My mathematical analysis of dating in the later years....
I do some professional reading as part of my work, and one of the mathematical concepts I came across is "survivor bias," which has to do with the fact that we often hear about experiments and studies that describe successful outcomes, while we never hear about the ones that don't work - the medication that is found to be ineffective, the social intervention that does not help with poverty, or something of that ilk.
I decided that "survivor bias" can be applied to dating. As you get older, the dating pool gets smaller, because all the "normal" or "eligible" ones get partnered up, leaving more and more of the encumbered or just plain weird left behind.
Let's take a pool of 1,000 singles who are 20 years old; let's say, each decade, 20% of them disappear because they get hitched: after ten years, you have 800, ten years later, 640, and by the time you make it to 59, the only people left are the dregs, like myself.
So here I am, a dreg, and I'm complaining because most of the women I meet are dregs themselves. As I go longer and longer, the pool shrinks more and more, and more dreggier.
