in various model organisms, including yeast and mice. In our fifth episode of the R-Files, Matt shares insights from his recent course of off-label rapamycin use, which he started in January 2024 and plans to continue for at least the next month or two. He describes improvements in joint pain and body fat loss as well as an unexpected bacterial infection, and speculates about whether rapamycin may have contributed to any of these effects. He also discusses rapamycin's half-life in his blood, which is significantly lower than that reported in the published literature.

Reversing Biological Age: Have we finally found the answer?? | 30 - LTW #5 May 07, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Matt recently exchanged a lively correspondence about biological age with Harold Katcher, cofounder of a stealth biotechnology company and inventor of E5. E5 is a compound consisting of the purified exosome fraction of blood from young piglets—in other words, young pig blood. Harold recently co-published a paper suggesting that injecting this young pig blood into rats made rats younger on several biological aging measures, including inflammatory markers and epigenetic aging signatures. Indeed, Harold has injected E5 into his own right hand and presented differences in the appearance of his right and left hands on social media. Putting pig blood into other animals (and into ourselves!) to reverse biological age might seem like a crazy thing to do. But this idea actually stems from a methodology with a decades-long history called heterochronic parabiosis, an area of research that explores the effects of joining the circulatory systems of different-aged organisms. In this experimental technique, researchers surgically connect two animals, typically mice, of disparate ages so that they share a common bloodstream. This union leads the older and younger individuals to exchange not just blood cells but also signaling molecules, growth factors, and other circulating factors. Remarkably, when an older animal is paired with a younger counterpart, it often experiences improvements in various aspects of health and tissue function, while the younger partner may exhibit corresponding signs of accelerated aging. The mechanisms underlying these effects are complex, multifaceted, and very much still under investigation. In this episode, Matt takes a magnifying glass to E5: what we know about the compound, how it affects lifespan, and how its impact on lifespan stacks up with that of other longevity inventions such as caloric restriction and rapamycin. He discusses whether Harold's recent paper truly proves a reversal of biological age and where his findings fit into the larger body of literature in the field. He also gives us a window into the methodology of heterochronic parabiosis, what the primary data about life expectancy gains through this intervention show, and whether heterochronic parabiosis-inspired interventions such as E5 are realistic approaches to human lifespan extension.

Aging Expert Explains How Healthcare got it ALL WRONG. | 28 - HSM #6 Apr 30, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: https://youtu.be/YhzgYaY7wto In April 2024, Matt delivered a presentation at a two-day congressional briefing on longevity science hosted at Washington, D.C.'s Mayflower Hotel by the Alliance for Longevity Initiatives (A4LI). Attendees included former Speaker of the House Newt Gingrich, Republican Congressman Gus Bilirakis, and Democratic Congressman Paul Tonko. We have decided to include Matt's presentation on our channel because we believe it delivers a valuable message. Healthcare has historically taken a piecemeal approach to diseases, addressing ailments in isolation. While this method has been successful at curing and sometimes even eradicating multiple diseases, it has its limitations. Aging is the single greatest risk factor for many of the chronic diseases we worry about in later life—think cancer, Alzheimer's disease, diabetes—and involves a complex interplay of molecular, cellular, and physiological changes that underlie a myriad of health conditions. There is a reason that your average 80-year-old has more health problems than your average 18-year-old. As our understanding of human biology deepens, it is becoming increasingly evident that we need to broaden our focus beyond individual diseases and incorporate the biology of aging into strategies for improving human health and resilience to disease. Achieving this paradigm shift towards addressing the fundamental processes of aging, which will require interdisciplinary collaboration between scientists, clinicians, policymakers, and the public, will give us the potential to mitigate multiple age-related diseases simultaneously. In this episode, Matt covers how we got here, the differences between 19th and 21st century medicine, and the importance of targeting the biological aging process to create transformative results in tackling healthcare challenges. He also discusses policy reforms that would be useful for the cause, including changes to FDA regulation, a rethinking of insurance reimbursement, and how he would reslice the federal funding pie.

