What are the risks of using running apps? May 29, 2026

Show notes

In case you haven’t noticed, running is very much in vogue these days. We talked about the London Marathon on Do You Really Know last month, but you don’t have to out yourself through the ordeal of a 26-mile distance to enjoy running. It can just as easily be a 20 or 30 minute jog in the park, or in the streets of your local area.

And of course as with any trend in society, the running boom has gained significant traction on social media. People love sharing their progress on mainstream socials, as well as through dedicated running apps like Adidas Running, Nike Run Club, or Strava.

What do you mean by that? Most of us aren’t heads of state or secret service agents though, are we? In under 3 minutes, we answer your questions!

Are baths or showers better for our health? May 29, 2026

Show notes

When it comes to getting clean, some people prefer chilling in the bath for a good half an hour or more, while others like how quick and practical it is having a shower. Let’s consider the two choices from a health perspective.

It's pretty common knowledge that taking a bath isn't very eco-friendly, in terms of water consumption. Of course there are variables at play here when comparing the two. When taking a bath, you only really need to fill around a third of the tub up, so your torso is submerged when you lie down. But some people will fill it higher, which obviously uses more water. When taking a shower, it depends how long you keep it running for and how powerful the flow rate is.

What does taking a bath do to our bodies? What about its impact on the cardiovascular system? Are there any points of comparison where taking a shower is better? In under 3 minutes, we answer your questions!

What does it mean to be a seenager? May 28, 2026

Show notes

You may have heard the term "seenager" being used lately. It's a new buzzword that describes a demographic group that's becoming increasingly important in our society.

In simple terms, a seenager is a senior teenager. It refers to people aged 55 and over who are still young at heart and refuse to let their age define them. Seenagers are active, social, and engaged in their communities. They're not content to sit back and watch the world go by – they want to be a part of it.

So why are we seeing more and more seenagers these days? What are some of the characteristics of a seenager? Why is it important to recognize and celebrate the seenager demographic? In under 3 minutes, we answer your questions!

Why is exercise good for my skin? May 28, 2026

Show notes

It doesn’t matter which fancy moisturizers or expensive skincare routine you use, nothing quite matches how your skin looks and feels after an intense workout. Just take a look in the mirror after you’ve finished exercising and you’ll likely see smooth skin and a glowing complexion.

That’s right, in addition to the positive impact on our physical and mental health, exercise can also improve our skin health. And there are studies out there which have backed it up. For example, biology journal Aging Cell reported on one in 2015, which found that vigorous exercise led to visibly younger-looking skin.

What’s the science behind that? How exactly does exercising and sweating purify skin? Are some types of exercise better for your skin than others? In under 3 minutes, we answer your questions!

What are mirror hours? May 28, 2026

Show notes

Ever checked the time on your phone or TV set and seen a quirky number like 13:13, 11:11 or 20:20? Well of course you have, but what you may not know is there’s actually a name for such numbers: mirror hours!

Basically, when you’re looking at a digital time display, you see a mirror time if the minute number and the hour number are the same. It refers to the symmetry you see on either side of the colon separating the two numbers. Most people are pretty indifferent to this, or see it as a vaguely amusing quirk at most. But for some it goes much further and they believe mirror hours have a mystical or even spiritual meaning, making them far more than just another minute in the day.

What kind of meaning are we talking about? How many different mirror hours are there? ⁠In under 3 minutes, we answer your questions !⁠

Why is it so hard to remember people’s names? May 27, 2026

Show notes

Ever met someone… and forgotten their name almost instantly? Awkward, right, especially after chatting for a few minutes. But if that happens to you a lot, you’re definitely not alone.

One reason is that first names don’t really mean anything on their own. They don’t tell you what someone looks like, what they do, or what they’re like. And our brains are much better at remembering information when it’s tied to something concrete.

So, why does this happen? So why do we remember some names but not others? In under 3 minutes, we answer your questions!

Why do our tastes change as we get older? May 27, 2026

Show notes

Think back to when you were a kid and there was a type of vegetable you simply wouldn’t go near, let alone eat. It might have been broccoli, Brussels sprouts or spinach for example.

Or perhaps another type of food like seafood, which now as an adult you actually quite like, or can tolerate at least. It’s not a coincidence; there are scientific explanations for why our taste preferences evolve with time.

What tastes do children actually like most then? Does this hypersensitivity decrease with age then? Do other factors play a role in changing our food preferences? In under 3 minutes, we answer your questions!

What is the olive theory from Tiktok? May 26, 2026

Show notes

The olive theory actually started trending on Tiktok as of early 2023, leading younger generations to get familiar with How I Met Your Mother and one of its most popular relationship theories. At the time of recording, the #olivetheory hashtag has accrued over 130M views.

Fans of 2000s sitcom How I Met Your Mother can no doubt remember how the main character Ted Mosby is a hopeless romantic, and spends the duration of the series searching for his soulmate. But only the most hardcore of fans will remember the very first episode of the Hulu series, when Ted introduces something called the olive theory when talking about relationships.

What on earth do olives have to do with romantic compatibility? In under 3 minutes, we answer your questions!

What is environmental racism? May 26, 2026

Show notes

What is environmental racism?

We’ve covered a lot of environmental issues on Do You Really Know? so regular listeners will be well aware of how the climate crisis is affecting the whole planet. But it’s important to also note how these problems don’t affect everyone equally. People in developing countries, particularly in the Southern Hemisphere, are already feeling the impact on their income, physical health and surrounding environment. That’s despite industrialised countries having contributed far more to global warming overall.

What kind of environmental problems are we talking about exactly? Do you have any concrete examples? What about on an international level? ⁠⁠In under 3 minutes, we answer your questions!⁠⁠

Should you be reducing salt in your diet? May 26, 2026

Show notes

Salt is a common ingredient in many foods, and it’s essential for our health. Salt is made up of sodium and chloride, two minerals that help regulate fluid balance, blood pressure, nerve and muscle function.

According to the World Health Organization (WHO), adults should consume less than 5 grams of salt per day, which is equivalent to about one teaspoon. However, most people eat more than that.

But how much salt do we need, and how much do we actually consume? What happens if we eat too much salt? Does that mean we should avoid salt altogether? In under 3 minutes, we answer your questions!
