Some people think that extreme sports help to build character. Others do not agree with them.
I support the first point of you. Firstly, extreme sport is a great risk, so it will make sportsman braver and stronger. Secondly, a person, who does an extreme sport, will feel freedom while doing something dangerous, so he would become less aggressive. Thirdly, extreme sports usually needs a person to be very active and physically developed, so the sportsman have to be hardy.
However, extreme sports have some disadvantages.
To begin with, while doing such kind of sports a person can get injured physically or mentally, so it can cause a fear of all kinds of sports. Furthermore, extreme sports can kill a person because it is very dangerous.
I do not fully agree with my counterparts. A lot of people after getting injured become even more interested and excited about the sport they do as they want to achieve goals they could not achieve before. To add, usually people, who try to do impossible things, die while doing their extreme sports, so if you do not turn off your brain while doing something, nothing bad will happen.
All in all, I think that extreme sport is a great chance to test yourself and see your abilities.
