do you think the older we become the less desirable we will be?

Only to shallow people.
I have this friend, she was commenting on how much better her figure was when she was a dancer. I pointed out how she came out of poverty to own two night clubs, how she runs them with mother-hen kind of love; how she prepares wonderful slow-cooked meals for her staff and patrons.
I told her THAT is true beauty. I may have stolen her heart too.
