Sure, if "wanting someone half your age who's far more attractive" outweighs your desire to not be alone, you're out of luck. But "I'm vain and want a trophy" is a different problem than aging alone.

If you really wanted it you could spend a couple years getting in tip-top shape and expand your pool to more like late-30s and you might have better luck than you think... But you gotta put in SOME effort.
