As a person ages, the body undergoes many changes. Besides visible formation of wrinkles and graying of the hair, a person also experiences reduction in the muscle mass as well as loss of strength in the limbs. The bones tend to lose their density due to calcium loss and this can cause the person to stoop. All these changes due to aging can affect the person's movements, coordination as well as balance. However, these undesirable effects of aging can be minimized by doing exercises.
