I'm so glad he's prioritizing his health/recovery. If it goes as predicted (in the sense of what we've been told about estimated recovery and rehabilitation time, and about the injury not being as bad as last year) then I do think Worlds is his next aim. I feel bad for him - like Brian has said so often Yuzu really just loves to skate, it must be so frustrating to be kept from it time after time. I think Yuzu has mentioned that it's limited what can be done for his injuries at this point due to not enough biological material being left to work on through surgery (sorry I'm having trouble saying that in English).
Retirement is such a hard thing to think about. Most of all his health is the biggest concern, especially if he wants to continue skating non-competitively afterwards and also just to live without much pain or many complications later on in life. No matter when it has to end, his competitive career will forever be legendary. But it was heartwarming when he declared he was not thinking about retirement yet, I think during the interviews after Rostelecom fs?
