I don't think anyone has called for Tuktamysheva to retire. Voicing concern that she may be staying in skating because she doesn't have anything else planned in response to her direct answers in an interview is legit, IMO. And it should be familiar, because how many of us are in jobs and/or professions because we don't have a plan to do/train/transition to something else?
I've long loved her, so I hope as long as she wants to skate, she does, and I get to see her.
And if we can support Menshov into his 30's -- he only retired because of a shoulder injury -- I don't see why Voronov needs to go anywhere.
