I am, perhaps foolishly, not really worried about accidents. He is generally very coordinated. His injuries come from being foolish. Cracked his pelvis as a teen from trying to do a kick beyond his abilities at martial arts class. Tore his shoulder when we were horsing around and I pounced on him. Broke his foot by flipping over me, out of the bed, but not sticking the landing (foot met siderail instead of floor). Anyway, you are right, we will have to be aware of that. I will remind him of that danger .
