I have problems with the general tendency of always minimizing risk. When did risk become something to avoid at all cost? Follow that path and you end up avoiding everything that makes life worth living. It's not about whether you should wear a helmet on a bike. It's about accepting the fact that you are going to die and stop worrying about it and start living.
I don't want to die but I'm not going to let the risk of dying get in the way of living. BTW I wear helmets when skydiving and riding my motorcycle :)
