What do you think about extreme sports?

I think there are several extreme sports, well I think most will produce adrenaline, a feeling is very strong.
But I think care should be taken with extreme sports, because something can fail, and that perhaps it was a fun can turn into a serious accident. Well there are several types of extreme sports, some who practice in the air, like the others that are practiced in the water.
To me in particular I like extreme sports, I think you used to take away all those bad vibes and stuff, well I prefer between the extreme sports that are performed in the air, I get more attention.
