Do you really know? ·

2026/03/15

According to recent data from personal finance website NimbleFins, the average British family of four spent around £4,678 for a 9-night holiday abroad in 2023. And of that total amount, £1,828 went towards flights, nearly 40%, reflecting the reality that air fares still account for a high proportion of the total cost of a holiday. And experts say that flight prices are set to continue rising in the coming years, as more expensive sustainable aviation fuels are brought in to replace traditional

Do you really know? ·

2026/03/15

Whether it's for the sake of comfort or maintaining good hygiene, many of us opt for taking a shower on a daily basis. Studies have shown it's the most popular shower frequency. Some swear by the virtues of a refreshing morning shower while others like theirs in the evening when winding down and getting ready for bed. But in actual fact, our bodies are pretty adept at self-cleaning. For instance, dead skin cells shed completely naturally! If you're someone who showers more than once a day, you may

2026/03/14

When it comes to what proportion of people speak more than one language, estimates vary but the general consensus is that at least half of the world’s population do so. If you're bilingual, you may well have encountered a fascinating phenomenon: that a new personality seems to emerge when you switch languages. In March 2017, Quartz ran an article on the subject, written by Nicola Prentis. Prentis included accounts from a number of multilingual people, including Margarita, a Russian-American

Is living by the sea better for your health?

2026/03/14

I don’t know about you, but I find that there’s something about the seaside air which just always makes me relax and puts me in a better mood. As it turns out, that might be more than just my impression. A study conducted by the University of Vienna and published in May 2022 established that living near the sea can have significant effects on health and life expectancy. Now the idea is not exactly brand new. Way back in the 17th century, English doctor Robert Wittie published a book entitled

2026/03/14

The Green Belt is a policy for controlling urban growth in the United Kingdom. It refers to a ring of countryside where urbanisation will be resisted for the foreseeable future, maintaining an area where local food growing, forestry and outdoor leisure can be expected to prevail. The Green Belt policy was first introduced in 1935 by the Greater London Regional Planning Committee, and now covers 14 areas of land around the 16 largest urban cores of England.

Why is sugar bad for our memory?

2026/03/13

We're well aware of its negative impact on our waistlines and heart health, but sugar also takes a toll on our brains. And it's not just found in the obvious sources like refined sugar from sugarcane or sugar beet – it's lurking in fruits as fructose and in dairy as lactose. Back in 2015, the World Health Organisation released guidelines recommending adults and children “reduce their daily intake of free sugars to less than 10% of their total energy intake”, to remain at a healthy weight.

At what age do we really become adults?

2026/03/13

In France, adulthood starts at 18. In some countries, it’s 21. It all depends on the legal age of majority. But that line is mostly legal and science tells a more complex story.At 18, the brain is still developing. In particular, the prefrontal cortex at the front of the brain and the cerebellum. A 2009 study in the Journal of Adolescent Health shows these areas are crucial for emotion regulation, responsibility, planning, prioritization, and impulse control. But then, is it really possible to

2026/03/12

We all know that exercise does wonders for our bodies. But what might come as a surprise is that it can even bring us to climax, at least for women. Now, that might sound a bit far-fetched, but it's actually true: achieving the ultimate pleasure during a workout is possible.According to Medicalnewstoday.com, renowned sexologist Dr. Alfred Kinsey was the first to document instances of coregasms, noting links between orgasms and exercise in his 1953 book Sexual Behavior in the Human Female.

At some point, we've all probably come up with some flimsy excuses to avoid a night out, a fancy restaurant dinner, or hanging out with friends. Sometimes it's just a lack of enthusiasm, while other times, it's because our wallets are feeling a little bit light. We all know that leisure activities can put a serious dent in our finances, and when money gets tight, we can end up in a real financial mess. Right now, there's a trend making waves on TikTok called loud budgeting, where folks openly

Imagine a virtual country where women come together to push back against misogyny and celebrate female empowerment. Born on French TikTok, Tanaland has captured the imagination of over 18 million women who envision a world free from patriarchy and judgment. Tanaland is a fictional, women-centered country that has emerged as a satirical safe haven, inspired partly by the 2023 Barbie film starring Margot Robbie, which promoted themes of gender equality and female empowerment.

2026/03/11

We spend a good deal of our time at work, 35 hours a week or more. It's an integral part of our lives, so if you can it's always best to surround yourself with good colleagues. They make work not only more enjoyable but stimulating. Their support and collaboration also helps to create a positive environment where teamwork leads to tackling problems and finding solutions. However, when we don't get along with our co-workers, time moves slowly, worse still is when you find yourself compensating for

2026/03/11

According to the NHS, around 1 in 3 people in the UK are affected by insomnia, and it’s particularly common in older adults. Many people turn to medication like benzodiazepines in an attempt to address their insomnia. Now these generally help, at least to begin with, but they tend to bring less restorative sleep. And if no other changes are made to daily habits, there’s a good chance the insomnia will return once the medication is stopped. What other options are out there then? So how does one

What is xylazine, the so-called zombie drug?

2026/03/10

In July 2023, the White House recognised that the United States was facing a “grave threat” in the form of a highly addictive drug called xylazine, introducing a six-point plan in response. Dealers mix xylazine into supplies of fentanyl, itself a dangerous drug which kills thousands of Americans each year. The street name for xylazine is “tranq” or “tranq dope”, but it has also been called the “zombie drug”. What is it made up of? Why did people name it the zombie drug? Has it been seen outside

Caring for yourself involves more than just tending to your nails; it's about making sure they're well-groomed, especially those on your toes. Trimming them properly is also key to avoiding painful ingrown nails, but on the other hand going overboard with your clippers can cause problems too. So let’s discuss how to find the right middle ground. According to the East Sussex Healthcare NHS Trust, the best tool for the job is either nail clippers, which are lever-style cutters, or nippers, which have

Why don't prices fall when inflation slows?

2026/03/10

Inflation peaked in 2022, but now it’s on a slow and steady decline, reaching 2.5% in June 2024, down from 5.5% in June 2023. Plus, some commercial practices that drove prices up are now better controlled. For example, since July 1, 2024, supermarkets have to label products affected by shrinkflation—where they reduce the quantity but keep the price the same. But even with these changes, you’ve probably noticed that supermarket prices aren’t dropping. And actually that’s totally normal. Why has

If you’ve seen more and more people out wearing roll-neck jumpers, vintage blazers or cross-body bags, you could be forgiven for wondering if you’d travelled back to the 19th century without realising. But actually the poetcore aesthetic has been on the rise for some time now, to the extent that at the end of last year Pinterest identified it as one of its “Pinterest Predicts” trends for 2026.

Are electric toothbrushes really more effective?

Do you really know? ·

2026/03/09

Electric toothbrushes come with a head that makes small circular movements automatically. Studies have shown that, for the same amount of brushing time, they can remove up to twice as much plaque as manual toothbrushes. They also help reduce the risk of gingivitis, gum inflammation, and bleeding. However, some electric toothbrushes can be too abrasive on sensitive or weakened teeth, as not all use the same technology. It also depends on how you use them. Improper brushing can lead to dental
