Well, I think its more of a personal belief. You have decided its not worth the risk. I have decided it can be worth the risk in few situations. People take risks all the time for their own enjoyment... its a part of enjoying life. If I lived my life not taking risks, then I'm not really living anyway. I decide for myself how far those risks go... you wont ever see me riding on a motorcycle ect... but you also won't see me racing around other people that have not accepted the risk.
