during travel, you contact people of different regions, see new locations, observe various cultural activities. Thus you get direct knowledge as against indirect and remote knowledge derived from sources like books, TV or internet.
By travelling we experince lots of things. We view lot of people around.We don't learn much ,but just watch the poor people as we pass the villages and rich people in big cites. We get to know various thing,what happening around the our world.
Travelling widens one's experience and knowledge about life and it also breaks the monotony of busy life. It also provides the opportunity to the traveler to compare about different things in different places. I prefer travelling with friends and family...!
