I have a fascination with this kind of stuff. Taking risks is sometimes necessary and worthwhile in life, but seriously, risking your life just so you can say you realized a specific feat is really dumb. Especially when we have the technology to do the thing just fine with no problem whatsoever. I think those people live too comfortable lives and try to feel something. They could apply those skills to some meaningful work, but of course it doesn't get the same recognition.
