1. The same food tastes different in the plane and on the ground. When the plane gains altitude, taste receptors change by about a third. This is why many airlines add salt and various spices to their menus.
2. The white streak left behind by a plane in the sky can be used to predict the weather. The thickness of this line can indicate high or low humidity in the air. A very thick streak may mean a storm is approaching.
3. Money spent on travel makes people happier than money spent on material goods. After the first day of travel, people's stress levels drop by 89%. During travel, you forget about all problems, and stress levels significantly decrease.
4. Travel is used in the treatment of depression. Psychologists use this treatment method with patients suffering from depression.
5. You cannot open the airplane door when it is in the air. Even if you manage to do so, you don't have to worry about everyone being sucked out of the doors (as we often see in movies). When the plane is up, the doors are designed in a way that the air pressure presses on them, making them completely safe. Even several very strong people cannot open the airplane door.
6. During travel, you become more creative. According to research, people who travel regularly can find more creative approaches to solving various tasks.
7. Those who travel become smarter. It's simple, like with books, the more you read, the more you learn. Visual memory works the same way, and you learn a lot of new things during vacations.
