Safety! I met several guys that were too cool for safety equipment when i was in shepard center with guys spinal cord injurys and having skin grafts done it not a pretty site. There was one guy there that was from out of state he did not like to wear a helmet either he now has a tramatic brain injury and has to wear a paded helmet 24/7 becase he is missing half his skull and is literaly a drooling zombie. I spent 3 months there and It was a huge eye opener. Sometimes death is not the worst thing that can happen to you!
