I would say though that intelligence and personality are also highly based on the amount they are nurtured, both by the parents and then later as an adult. Intelligence is genetic, but critical thinking and actual knowledge base are much more earned. The parents play a big part of course, in the sense that we are all essentially the product of our environment, but it takes work put in well after the critical parenting period of highest influence (until about age 13) is over. Your parents genes can make you intelligent, but there is nothing more often wasted than a capable mind.
The obvious next difference is that personality and intelligence are the essence of a person throughout their lives, whereas being physically attractive is astonishingly short lived.....Starting that the average women lives about 83 years, a woman does not really reach full physical peak until about age 17, at best. If she is very gifted, she will continue to be highly attractive until about age 32-35, however clearly most do not even make it this long. Many women are only on their top echelon for about 6 years before natural weight gain (a survival mechanism) starts to kick them out of the elite category. The same happens in athletics in men....a really gifted man athletically can only stay at the top for 10 years or so, at most. It isn't that he becomes fat and slow; it's just that the young bucks will start to get more and more an edge, as the margin is tiny. The same happens with women. A woman that is a genetic 7 will be more attractive at age 21 than a genetic 9 is at 31. It is just the way we are designed.
This is all why as a man, you have to learn that your most basic primal extinct in regards to mates, that being genetic value which prefers you take the most attractive, young woman you can to bed is NOT a good strategy for a partner. Or as my father put it once "Looks fade.....stupid is forever."
I know. I am used to people being surprised by my age. I was home-schooled, and I was a freshman in college in the fall that I turned 16.....that isn't actually as uncommon as they tell you though. I remember that I had a few people in my med school class that GRADUATED at 21. We had one guy that couldn't even legally go get a beer, but he was already an MD. I was not all that young there. There is no reason why a person should have to be 18 or 19 before they start college. It cuts down on your earning years, and it is an antiquated setup from when most kids were farmers or factory workers. No sense in waiting that long to get a damn high school diploma!
People my own age are usually incredibly boring to me. I enjoy older people, much more open-minded in the ways that it counts.
