The art of self defense is very old. It started in Asia, in the Far East. But other nations also knew it. Today it is very popular because it appears in many movies. Especially the films with Bruce Lee made it well-known in the whole world. However, the people know it but they do not practice it. It is bad and we must do something to popularize it. It is good to know the art of self-defense because it makes you stronger; it teaches you discipline and dexterity. The people should learn it from the beginning of their lives. That is why children should learn it in schools.
