When will old women stop being jealous of younger?

It's a fact young women in their 20s are more desirable than those in their late 30s or 40s because of biological reasons. Younger women are seen as more desirable because they are more physically pleasing, active, and fertile. From evolutionary perspective they are more desirable hence most men will prefer them over an old woman even if they don't want to have kids.
