About 10 years ago I was in an automobile accident. I rolled my car 4 times and came out with only a seat belt bruise and a torn left ACL. I spent months in physical therapy both before and after surgery. In the meantime, I really learned how to fall and not get hurt.
Just now I absent-mindedly managed to fall off my deck (about 2 feet). I realized I was going down and not to fight it. There I was, laying on the ground and my daughter is asking me if I'm OK. "Yeah, I'm fine. I rolled." You know, that's a nice skill to have.
