Well once you're that age, it becomes a lot more difficult to keep fat off or to burn it. It can be done. But as compared to being in your teens and 20s, it becomes much more difficult to stay in shape, it takes a much longer time to get there. That's what I meant.
Michael looks fit to me. He doesn't look frail. His build is naturally slight, but he looks tight to me. Nobody here knows if he's in good shape or not, you'd have to see him without his shirt on or something. But it's just as silly to say he's not fit as to say he is, I suppose. But his body, from what I can tell, looks tight to me. People thought he looked frail in his 20s too, but he was in awesome shape.
Madonna is in better shape now then she was in her 20s, but she looks like a man, so... lol.
