LOL! I'm not there yet but, some 50+ women look hot to me. A 40+ Huma is not hot to me. No accounting for taste.
But I'm sure you could describe that quality at 50+, whether it's poise, confidence, glimmer in the eye, or whatever.
I don't see a glimmer in Huma's eye. They look dead to me. That Huma is probably 40-ish represents a youthful intangible (I assume) for the mostly 60+ Freeper men.
