Well, I doubt it too, but then again I don’t think it would be the body issue. I think she has already achieved the top of the achievements, the gold medal at Olympics every sportman/sportwoman dreams about, and it would be extremely hard to find motivation to do it again. And if there is not enough motivation, of course her fitness would not be the same. But her fitness could be worked on if there was motivation. So it doesn’t really get it down to whether she could do it with this body, but would she want it enough to do anything to win, including whip her body back to competitive shape. But do you blame her that she is not that keen? The pains, the stress, the sacrifices, wasted time and money that she could be spending by doing something enjoyable, all the rigid schedule full of denying herself... and all that for what? She can’t do better than last time, there is no higher place than gold, so all that just to match or do worse than the last time?
