The extreme sports

There are so many kinds of extreme sports. For example, bungee jumping, rock climbing, surfing, skiing, base jumping, parachuting, parkour and winter swimming.
There are lots of people afraid of doing the extreme sports. I think it needs courge to do them. If you can overcome your fear and do these sports then you will find out there's nothing you need to scare of. For example, I want to do the bungee jumping if I have a chance.  Most of people are afraid to do this if they can stand on the jumping platform then jump. That is a very awesome thing.

There are more and more people do the rock climbing. Rock climbing is a physically and mentally demanding sport, one that often tests a climber's strength, endurance, agility and balance along with his mental control.  There are some styles of  rock climbing. for instances, aid climbing, traditional climbing, bouldering, free climbing,free soloing, indoor climbing and etc.
But I think I will never do the rock climbing because it looks very danger thing. Climber use some equipments like rope, cord and webbing. Although we have these equipments, rock climbing still needs strength, stamina and the determination to never give up.
