Ageing and exercise is a very interesting area of research.
The decline in muscle bulk with ageing is not inevitable but can be almost completely halted with exercise. I say almost as the body's sensitivity to insulin declines with age and is something you cannot stop.
(Insulin is also responsible for muscle growth as well as blood sugar control, which is why it is a banned substance in sport)
