Plushenko has spoken about wanting to open up skating schools in Russia where students can also live and study. And he doesn't rule out coaching either. But he loves to skate and compete and has no desire to stop yet. Is there something wrong with that, for someone who has been a figure skater all his life and is still earning respectable results (when healthy)? Of course I am concerned about his body, but I think he is smart enough to respect his limits.
I'm sure he has never lost a wink of sleep over Yagudin's opinion of him either.
