Looks...It's a fact of life. Our bodies change as we age...and not everyone ages gracefully.
Give me a mate with a good mind any day!
Granted, some illnesses steal the mind away. I know the anguish of watching a brilliant mind slowly descend into Alzheimer's. It breaks your heart.
But Momma D's looks fled decades before her mind crumbled. At seventy, her body had begun to give out, but her mind was still sharp. She still was fascinating to talk to.
So while I'd like my mate to have good looks...I don't care if s/he is "hawtt" I cherish the mind far more than I do the shell that carries it.
