Answer 2

As you age, your body may reabsorb calcium and phosphate from your bones instead of keeping these minerals in your bones. This makes your bones weaker. When this process reaches a certain stage, it is called osteoporosis. Many times, a person will fracture a bone before they even know they have bone loss.
