Do you really know? ·

2025/11/28

On paper, fish have everything required to be an excellent staple to many diets. They’re rich in protein, vitamins, trace elements, long-chain omega-3 fatty acids, and aren’t too high in calories. The only downside is that fish live in an increasingly polluted environment. What with heavy metals and plastic waste invading the oceans, more and more people are concerned about the pitfalls of eating fish. After all, they can be contaminated by chemical pollutants such as PCBs, methylmercury, or

Most of us never really forget the person who first made our heart race or that awkward, wonderful, or maybe disappointing teenage kiss. Whether it was magic or a mess, that first experience often leaves a mark that shapes the way we see relationships as adults.

2025/11/27

On average, we remember just one dream per week, and around 5% of us never remember any. But in reality, we all dream; it’s just that some of us never have any recollection of doing so. So why is it then that certain dreams stay with us, while others fade away immediately?It’s important to be aware that over the course of a night, we go through various phases of slow sleep, including deep sleep and REM sleep which is short for rapid eye movement sleep. A new cycle begins around every 90 minutes

Why do we drive on the left hand side of the road?

Do you really know? ·

2025/11/27

According to the AAA Foundation for Traffic Safety, there are as many as 430 deaths per year due to wrong-way crashes in the United States alone. That might be hard to believe as for most of us driving on the “right” side of the road is as automatic as brushing your teeth. But there is of a course a divide between countries that drive on the left and those that drive on the right. In ancient times, driving was not really regulated, but it was nevertheless the norm to drive on the left. And it’s

2025/11/26

An often cited estimate suggests that children smile an average of 400 times per day, while when we reach adulthood that figure drops to just 50 times, even for the happiest of us. For most adults, it’s more like 20 times. Now of course most of the time we smile involuntarily in response to something bringing us joy or making us laugh. But it’s also possible to smile intentionally, which can actually bring on a whole host of health and wellness benefits. What are the health benefits of smiling

Why do men often wake up with an erection?

Do you really know? ·

2025/11/25

A lot of people think that morning erections are triggered by erotic dreams, or a need to pee, but in fact they're a physiological reflex linked to sleep. That’s right - they’re not dependent on sexual arousal at all. And in a somewhat similar way, women actually also experience increased blood flow to the clitoris during the night. Now, the scientific term for a nighttime erection is nocturnal penile tumescence, or NPT for short, and men get a few each night on average. They occur during REM

2025/11/25

It is a bit of a stereotype that the Brits love to moan, with the weather and Brexit being among the most common causes of grumbling around the country. It might not always be pleasant around someone who’s complaining, but there is something deeply authentic about it.

That’s right; venting allows you to release pent-up emotions, which may relate to something that’s been

It refers to the sense of having already seen or experienced something you’re confronted with, even though you know that you have never actually seen it before. For example, you visit a new city for the first time in your life, but at a precise moment you get the feeling like you’ve walked down a certain

Sex is generally synonymous with pleasure, but sometimes it can bring on headaches that are unpleasant at best.

2025/11/22

When it comes to health, it’s clear that gender differences play a significant role. It's now recognized that the occurrence of diseases, their onset age, symptoms, severity, and even responses to medications differ between men and women. The question of whether men and women perceive pain differently has been a topic of scientific discourse for quite some time. It’s an important matter too, as it could influence whether treatments should be tailored based on gender. For now, current studies
