Assuming isomorphic change, the stress in your leg bones increases as you grow larger.
Explanation:
As the body grows or enlarges, the shape of the leg remains the same, though the area increases, but at a very low or minimal rate as compared to mass or size. So, the mass of a person increases more, than his body area. If height doubles, stress also doubles.
Assuming isomorphic change, the stress in your leg bone REMAINS THE SAME as you grow older. Isomorphic change means a corresponding or similar change. As one grows older, the stress that exist in the leg bones has a way of changing with the growth and the development of the living organism, thus remaining constant at the level that is comfortable to the living organism at all time.
