Travel broadens your mind
That is very true. This is the reason why people travel. People travel to learn something about other countries and nations and learn other languages. We visit the most famous places that we learned or read about. We travel because we want to know more about the world, other coultures, religions, nations.
Different nations travel for different reasons. It is said that Poles travel to earn some money. They just work abroad. Americans for example travel to take photographs of famous places. I think no matter is a reason, the most important thing is that we know more and more about other countries and people.
