Past a certain age, the body will also grow wrinkles and lose muscle
strength. That's optimal because regenerating the skin, muscles (and
tendons, etc) is too energy-consuming. And then, the body will decide
that the heart and the lungs need to rest, so it will cease to breathe
and pump blood in the vessels. Soon after, it will realize that the
cells are better off when recycled by other living organisms (worms
and bacteria).
