When you think about it, our bones have a pretty thankless job. They carry us everywhere, give us tireless support, and supply our blood with important nutrients. In return, we tend to ignore them.
T hat's a bad idea.
If we don't pay attention to building and maintaining strong bones, they can become thin and weak over time. This process of bone loss, called osteoporosis, makes bones much more likely to break. Bone loss is a serious problem for many older people, especially women. But to a great extent, such loss is preventable. Bones become so brittle that even a minor injury can break a wrist, hip, or spine.
