This factoid is related in part to my Hospital Chronicles series, but not directly. I haven't had any serious injuries for a few years, but growing up, and in my twenties, I had my fair share of mishaps. I was trying to count, and near as I can come up with, I've broken or fractured seven different bones over the years. Some were from stupid accidents (punching a wall), others from bad luck accidents (crashing while skiing or slipping while hiking.) There's a chance I might have fractured one of my ribs once, also, but I never had it x-rayed so I'm not counting that in the breakage total.
I suppose I've been lucky (if you can count it as luck) in that I've never needed surgery to repair/set any of the injuries. Since three of the bones I've broken were in my left hand, I suppose that's rather fortunate. One chiropractor I went to took some x-rays of my neck and back and said I had at some point in my past fractured a vertebrae in my neck. If this happened, I don't know when, and it must have been not too severe of an accident or I would have remembered it. I'm not sure I trusted his evaluation (he was a chiropractor and not a radiologist, after all) but if he was correct, then I was very lucky. Any spinal cord damage from such an injury could potentially have paralyzed me from the neck down.
