In my opinion, sport is an important part of people's lives. It helps to temper not only the body but also the spirit. And I consider unacceptable ban on violent sports.First for many a sport like boxing for example, that's life. Boxers specially trained in boxing and now earn a living. If they take this way to earn money, not known if they survive at all.Secondly, these sports can be seen as a way to get rid of aggression and stress. In order to get rid of negative emotions, simply to throw out their anger on the punching bag. On the other hand, a sport like boxing can cause serious injuries to people. Sometimes it is very serious consequences. However, serious damage to the health of the body can be applied to absolutely any kind of sport (except for chess of course), so I think there is no point in banning the violent sports.
