2025/11/01

There’s a lot of popular ideas out there about body hair removal. Shave too much and the hair becomes thicker. Wax, and it will gradually start thinning out. It can be hard to know who or what to believe. Both women and men increasingly spend a lot of their time and money removing body hair, even though it acts as a barrier to bacteria, and sexually transmitted diseases in the case of pubic hair. Shaving with a razor, using an electric epilator and waxing all have their own pros and cons. But

2025/11/01

Polish-American man Leo Gerstenzang is credited with inventing the humble cotton bud in the 1920s, an item which has since gone on to be used for many different purposes, having originally been thought up as a baby hygiene product.Yougov research from 2019 found that 62% of Brits use cotton buds to clean their ears, and 22% of us only use them for that purpose.

Why are we afraid of the dark?

Do you really know? ·

2025/10/31

Fear of the dark is very common for children and usually starts between the ages of 5 and 10. At this age, children become more aware of the dangers around them. However, they often have difficulty correctly assessing just how real these dangers are. Usually, this fear disappears naturally as children gain confidence and grow up, but in rarer cases it may persist into adulthood. Principally, it is because darkness alters our main sense of reference: sight. This sense has taken over from the others,

2025/10/31

We’ve all got fears. For some, it’s the dark, for others, it’s spiders, heights, or maybe even something as ordinary as a phone call. But when those fears take root and are no longer reasonable; when they take over, that’s when they cross into the territory of phobias. Phobias remind us that our brains, for all their brilliance, aren’t always working in our favor and are flawed. According to a survey by Anxiety UK, there are ten phobias that show up more often than the rest. So what are these

2025/10/31

Halloween is here and if you’re anything like us, you’ll be frantically doing some last-minute pumpkin carving or stocking up on sweets for trick-or-treaters. Maybe you’re going to a Halloween party dressed up as a ghost, witch or any other kind of spooky creature. But have you ever wondered where all these quirky customs came from? While Halloween seems like a very modern celebration, its origins actually go back well over 1000 years. It started out with an ancient Celtic festival called Samhain

In November 2023, a spooky makeup trend took TikTok by storm. Users posted images of themselves with full-coverage, pale foundation for a ghostly vibe, intense grey contouring, hidden eyebrows, and pencil-altered lips.

2025/10/30

Ghost stories told around a camp fire, visiting a haunted house or watching a scary film are all common Halloween activities. We clearly enjoy scaring each-other and feeling scared, even though it seems completely counter intuitive. There are a number of reasons for this, which we'll explore in the episode.

Could the AI bubble burst sooner than expected?

2025/10/29

In economic terms, a speculative bubble refers to a situation in which the price of an asset becomes heavily overvalued. An asset could be anything from company shares and property to cryptocurrencies. But eventually, reality catches up. Investors begin to realise the asset isn’t actually worth as much as they thought, confidence fades, and many rush to sell. When everyone sells at once, prices collapse, leading to what’s commonly known as a crash. But what exactly is a speculative bubble? Have

2025/10/28

We've all experienced that strange sensation of stepping out of the bath or swimming pool, and noticing grooves which have formed on the tips of our fingers. Have you ever wondered why that happens? It's not just because our skin absorbs water and swells up, as you might think. It's actually also down to our nervous system being at work, causing our blood vessels to constrict. So, what's happening is that the blood vessels in our fingers narrow down, making our fingers shrink in size, while the

Perfectionism is the tendency to set excessively high and unrealistic standards for oneself and others, and to evaluate one’s worth based on the ability to meet those standards. Perfectionists are not satisfied with anything less than flawless results, and they often fear failure, criticism, or disappointment but constantly striving for perfection can have serious consequences.

You’re no doubt familiar with IKEA as the king of flatpack furniture. But you may not be aware that the Swedish company’s name is also associated with a cognitive bias. It’s all to do with how we assign greater value to objects when we make or assemble them ourselves. Now that might seem counterintuitive but it’s become an established marketing tactic over the years. What was their evidence? Why on earth would we want to pay more for doing more work ourselves?
