I just checked the motorcycle crash rule book, apparently it is possible to crack your bare head open even in a low speed crash. I think it has less to do with speed than it does with smashing your head on something very hard like the ground. I could be wrong. When I was a kid I once had a teacher yell at me for balancing a chair on two legs, I told him I can't bust my head open because I'm not even moving. He seemed to disagree. ; ^ )
My two cents. I say do whatever makes you smile. I am a risk taker and someday one of the risks I take is going to take my life. I'm fine with that, I would much rather leave this shitty world doing something that I enjoy than of old age or at the hands of some street punk. Indian Larry lived and died doing what he loved.
Gary Busey hit his head in a low speed crash and survived. Need i say more.
