These skaters are athletes who work so hard with high cost in every sense and usually make less money than the athletes in other sports do. Long live this highly dangerous, demanding, dirty, political and beautiful sports!
I think Yuna already has had quite a long, splendid career which will be long remembered even if she is never to come back to the competition from now on. Selfish me wants to see her bring 3 loop back to her program and have a bit more (slightly) pointed toe because I am sick of hearing those oexcessive, constant criticism by her naysayers. However, how long she will compete depends soley on her decision. She could do anything that she wants to do and I hope whatever decision it is, she will lead a happy and healthy life.
We who are fans are thrilled with any skating time YuNa gives us, but if she stops tomorrow for any reason, we still have her amazing past achievements. Dick Button always says that a great skater leaves skating better than it was before he/she got there. YuNa certainly fulfills that requirement. She has brought skating to a new level because of the quality of her work, not just her jumps, and she has also changed the skating scene in Asia in general and in Korea in particular. YuNa is so unusual in every way and such a gift to skating that even people who aren't fans of hers ought to see her place in skating history and respect her for it.
Like you, I hope that she leads a happy and healthy life, and like you I selfishly hope that she spends a long time leading that life as a skater!
