I fear crashing really really bad. Like the kind that ends your ski career forever. Also, something off the subject, kind of. Hobojibber said that when you burn to death you actually feel all the burning, in reality this isn't completely true. If someone lit your clothes on fire or something, you'd surely feel everything, but if you were in a building that was on fire, you would suffocate first because the flames would use all the oxygen in the room to burn. In that case you wouldn't feel it. Suffocating would surely suck ass though.
If you are holding up a bank and your pants fall down, it's okay to laugh. And let the hostages laugh to. Because come on, thats funny.
