Various posts on this site have been about body hardening. Some claim that repeated light strikes to shins, forearms, hands, feet, etc, allow for more bone growth and callouses to develop, thus hardening the body. Others say that these light strikes, over time, deaden the nerves, so one feels less pain when striking or blocking. It seems that more talk about the bone formation, but what about the nerves? It seems to me that thickening the bones, even developing calluses, would not be permanent unless continued indefinitely - that over time the body would reabsorb the excess bone, since bone is constantly being formed and reabsorbed to fit the body's needs. By contrast, I would assume that damaging the nerves would be a permanent act, and while it wouldn't leave the body any stronger structurally, it would lessen the pain felt when force is applied to the "hardened" bone. I am not saying that either one is not true, just looking for clarification. Thoughts?
