The operational sex ratio

Found this Wiki article:

Operational sex ratio - Wikipedia

en.wikipedia.org

In the evolutionary biology of sexual reproduction, operational sex ratio (OSR) is the ratio of sexually competing males that are ready to mate to sexually competing females that are ready to mate,[1][2][3] or alternatively the local ratio of fertilizable females to sexually active males at any given time.[4] This differs from physical sex ratio which simply includes all individuals, including those that are sexually inactive or do not compete for mates.

It's OVER for LowOperationalSexRatioCels.

Interesting.
I was in the checkout line at target yesterday and looking around at women.

i started to think about as the population of women age what percentage of them as a whole were still attractive enough over time.

without separating it out over who is single or married but the population as a whole and using landmarks

lets say at age 20. If X women are attractive
By age 30 maybe 0.8 X women are attractive
By age 40 0.5 X women are attractive
By age 50 0.3 X women are attractive

just wondering how quick if falls off
