most people lose their good looks by 23

the best looking people you will see are young adults in highschool or college age; you generally won't see anyone worth taking a second look at past the age of 23.

why is that?

Sadly I think its evolutions way to get good looking people hooking up and married with kids young, and then to slowly but surely take them off the market, so that they'll stay home with their spouse and raise their kids.

Human Growth Hormone starts depleting, people's faces become puffier and collagen levels drop, men start losing their hair, and women get fat.

And people recede into the crowd, and are on the treadmill of work, provide for family, go home and watch tv, get up and repeated over and over again until they die.
