If you have good genes, you can smoke whatever you want, eat anything, drink anything and live to be 100 years old, and go to funeral of all of your peers who have not been as lucky.
If you have not as perfect genes, even if you don't smoke, even if you care what you eat, even if you never drink anything but water and tea ... you may never live to be 100 years old.
Genes are important.
Why do you think we are attracted to beautiful people?
Is the beauty skin deep?
No, beauty usually equals good genes.
We are attracted to beautiful people because if we sleep with them ... our kids have better chances of inheriting good genes.
And, if our kids do inherit good genes, they have got a significant advantage over those who haven't.
Beauty is not skin deep ... beauty is genes deep.
Why are we attracted only to some beautiful people, but not to all of them?
We can see that some people are beautiful, but we are just not attracted to them?
Why? Genes again.
We are attracted only to those who are genetically compatible to us.
If we would always make kids with people who we are most attracted to ... our offspring would be much healthier.
Unfortunately, we try hard to push and suppress our desires ... and we use our brain to choose people. We choose people by their education (they should be as educated as we are), their social status (they should be from the same social class), their background (they should be from a good family), their ethnicity (they should be the same race / same nationality / same culture) ... and so on ...
This often goes against what our heart is telling us ... and we endup with people who are not as perfect match (genetically).
Why did you choose your husband? Was that love ... or some other interest?
I bet it was love. Love and attraction guaranty genetic compatibility.
Genetic compatibility increases chances of healthy offspring.
You are not important. Your husband is not important. Offspring is important. Good offspring means that your blood line will continue and live for the next 1000 years or the next 100 000 years. We can not live to be 1000 years old ... but we can. We live through our children.
