Mate value

Here's an interesting style of how couples are attracted to each other. The premise is that when people first meet, they tend to click with people who are as attractive as they are. But as they get to know each other, perceptions can change. People can become more attractive or less attractive, which leads to the Plain Jane, Hot Stud connection .

I would be interested in your reaction.
