Have you ever thought of what it would be like to lose all your teeth? Let's imagine you’re a famous actor who stars in exciting action and adventure comedies. You have millions of dollars and millions of fans. It’s cool, but you want something more. You want serious roles and acting awards. That’s why you decide to play a character who has lost all of their teeth. And to better prepare for the part, you choose to remove all your own. But how can having no teeth affect your digestion? Well, a smoothie diet can't replace regular food. Your stomach will be struggling to get vitamins and have digestive issues. Dentures help chew, but they put pressure on your gums. Besides, food particles fall behind and underneath the dentures and irritate your entire mouth. The dentures don’t weigh much, but it’s enough to make your mouth feel tight. And the worst thing is you can’t taste the same as before. Your palate also has taste buds, but now it’s blocked by the dentures! Your body is losing energy every day, and your immune system is weakened...

Do you love incredible stories of animals saving human lives? Well, then this one will definitely amaze you. In the fall of 1924, Curtis Welch, the only doctor of the port town of Nome in Alaska, raised the alarm: there was too little of the cure for a sudden illness striking the town. Dr. Welch ordered an additional batch and was hoping to receive it before winter because otherwise the town would be locked out by ice for 8 months. But the ship with the cure didn’t make it in time, and the town had no choice but to wait until spring. There were no signs of an outbreak in Nome, but Dr. Welch was still beside himself for some reason. In December, he took in several patients with a sore throat, and although he ruled out the illness, his suspicions grew with every passing day. Until finally, in January 1925, they turned out to be correct: he officially diagnosed the first case. Nome was home to about 2,000 people, but 10,000 more lived in the surrounding area, all at risk of contracting the illness. Over a million units of the cure were found across the country and shipped to Alaska. But the real challenge was to get them to Nome itself...

If you spend only a day at the gas station, you can see just about everything. The “get every last drop in the tank” types, the nozzle tuggers, the nozzle ripper-offers! And possibly even a few near explosions! So today, we decided to spread the most common mistakes people make while fueling up! For example, do you remember that thing about static electricity igniting invisible fuel vapors? Well, get this: when you get out of the car, your clothes sliding against the seat fabric creates some static charge. And when you grab that metallic nozzle, a spark can happen. That tiny spark can light up those gas vapors!

With high-speed rail, traveling by trains often turns out to be faster than by car or by bus. Very often it even results being faster than flying. But what if trains could transform into planes? Imagine a plane landing at its final destination: its wings come off, it's set on a railway track and becomes a train. Could this time-saving dream become a reality any time soon?

Human body is a fascinating mechanism where every detail matters. In the course of evolution human body becomes more advanced and gets rid of items it no longer needs: like a tail. Several hundred million years ago our ancestors used tails for swimming just like fish. Wouldn't it be cool to have a tail? Let's find out why exactly we lost them.

There’s so much going on in airports and on board the planes that you don’t need to bother learning it all. But there are things you do want to know — yet no one will tell you about them. Do you know, for example, why if you get off the bus and step away too much, the ground crew might ask you not to walk under the airplane wings? Or what a ‘decision altitude’ is? Or what is a reason you won’t ever see an elderly person or a child in the emergency exit row? Wanna know those and other secrets? Here they are!
