I hear ya Mike. Made myself lame back in the dirt bike daredevil days. Drifted on a hundred plus foot jump, got a lucky bounce and missed the trees, but hit the ground hard. Split my helmet in two, head inside helmet so, so. The dirt bikes we had back in the seventies were heavy, and didn't have the suspensions that modern dirt bikes have, and when you tangled up in one, you tangled with something that would hurt you bad. I wiped out doing stunts dozens of times, fractured spine, broken leg, broken arm, broken ribs. Did it all sober, so don't have that excuse. My friends called me crazy, my Dad called me stupid. They were both right. Now the only adrenalin involved sport I do is bow building, and when something bad happens, the only thing that gets hurt is my feelings.
