The thing is, Nathan has made it very clear about how important education is to him and his family. As much as he loves skating, in terms of his future, he sees his education as priority. He has also said before that skating and going to school at the same time is stressful...so, unless something has changed in that regard, I think it's likely he will not be continuing to skate after the Olympics season. I think this will be true, even if he doesn't win gold because he has said before that he's happy with his achievements so far and that whether he gets a gold at the Olympics or not won't define him. Most likely, he'll drop skating to focus on finishing school no matter the color of his medal. Sure, there's always a chance that he can come back, but I don't think the chances are that high simply because of his ambitions with his education. It'll depend on what he decides to do with that. If he goes beyond a 4-year degree, he'll be in his mid to late 20s when he accomplishes that. Really, what are the chances that someone is going to come back to competing when they're that old? Don't most skaters start thinking about retiring around that age? I don't think that tennis and figure skating are that comparable. One could probably play tennis and compete for a long time but, for skating, it'd be more difficult simply because of the nature of the sport. Nathan isn't going to be able to jump all those amazing quads at his current rate and level of consistency indefinitely(though I would love for him to be able to). I would love to be wrong and I wish the guy could skate forever. Anyhow, the best thing as fans, I think, is to simply enjoy the moment and to share in whatever joy we still can with him.