Inside this Non-profit's AMAZING Strategy to Fight Aging | 27 - Dylan Livingston Apr 25, 2024

Subscribe to our channel: https://www.youtube.com/@optispan We talk a lot about the science of longevity and healthspan on the Optispan podcast—how DEXA scans work, what an optimal rapamycin dose might look like, how the intersection of optogenetics and mitochondria are helping us understand biological aging, what supplements one might consider taking and why. But the longevity field runs on way more than just science. It takes a village—a community of researchers, engineers, entrepreneurs, investors, regulators, and beyond who believe in the value of tackling the biology of aging as a crucial strategy for extending healthy lifespan—to create tangible results that benefit as many people as possible. At Optispan, we're eager to support and interact with the many levers that keep this machine going. One of these is the Alliance for Longevity Initiatives (A4LI), a nonprofit organization focused on catalyzing social and political action that will benefit the longevity field. In this episode, Matt chats with A4LI founder, president, and CEO Dylan Livingston about forming a bipartisan longevity science caucus, redirecting funding towards geroscience research, and engaging with policymakers to help them understand the importance of transitioning towards a proactive healthcare model. Dylan, who founded A4LI in 2021, served as a field organizer for President Joe Biden's 2020 presidential campaign. He also worked as a community organizer for Organizing Corps 2020, where he registered hundreds of Democratic voters in Pennsylvania for the 2020 presidential compaign. Dylan graduated from Haverford College with a B.S. in physics and a minor in economics. Matt joined the A4LI Board of Directors in 2024.

Guess his body fat percentage | #26 - Healthspan Medicine #5 Apr 23, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related videos: The Importance of Body Composition & Ways YOU can measure it | 21 - HSM #3: https://youtu.be/gM3aYTMsqNI A DEXA (dual-energy X-ray absorptiometry) scan is an advanced imaging procedure for measuring bone density and composition. DEXA scans utilize two different energy levels of low-dose X-ray beams—one absorbed mostly by soft tissue, and the other absorbed mainly by bone—to differentiate between bone, fat, and lean tissue. In so doing, they provide noninvasive and detailed information about bone health, risk of osteoporosis or fractures, and body composition. While medical practioners typically perform DEXA scans on the lower spine and hips, they can also perform DEXA scans on the whole body for the purposes of early detection and intervention. In our multi-part DEXA series, we go deep into DEXA scans: what they measure, how to interpret them, and how to use information from your own DEXA scan for healthspan optimization. This week we're on Part II, where we analyze the DEXA scans of Matt and Optispan Lead Healthspan Analyst and certified personal trainer Nicholas Arapis. We unpack the nuances of the various metrics a DEXA scan measures, discuss potential noise in the results, and hear from Nick about what he would tell Matt to do if he was coaching Matt based on his DEXA scan results.

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: The Importance of Body Composition & Ways YOU can measure it | 21 - HSM #3: https://youtu.be/gM3aYTMsqNI We talk a lot about making a shift from reactive disease care—a 20th century healthcare mindset—to preventative and proactive health measures designed to optimize longevity and healthspan before disease sets in. Rather than waiting for chronic conditions to manifest and treating their symptoms post hoc, we encourage investing resources in preemptive care and empowering individuals to act as partners with healthcare providers in their own wellbeing. Preventative medicine can feel like a lot—cancer screenings, for example, are crucial for early detection and treatment, but can be logistically and emotionally daunting. But proactive healthcare doesn't always need to be complicated. In this episode, Matt goes through what he sees as low-hanging fruit in preventative medicine: simple steps that lend themselves to straightforward measurement, are easy to improve without invasive intervention or drastic lifestyle changes, and will pay dividends in increasing our overall health.

These 14 Medications are linked to lower death rates in humans | 23 - Longevity this Week #4 Apr 12, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Related episodes: People are GETTING THIS WRONG about Supplements & My Supplement List | 17 - Healthspan Medicine #2: https://youtu.be/_UXk_ynCNUs Transforming Our Understanding of Healthcare Through Geroscience | 11 - LS #4: https://youtu.be/LCPvF-SlZIU We typically think of prescription drugs as targeted treatments designed to address the underlying mechanisms and biochemical pathways associated with specific diseases or conditions. For example, healthcare providers commonly prescribe statins that lower cholesterol levels and reduce cardiovascular disease risk by inhibiting the enzyme involved in cholesterol synthesis. Similarly, doctors might prescribe antibiotics to target bacterial infections by disrupting the bacteria's growth or killing them outright. But prescription drugs may have multiple uses or indications beyond their original intended purpose. A recent preprint from the biotech startup EPITERNA describes a study exploring the link between prescription drugs and human lifespan. Researchers analyzed more than 40 years of prescription drug data from over 500,000 patients in the UK Biobank to examine how commonly prescribed medications affect mortality risk. Many drugs have negative consequences for lifespan for reasons that include drug resistence, drug dependency, and side effects such as organ damage and immunosuppression—but a number of drugs actually appear to be beneficial for longevity. In this episode, Matt goes over the study's top-performing drugs for lifespan, and discusses how we might interpret and extend these intruiging findings about common prescription medications.

