My ears of tin are over 50

I am more worried about my metabolism slowing down by 20% at fifty, rather than a slight (hopefully)only hearing loss.Will be awful to look at a snicker bar and put on 5lbs around all my vital organs.
Its far worse if one is a woman, after they have gone past the safe child birth giving age, everything goes south.
Fact of life.

My missus thinks I am deaf because every time she calls me
to do a chore or something I never fail to not hear her.
