Mental Programming

It may not be believed but we are mentally programmed by the things we go through. They change us they alter or thoughts and make us dislike and like certain things as well as attract us to certain ways and lifestyles. Say for instance people, why are we attracted to particular types of people. Why do we have preferences. What generates ones attraction differently than the next person. How one male may be attracted to women of a lighter skin tone that are heavy set while his identical twin might prefer the exact opposite. hmmm....
