Extreme sports

Extreme sports are those sports or leisure activities and sports that involve somecomponent of a real or apparent hazard or extreme difficult conditions in whichthey practice.
Under this concept brings together many existing sports that involve a certain amount of physical demand and above all, mental. They include the most demanding sports in the hiking (ice climbing, rock climbing, etc..), And othernewly created as (bungee, snowboarding, parkour etc.). A sport, not considered extreme, can be defined as well if done under special conditions or unusualcircumstances in the. For example, rock climbing a few inches of soil (boulder) is not considered "extreme sport", but if done on a vertical rock wall several hundredmeters, then it is applied to the term.
Can be considered as a person practices an "extreme sport" when it does first.For example, the decline of a class IV river is pretty extreme for those who neverbefore had risen to a raft and you will feel it as far above their abilities.

Opinion
            I have practiced very few extreme sports, but one thing I love about this sportthan others. In an extreme sport you feel like you're doing something puts his life at risk even if a lot of protection or the insurance, but it feels more emotion q if one were making a common sport. The difference for me is that a sport is more common to see who is better in this sport, and one end carries his body up as much as you can do.
