It’s a fact of life: As we get older, our bones tend to get weaker, and the risk of fractures and other bone injuries threatens our mobility and diminishes our ability to live full, healthy lives. It’s a growing challenge especially for populations such as ours in the United States that are both aging and living longer, to avoid the cycle of decline that comes with bone breaks and immobility that in turn results in even weaker bone and greater risk of fractures.
