Bones are living tissue, like skin or liver. There are many, many living cells within a bone that are devoted to laying down and also to removing the calcium that provides the physical support that makes bone stiff and strong. If your diet is low in calcium, your body will take calcium out of the bones to use it for essential work elsewhere. If you don't use your bones, by exercising, the cells in the bone will take calcium out of the bone in a "use it or loose it" sort of feedback loop. When bones loose calcium, they are more likely to break or compress. So, when your bones are strong it means your diet and exercise are good and your bones will be much less likely to break or hurt.
