me? not at all... I used to be a pro-am freestyle skiier... no fear there and no cage.
After bombing 50ft cliffs and landing between trees, rocks etc every day you lose the fear until something happens that stops you.
A few of my mates had serious, serious injuries (talking broken spine, full facial reconstruction etc) and then stopped, but until it happens to you, you never learn.
I ended up leaving the sport due to politicts and the fact that the coaches took all the fun out of it.
This is the reason that I have never bought a motorbike.
I have a very blurred line when i'm close to the edge and I always step over it because I am so used to being able to bring it back. If I had a bike, I know I wouldn't be here now