“Zombie” Senescent cells may play HUGE role in LIVING LONGER, Here's How: | 22 - Natalia Mitin Apr 10, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Senescent cells, cells that cease to divide and proliferate while remaining metabolically active, are a complex and intriguing aspect of biological aging. They serve as both a protective mechanism against cancer, preventing damaged cells from uncontrollable replication, as well as a contributor to tissue dysfunction and age-related pathologies such as cardiovascular disease, neurodegenerative disorders, and diabetes. The precise mechanisms that underlie senescence and its contributions to the aging process remain areas of ongoing investigation and debate. In this episode, Matt chats with Sapere Bio co-founder and CEO Natalia Mitin about measuring cellular senescence, using those measurements in the clinic, and the complex and heterogeneous role of cellular senescence in aging and disease. They also discuss Natalia's personal experiences using rapamycin off-label to improve energy levels and immune function, the importance of monitoring biomarkers when using off-label medications, and Natalia's thoughts on "rapamycin for all". Prior to co-founding Sapere Bio, Natalia served as an assistant professor at the University of North Carolina at Chapel Hill's Department of Pharmacology. She spent over two decades developing assays for use in cancer research. She holds a B.S. in chemical engineering from the Mendeleev Institute for Chemical Technology and a PhD in biochemistry and molecular biology from Bowling Green State University. Optispan uses the SapereX test in its healthspan optimization program.

Does this Dog Supplement Really Work to REVERSE AGE? (PART 2) | 19 - Longevity This Week #3 (2/2) Mar 29, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Part I: https://youtu.be/-ujIfZXGbDA At the Optispan Podcast, we aim to help you become your own detective of research in the geroscience field and beyond. Critical thinking is our compass. We want to help you dig into every aspect of a study: are the methods they used solid? Was the sample size big enough? Did they crunch the numbers right? What's the most reasonable interpretation of the data? Might a conflict of interest skew the results? In Part II of a two-part series about a recent study of how a supplement called "Leap Years" affects canine cognitive function, Matt takes a magnifying glass to a bioRxiv preprint describing the clinical trial's methodology and findings. Beginning with a sentence-by-sentence dissection of the study's abstract, he describes various things he finds unusual or questionable about the way researchers ran and publicized the clinical trial: exclusion of certain data, a lack of disclosure around the supplement's ingredients, the use of an assessment tool that was not validated for its intended purpose, and more. He discusses conclusions we can actually draw from the study based on the information the researchers have supplied, and whether or not he would give the supplement to his own dog. This episode is Part II of a two-part series. In part I, Matt talks about the press release announcing the drug's potential ability to reverse age-related decline and improve cognitive function in dogs, as well as the importance of interrogating bold advertising claims rather than taking them at face value.

Does this Dog Supplement Really Work to REVERSE AGE? | 19 - Longevity This Week #3 Mar 27, 2024

Subscribe to our channel: https://www.youtube.com/@optispan When drug development companies promote their products, they understandably highlight the benefits and potential relief they offer. While these advertisements can make the products seem like game-changers for health issues, it's important not to swallow the marketing spiel whole. Question it, test it, poke and prod it to see if it holds up under scrutiny. Take the time to research the drug independently and examine what the press release or advertisement claims. Look for unbiased sources like medical journals, regulatory agencies, or reputable health websites that might provide a more balanced view of the drug's efficacy and safety. Part of our mission at the Optispan Podcast is to encourage critical thinking about science, including and especially science related to health- and lifespan. In this episode, Matt puts the spotlight on a recent press release that made a splash in the longevity community: an announcement of a combination senolytic/NAD booster product that researchers suggested has the potential to reverse age-related decline in dogs. Matt goes over claims the press release and the researchers make, what the product might contain (spoiler: we're not sure), what we do and don't know about it, and his personal feelings about whether it should actually be on the market for pet owners to purchase. This episode is Part I of a two-part series. In part II, Matt will go deeper into the actual research behind claims in the press release and examine how well it withstands critical evaluation.

