No, I love hights, I love pushing the envelope. I used to put myself in dangerous situations on purpose to push myself to see how far my fears would let me go. A fun exercise if you don't mind the risk.
My activities included free face rock climbing, skydiving, bungee jumping, white water rafting, and race car driving. Not to mention some very dangerous jobs I took on.
I think fear, and the fear of death makes you feel more alive than any other time.
