Extreme sports

It is thought that extreme sports are dangerous but as far as I'm concerned, I think it is a matter of courage. Practicing sports gives you the oportunity not only to get a goal, but also to keep fit. Most people face the daily problems as if they were practicing a dangerous sport. I stopped practicing these dangerous sports because I wasn't strong enough to bear the tiredness. Although I like them, it doesn't make sense to join if you are afraid of heights or depths, besides, neither I have time enough to join a sport center nor money enough to afford it.