Rapamycin belongs to a class of drugs called macrolides and has potent immunosuppressive and anti-proliferative effects. The drug has garnered attention for its potential anti-aging properties and has attracted research interest for its ability to extend lifespan and delay age-related diseases in various model organisms, including yeast and mice. In the fourth episode of the R-Files, Matt discusses research demonstrating that rapamycin rejuvenates the aged mouse immune system to respond to a flu vaccine as if it were in a youthful state. He also discusses papers suggesting that rapamycin may have similar effects on human immune systems.

People are GETTING THIS WRONG about Supplements & My Supplement List | 17 - Healthspan Medicine #2 Mar 20, 2024

Subscribe to our channel: https://www.youtube.com/@optispan As a longevity scientist, Matt often receives questions about what supplements he takes—so we decided to make an episode where Matt discusses his supplements protocol. This episode isn't meant to provide a playbook for you to follow. We want to emphasize the importance of approaching supplements with discernment and an understanding that they are not a substitute for wholesome nutrition and other healthy lifestyle practices. The allure of supplements is understandable: they promise us vitality, strength, and longevity in a convenient capsule. But their indiscriminate consumption can be risky. Blindly reaching for supplements without considering their necessity or potential interactions with medications could lead to adverse effects. Further, the supplement industry isn't rigorously regulated in many regions, leaving room for mislabeling and contamination. There is no such thing as a one-size-fits-all solution when it comes to supplements. In this episode, Matt discusses his relatively conservative supplements approach, debunks some of the myths associated with supplement consumption, and provides some advice about how to evaluate products that come from a profit-driven industry with few guardrails in place.

CAR T Cells: The Ultimate Anti-Aging Solution? | 16 - Longevity This Week #2 Mar 19, 2024

Subscribe to our channel: https://www.youtube.com/@optispan While scientific papers are generally considered trustworthy sources of information, it's important to approach them with a critical mindset and to avoid blindly accepting their claims. The peer-review process, which helps ensure high research quality, is not foolproof. Errors or biases can slip through the cracks. In reading a paper, we should independently evaluate the evidence, scrutinize the methodology, and reflect on alternative interpretations of the data. Considering the influence of funding sources, conflicts of interest, and the potential for selective reporting can also help in maintaining a healthy skepticism about new information. In this episode of Longevity This Week, Matt takes us through a recently-published paper about the effects of senolytic CAR T cell therapy on the aging process in mice to help us figure out whether the paper's claims hold water. He also analyzes a BBC article describing the findings. Popular press adaptations of the scientific literature often serve as a useful bridge between the complex world of research and the general public, but can be misleading in their attempts to make science accessible. They might, for example, inadvertently distort or oversimplify findings, exaggerate the significance of results, or selectively report research while ignoring contradictory or inconclusive evidence from other sources. We hope this episode will encourage viewers to approach science communication with a discerning eye, and to stay vigilant, curious, and open-minded in learning about the latest discoveries and developments.

Subscribe to our channel: https://www.youtube.com/@optispan At its best, healthcare isn't just about extending lifespan—it's also about enhancing the vitality of our years. Over the last century, the healthcare system has made enormous strides in keeping sick people alive. The next step is to use proactive, preventative healthcare to stop them from getting sick at all. The Lost Decade—the 10 or so years that many people spend suffering from poor health and/or disability in older age—doesn't have to be a given. In this episode, Matt discusses why he left academia to help start a healthcare revolution, why sickness and decline don't have to define our final years, how decades of geroscience research have informed his views of healthcare, and what he thinks healthspan optimization should look like.

