Oksana Chusovitina has shown that even at her advanced age in a sport ruled by participants nearly half her age, that she is still competitive and deserving to be on the Olympic stage. She shows the world that not all athletes fit into a specific mold and as long as you can compete you should. Never let anyone tell you that you can't do something, and aim for the stars.
There is no reason for this woman to retire. She's still in shape. She's still competing, and it's not like she has a festering injury that prevents her from doing her best. She should keep going until she doesn't want to do it anymore. Some may disagree, but I think some people start to rejuvenate when they reach a certain age.
At the age of 41 she is still fit enough to have got through the qualifying rounds at the Rio Olympics, competing against women more than half her age. She should only retire when she feels that she can no longer compete. This has nothing to do with her age and everything to do with her personal health and level of fitness.
I see absolutely no reason to encourage the 41-year-old gymnast who is actively proving that age is just a number to retire. The fact that the athlete is competing in her seventh Olympics is remarkable. The fact that she has a chance to make the vault final is undeniable proof she is still valid.
