a concept called assortative mating. When selecting a mate, most of us tend to be most comfortable with someone who is somewhat like us in terms of physical attractiveness, intellect, sociability, and other traits. That means that we’re choosing people who possess some genes similar to ours, even though we are not closely related. What this all means is that culture and environment—the healthy lifestyle changes you make—are more important than genes for predicting how long you’ll live.
