In what sense? Do you mean sense of balance intellectually or physically? I would hate to lose it either way. I have had labyrinthitus and it was horrible so if losing my physical sense of balance would entail dizziness, I wouldn’t want that. I’ve lost my sense of balance politically but I think that may have been the right thing to do.
My sense of humor is integral to who I am; I can’t imagine losing it. And while I can imagine being able to cope with being congenitally blind, I would hate to lose my eyesight at this point.
So I guess I’m not prepared to play this game!
