If you look at pretty much every actor, like Jack Nicholson, DeNiro, Tom Hanks, John Travolta, they all gained weight and became large when they got into middle age, but when they were young they were very trim and athletic. I know it is hard to lose weight when you are older because the metabolism slows down, however it can't be impossible. Is there any way to lift this curse? For example if those actors I mentioned were to diet and exercise harder, would they look like their old selves? One of my goals when I become in shape, is to stay that way my whole life, and not become like them.
