Let’s admit the truth of life: some people always try to impress others. How do they do it? Typically, with the help of things. And while some objects can amaze with their uniqueness or unusual design or outstanding quality, a number of them take first prizes because of their ridiculously high cost. And you will never guess how much money exactly people pay to own something unique! For example, are you willing to pay $50,000 for an umbrella made of black crocodile leather? Or $48 million for a smartphone coated with gold or platinum and inlaid with a pink diamond? If you want to save a bit of money, there are cheaper models for you to choose from. For example, models with an orange diamond will cost 42 and a half million dollars. No comment.

Out of the nearly 500 different species of shark that inhabit the oceans today, only a dozen or so have ever been known to go after humans. And even in those cases, it’s only believed to have happened because the shark was confused or curious. So, despite what movies like Jaws or The Meg have shown us over the years, there aren’t any sharks roaming near the shoreline, looking for people to eat. In fact, sharks tend to prefer smaller fish and invertebrates. When it comes to us, it’s an old cliché but it rings true – they’re more scared of you than you are of them. Of course, everybody should know how to decrease the chances of encountering a shark. And if you happen upon one, here's what you should do.

There are many things that we think are the same, but they’re actually 2 different things. For example, when someone says, “I’m going to America,” they probably mean the US. Would you like to have a mug of coffee or a cup of coffee? Have you brought a mushroom or a toadstool from the forest? Did you have a macaron or a macaroon with lunch yesterday?

You've probably never thought how much the way you live on Earth depends on the size of the Sun! The Sun is a yellow dwarf: a perfect sphere of scorching plasma, generating a magnetic field 24/7. Despite being called a dwarf, its mass is 330,000 times bigger than that of the Earth! And the diameter of this giant is more than 864,000 miles! But what if it became a red dwarf? First of all, red dwarf stars are much colder than yellow dwarfs. So the climate all over the planet would be getting colder and colder, and it would become impossible to live too close to the North and the South poles. And quite soon, half of the planet would turn into an icy desert...

Today it’s difficult (if not impossible) to find a person without a phone. We take them with us everywhere, even in the shower and in bed. However, keeping your phone in some places can be really dangerous for your device and, even worse, for your health.

A study from the University of Exeter has proven that the electromagnetic radiation emitted by phones adversely affects the quality and quantity of sperm. The longer a man keeps his phone in his pants, the higher the risk! As for ladies, they aren’t safe either! Even though there’s still no consensus about whether or not cell phone radiation causes cancer, scientists recommend keeping your phone away from your breasts.

While most of us will probably never get a chance to meet the Queen, it couldn’t hurt to brush up on your court etiquette, just in case. No one wants to wind up being thrown out of Her Majesty’s dinner party, so you should remember the rules if you want to avoid making a royal fool of yourself.

When Marine Second Lieutenant Walter Osipoff was boarding a plane on May 15, 1941, he didn't know yet that the flight would almost become his very last. Shortly after the takeoff, an accident that no one could have predicted left the man dangling high in the air, tangled in his parachute and hanging from the aircraft's tail in midflight. It was another regular sunny morning in California, and everything was calm at the North Island Naval airbase. There were no warning signs to the drama that was about to unfold in just a couple of hours. His parachute's ripcord got tangled with the automatic-release cord of the cargo cylinder, and the next thing he knew - his parachute was deploying inside the plane!
