Answer 2

The bones of old peoples become weak due to absence of calicium(Ca) in their bones mostly it happens after 40 years of age.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.
