When it's all said and done, you have to use your own judgment. If you decide wrong, it'll be you that gets run over, not anyone else.

Just doing it until you get used to it may "work". But the problem is that getting used to danger doesn't make the danger go away. Steelworkers and mountain climbers get used to heights so it doesn't bother 'em at all, but they still get killed or busted up on occasion, too.
