What do you think about extreme esports?

I think safe and full of adrenaline extreme sports are a huge energy waste. If i had the opportunitie to practice extreme sports i would love to do parachuting. I had always have the curiosity of living the free fall experience, of feel the wind in my face and hair and the view you can see in that perspective. But an etxreme sport I would never practice is kayak or rafting. They are very unsafe and the truth is that kind of adrenaline is not good for me.
I would like that sensation can be keeped in my memories forever, because it is a very unfrogettable experiencie. I alsio think that people who practice these kind of sports are in very good shape and have a big courage. I would like to do these sports for once in my life.
