What's the best way to organise my fridge? Aug 02, 2026

Show notes

Arranging your fridge isn't just a way to save space. It's primarily about ensuring optimal preservation of food products and thus preventing the proliferation of bacteria. According to UK Research and Innovation, there are around 2.4 million cases of foodborne illness in the country every year.

First and foremost, it's important to know that fridges with ventilated or circulated cold air have a more consistent temperature than those with static cold air. In the latter case, the temperature varies based on the distance from the cold source, so you should start by identifying the coldest area of your fridge.

What should be stored in the coldest part? Should packaging be removed? How should you be cleaning your fridge? In under 3 minutes, we answer your questions!

Do you ever feel like time is slipping through your fingers? That you had several hours to complete one or two simple tasks, but you didn't notice the clock ticking away? The problem might stem from poor time management or a tendency to procrastinate.

What is misogynoir? Aug 01, 2026

Show notes

You may remember that we discussed the idea of intersectionality in a previous episode of Do You Really Know?. The term describes how characteristics like race, class, gender, sexual orientation and physical ability “intersect” when it comes to social discrimination.

Well, today we’re going to talk about a more recent term for the unique type of discrimination that black women face: misogynoir. Just last month, British charity Glitch released its “Digital Misogynoir Report”,which was based on analysis of close to 1 million text-based messages about women posted on social media.

Where does the term misogynoir come from? How does misogynoir manifest? In under 3 minutes, we answer your questions!

Should I walk 10000 steps a day? Aug 01, 2026

Show notes

Most of us are familiar with the idea that you need to take 10 thousand steps per day to stay healthy but getting to this magic number is not that easy. The 10,000-step target first became popular in Japan in the 1960s.

A clockmaker capitalising on people's new interest in fitness following the 1964 Tokyo Olympic Games made a pedometer with a name that, when written in Japanese characters, resembled a walking man and coincidentally translated as “10,000-steps metre.” A study of over 78,000 people in the UK between 2013 and 2015 using wearable trackers was published in the journals JAMA Internal Medicine and JAMA Neurology.

Where did we get the number 10 thousand from? Does that mean that we do not need to take 10 steps? So how many steps should I be aiming for per day? In under 3 minutes, we answer your questions!

Why do some people say slum tourism a bad thing? Jul 31, 2026

Show notes

Most people who can afford to go on holiday tend to want to spend their time in glamorous, picturesque locations. But there are actually some people who choose to visit disadvantaged areas instead, to see the less glamorous side of countries that are often romanticised.

This is known as ghetto tourism, or slum tourism, and it’s been the subject of some quite fierce debate over the years. Some people see it as a form of voyeurism, a glimpse into others' struggles for personal gain. While others argue that it’s a legitimate way of fostering understanding and empathy.

What are the origins of slum tourism? Does it still happen these days? In under 3 minutes, we answer your questions!

What can supermarkets do to reduce food waste? Jul 31, 2026

Show notes

November is synonymous with Black Friday, great deals but what cost? Over consumption is endangering our already fragile planet. Is it time to change our ways? This week Do You Really Know is highlighting concepts and initiatives about reducing our consumption.

According to the World Wildlife Foundation, roughly a third of all produced in the world goes to waste. What’s more the United Nations’ Food and Agricultural Organisation says that food waste accounts for a third of all human-caused greenhouse gas emissions and 8% of greenhouse gas emissions in total. With that in mind, we might feel guilty when we don’t finish our dinner, or leave something in the fridge for too long and have to throw it out.

Where do these problems come from? Do new technologies have a part to play in this? What about imperfect food items? In under 3 minutes, we answer your questions!

What is bae-realing, the new dating trend? Jul 31, 2026

Show notes

Ever since social media came along, dating trends have evolved constantly. They tend to reflect changes in society too. In previous episodes of Do You Really Know, we’ve talked about dawn dating, sneating and ghosting for example.

There are so many different terms out there, and not all of them are positive. Here’s another one you may have heard of recently, in particular if you’re single and use dating apps; bae-realing. You might have started to feel like all these manufactured dates aren’t natural, that they’re unwholesome. If that’s the case, you may well be seduced by the authenticity and even radicalism of bae-realing. It’s been called “a breath of fresh air” by Stylist magazine.

Where does the name come from? Why has bae-realing become a trend now? How can I take part in the trend? In under 3 minutes, we answer your questions!

How can I stop smoking? Jul 30, 2026

Show notes

We all know that the effects of tobacco on the human body are devastating. The World Health Organisation says that it kills more than 8 million people each year, making it one of the biggest public health threats the world has ever seen.

It’s hardly surprising when you consider that cigarettes contain over 4,000 chemical substances, and at least 50 of them are carcinogens, meaning they are linked to an increased risk of cancer. Many people will attempt to quit smoking as part of their New year’s resolutions, and we’re here to provide some information on the best ways to do so. It seems so, at least according to the most recent large-scale study on the subject which was published by Jama Network Open in October 2022.

If I give up, will my body ever fully recover? What different methods are out there? In under 3 minutes, we answer your questions !

What is the windscreen phenomenon? Jul 30, 2026

Show notes

The windscreen phenomenon is the observation of the gradual disappearance of insects on the planet.

If you regularly use your car for long trips, you’re probably accustomed to seeing squashed flies, wasps and gnats on your windscreen from time to time. This is totally normal, but in recent years, it’s become a much rarer sight for drivers, and the significance is greater than you might first think.

Isn’t not having to scrape dead insects off the windscreen a good thing? How can we be so sure that insects are disappearing? Could it just be an impression? What’s causing this decrease in insect population then? ⁠In under 3 minutes, we answer your questions !⁠

Could the deep work technique help me concentrate better at work? Jul 30, 2026

Show notes

Distractions in the workplace are almost endless, from Slack group notifications to questions from colleagues to the dozen or more tabs you’ve got open in your browser. By the time your next meeting comes along, you realise two hours have passed and you’ve barely done any productive work at all.

Sound familiar? Thankfully there’s a method to improve your efficiency and concentration which may help. It’s called deep work. We owe it to Cal Newport, a computer science professor at Georgetown University in the US. Newport is a renowned figure in personal development and in 2016 he released a self-help book entitled: Deep Work: Rules for Focused Success in a Distracted World, which would go on to be a bestseller.

Where does the concept come from? What’s the best way to concentrate on deep work? What if my boss and colleagues think I’m being rude? In under 3 minutes, we answer your questions!
