Aging burdens up all. But particularly women.
We lower in reproductive value. Aging in women is seen as worse than in men. It is expected that a man will be with a younger woman. Women are judged more on looks, which diminish over time, etc.
How do you cope with this?
I'm in a relationship with a man the same age as me, and I find it a tough pill to swallow - that my value is diminished simply by being an aging woman, yet his is largely untouched. I think the power balance will shift as my "mate value" diminishes.
