Well its good to see that most people on here have a fairly balanced view of things.
I really struggle with do gooders who preach about dangerous activities yet can't see it when they do it themselves in a different context.
Its hard to interpret what is or is not dangerous as everyone's perception of danger and risk is different.
In my time i have found it acceptable to jump off bridges, kayak over waterfalls, ski and snowboard in back country avalanche risk areas and at times ride my bike at 150mph...
but to me, although there is a risk, i accept it ,whereas many others would (and do) think I am completely insane!!
:P
