It’s true that a woman’s so called “sexual market value” will decrease as she ages. Study after study shows that men find women in their 20's the most attractive.

For starters, every human being has intrinsic worth. Ugly or beautiful. Secondly, older women can have worth in a thousand different ways that don’t involve being attractive to men.
