For some reason that was the one physical part of aging I feared most. An innocuous bit of stretched out flesh. For years I've quiets run my finger under my chin, checking for sag. I'd always said that this was the one plastic surgery I'd undergo - that to me was the anti aging line I was willing.
I still check my chin on a regular basis. It's reflexive. Almost unconscious. My cheeks too. Just to see if the droop is growing.
So far it's only in my head. But I suppose eventually the waddle with move to the outside.
