No, I do get how he meant it but honestly? Not that easy!
It's not like you can pick any other T and be fine with it. It takes time to find another fit and to adjust plus there will be a period of mourning the RS.
I think you two should discuss the possibility of him retiring. I think it's better to know it in advance so not to be blindsided. Personally, I'd like to know in advance to be able to transition slowly to another T.
