If you consider his age and how little he trains compared to many top skaters, it truly is impressive how technically strong he is. Amazingly talented.
Regarding his future, I, too, worry about body changes (and his asthma), but my gut (OK, my hope) is that his impressive abilities will survive mostly intact. As for how he will handle presentation and artistic growth, I am rather confident that he'll be able to handle the artistic side of this level of skating quite well, because I think that's the kind of person he naturally is. Of course, this season will tell us much more about what the future holds for him.
