People seem to think helmets only save lives. They also can save you from a lot of other less drastic situations than death. Talk to the people who were wearing helmets when they crashed that are now alive but have any of a HUGE number of neurological issues, equilibrium issues, vision issues, neck problems, back problems, etc., and I guarantee every one of them hates their ongoing medical problems but are thankful they had their helmets on when they crashed.
Oh, and not only am I the founder of the helmet hair club for men, I'm also a client.