Longevity Science 2024: New Insights on "The Hallmarks of Aging" & What They Mean | 14 - LS #5 Mar 11, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Over a decade ago, five researchers published a paper proposing the Hallmarks of Aging paradigm: a set of cellular and molecular processes that underlie the aging process in different organisms. These hallmarks encompass a range of interconnected pathways, including genomic instability, telomere attrition, epigenetic alterations, loss of proteostasis, disabled macroautophagy, deregulated nutrient signaling, mitochondrial dysfunction, cellular senescence, stem cell exhaustion, altered intercellular communication, chronic inflammation, and dysbiosis. Together, the hallmarks contribute to the gradual decline in physiological function and increased susceptibility to age-related diseases that occurs with age, and provide a framework for understanding how we age. In this episode, Matt takes us through a quick download of each hallmark of aging, talks about some of the paradigm's shortcomings and limitations, and discusses the implications of the Hallmarks of Aging paradigm for the geroscience field.

Transforming Our Understanding of Healthcare Through Geroscience | 11 - LS#4 Mar 04, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Everything we talk about on The Optispan Podcast has geroscience at its root, so we decided to make an episode about it. Geroscience is the study of the mechanisms connecting biological aging with disease and disability. The term first appeared in the scientific literature around 2008, and its use has steadily increased since as researchers have discovered more about the aging process and its impact on our health. While it's clear that aging biology is at the root of the diseases and disabilities that most people get sick with and die from in their later years, it's been a challenge to get the field the traction and support that other fields enjoy, in part because we are used to a "disease care" model of waiting until people get sick and only then addressing their symptoms and/or curing their disease. In this episode, Matt dives into the geroscience hypothesis and how it underpins the way we age, entrenched cultures in industries from drug development to insurance to regulation, and why he's excited to create a geroscience-inspired disruption in the medical and healthcare industries.

What a 93-Year-Old Rowing Champion Can Teach Us About Aging Well | 10 - Longevity this Week #1 Mar 01, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Defining "healthspan" & its role in living longer: https://www.youtube.com/watch?v=cI6CNFeBl88 Longevity This Week is a series of episodes discussing new findings or articles relevant to geroscience, longevity, and healthspan that may have popped up in the news. This week we're featuring Richard Morgan, a 93-year-old rowing champion whom the Washington Post recently described as being "as fit as a 40-year-old". We talk about Richard's diet, exercise routine, and other aspects of his lifestyle that may have led to his enviable state in older age. We also discuss a recent Wall Street Journal article about how Americans are spending more of their lives in poor health, and about how "sickspan"—the amount of time we spend sick near the end of our lives—might change in years to come.

Biological Age & what it REALLY means | 9 - Longevity Science #3 Feb 28, 2024

Subscribe to our channel: https://www.youtube.com/@optispan Understanding Aging & Disease and How They're Related: https://www.youtube.com/watch?v=94_Rqe2m1C0&feature=youtu.be Biological age—that is, how old your cells and tissues are based on physiological function—is a multifaceted and intricate concept that transcends numerical representation. Unlike chronological age, which refers simply to the number of years you have been alive, the concept of biological age delves into the dynamic interplay between physiological processes, genetic predispositions, and environmental influences that collectively shape an individual's health trajectory. Geroscientists are currently studying the biological mechanisms that might impact your biological aging rate and perhaps reverse some of the functional declines that accompany aging.

An introduction to the study of RAPAMYCIN | 6 - R-Files w/ Matt Kaeberlein Feb 12, 2024

The R-files is a series of episodes about rapamycin, a naturally occurring compound originally discovered in soil samples from Easter Island, also known as Rapa Nui (hence the drug's name). Rapamycin belongs to a class of drugs called macrolides and has potent immunosuppressive and anti-proliferative effects. The drug has garnered attention for its potential anti-aging properties and has attracted research interest for its ability to extend lifespan and delay age-related diseases in various model organisms, from yeast to mice. Matt, who has spend a significant part of his career studying rapamycin, will discuss rapamycin and its relevance to longevity research.

I spent the first few decades of my career doing scientific research into the biology of aging, trying to understand the finer details of how humans age in order to facilitate translational interventions that promote healthspan and improve quality of life. Now I want to take some of that knowledge out of the lab and into the hands of people who can really use it. On this channel I talk about all things aging and healthspan, from supplements and nutrition to the latest discoveries in longevity research. My goal is to lift the veil on the geroscience and longevity world and help you apply what we know to your own personal health trajectory. I care about quality science and will always be honest about what I don't know. I hope you'll find these videos helpful!
