Is it dangerous to drink too much water? Apr 05, 2026

Show notes

All our organs contain water, even our bones. In total, more than half of our body is made up of it, or 45 litres for a person weighing 65 kg. The water we drink is needed to eliminate waste: 3 litres disappear every day via urine, perspiration and breathing. It also helps maintain our body temperature at around 37 degrees and is essential for digestion.

The recommended daily intake of water is around 6, 25cl glasses of water a day, in other words about 1.5 litres. For some of us, this rhythm is difficult to maintain, especially as it's not always very exciting to simply drink water. If this is you then you could try herbal teas or flavoured water.

How can you tell if you're drinking too much? What can you do if you're concerned? In under 3 minutes, we answer your questions!

What is Buccal Fat Removal? Apr 04, 2026

Show notes

Buccal fat removal is a type of plastic surgery that involves removing the buccal fat pads from your cheeks. These are rounded pads of fat that are located between your facial muscles, in the hollow area beneath your cheekbones. Their size affects your face shape; the larger they are the rounder or fuller your face appears.

The goal of buccal fat removal is to thin the cheeks and define the facial angles. Some people may want to do this to achieve a more sculpted or chiseled look, or to enhance their cheekbones and jawline. This procedure is also sometimes called a cheek reduction.

Why has it become more popular recently? How is the procedure done? What are the risks with this procedure? In under 3 minutes, we answer your questions!

Why has far-right terrorism increased so much? Apr 04, 2026

Show notes

In early December 2022, German authorities carried out a sting operation on the neo-Nazi Reichsburger group that was plotting to overthrow the country’s government through a coup. It was one of Germany’s biggest ever counterterror operations, seeing 3000 police officers make 300 raids across 11 regions of the country, and led to a total of 25 arrests.

The so-called Citizens of the Reich are just one example of a dangerous threat that is becoming more and more widespread in the West: that of violent far-right terrorism. 2019 saw the Christchurch mosque attack in New Zealand, which killed 51 people, and a school shooting targeting the majority Latino community of El Paso, Texas. The following year, Germany saw the Hanau shisha bar shootings, and the murder of migrant-friendly MP Walter Lubcke.

What are the aims of right-wing extremists? How has right-wing terrorism changed in recent years? Who tends to radicalise? In under 3 minutes, we answer your questions!

What do you get better at with age? Apr 04, 2026

Show notes

You might think that ageing is all about decline and deterioration, but that’s not the whole story. In fact, there are many aspects of life that improve as we grow older, such as happiness, wisdom, relationships, and even some cognitive skills. “Our societal narrative is not based on science – it’s based entirely on prejudice.

Contrary to popular myth, we never stop learning or growing new brain connections.” says Daniel Levitin, professor of neuroscience at McGill University, who sought to challenge people's ideas on ageing in his book ‘The Changing Mind’.

Why do we keep rewatching the same films and TV shows? Apr 03, 2026

Show notes

Friends, Harry Potter, The Office, Home Alone, Love Actually… Most of us have that series or that film we’ve seen at least ten times.

And yet, when stress kicks in or a rainy Sunday arrives, we sink into the sofa and press play again. It’s almost like we’re drawn back to stories we already know by heart.

So what makes us hit replay? But why do we rely on these “comfort movies”? Are there any other upsides? In under 3 minutes, we answer your questions!

Why do our bellies get fatter as we get older? Apr 03, 2026

Show notes

As the years go by, those extra inches around the abdomen tend to sneak up on us, and that’s especially true once we hit our fifties. One major player is hormonal shifts. For women, the onset of menopause often brings about weight gain and a burgeoning belly, thanks to a decline in estrogen levels that prompts the body to store fat in the midsection.

And fellas, you're not off the hook either—ageing comes with its own hormonal downturn. A drop in testosterone can lead to an uptick in visceral fat. With time, our bodies are no longer the calorie-burning powerhouses they once were, particularly at rest. Past the age of fifty, the body’s muscles start to shrink, causing a dip in baseline metabolism, which is the ability to burn calories.

Does our metabolism changes with age? And how can you fend off that belly bulge? In under 3 minutes, we answer your questions!

Are gas cookers dangerous? Apr 03, 2026

Show notes

Gas cookers are a common feature in many kitchens, often preferred by chefs and home cooks for their precise temperature control but gas cookers emit a number of harmful substances when they are in use and even when they are off that can pollute the indoor air and harm your health.

Nitrogen dioxide, or NO2, is a gas that is produced when natural gas is burned at high temperatures. It can damage your airways and worsen asthma and COPD. A recent report by the Dutch Lung Foundation found that gas cookers increased the risk of asthma in children by 42%.

What are some other of these pollutants and their effects? And what can you do to reduce these risks? In under 3 minutes, we answer your questions!

How did flat Earth conspiracy theory start? Apr 02, 2026

Show notes

Flat Earthers believe that the Earth is not spherical, but rather a flat disc and the Sun and the Moon are also flat discs that circle above the Earth. According to them the edges of the world are surrounded by a wall of ice, which is what we know as Antarctica. And as for the pictures of the Earth from space - they are all fake, part of a huge conspiracy to hide the truth.

The earliest cultures that believed in a flat Earth were the ancient Egyptians, Babylonians, and Greeks. They had different models that depicted the Earth as a flat surface, often supported by pillars or resting on a giant animal. But not all ancient Greeks shared this belief.

Why have people started believing in this again? And why do some people still believe in the flat Earth theory despite all the evidence that contradicts it? In under 3 minutes, we answer your questions!

What is body neutrality? Apr 02, 2026

Show notes

According to a 2019 online survey conducted by the Mental Health Foundation and YouGov, over a third of UK adults have felt anxious or depressed because of their body image. Although that particular survey didn’t specifically address how gender affected the chances of someone feeling unsatisfied about their appearance, the summary acknowledged that it is often more common among young women.

We’ve talked about the increasing popularity of the body positive movement in the past on Do You Really Know, but such findings show that it hasn't yet fundamentally shifted women's perspectives on their bodies. The pressure to have a ‘perfect body’ remains significant. However, there’s a new trend out there which suggests adopting a more measured and neutral stance towards our appearance, rather than advocating unconditional self-love. It’s known as body neutrality.

Where does this movement come from? So, does this mean we shouldn't love our bodies anymore? In under 3 minutes, we answer your questions!
