Still, it's never too late to begin. Bones, like skin, deserve special care. Nothing could be further from the truth. Your bones continue to evolve and change throughout your life. However, at about age 35 for women and slightly later for men, bone density begins to decrease.
Many factors influence the processes carried on by bone tissue.
Other hormones aid in the release of calcium and the breakdown of bone mass. Third, there is physical activity. Bones respond to mechanical stress by becoming denser and stronger. If you walk a lot, for example, your leg bones will respond by increasing their mass. If you regularly use your arms to lift weights or swing a tennis racket, the bones in your arms will grow stronger.
