I'm a huge Yuna fan, but even I don't believe she has a superhuman body and boundless motivation. She'll be 27 by 2018. It's doubtful her body will allow her, and let's not even talk of motivation. It took a long time of soul-searching after Vancouver before she regained her competitive fire. After Sochi, I can't imagine her wanting to go for it again.
Well, Kostner will be 27 in 2014. Is she calling it quits now and not going to Sochi?
