How You Bend Your Elbow Controls Who You Know

Nobody knows you like your friends do and scientist have recently discovered an actual gene that links both your drinking and how you pick your friends.

[sic] Three researchers from UC San Diego [sic] focused on six genes in a group of 5,000 people.  The first gene that shows a correlation is DRD2, which also influences drinking behavior. Now, there are obviously some non-biological explanations for why that relationship might exist. After all, people who possess the gene are more likely to be social drinkers, which in turn means they're more likely to meet similar people at bars or parties. But the strength of the connection does seem to suggest there's a biological component to this as well, as people with the DRD2 gene consistently flocked together.

The final gene of the six also showed a relationship, although it was a negative one, meaning that we're attracted to people who display the opposite of some of our traits. What's intriguing about these results is they actually seem to have found a genetic basis for relationship clichés like "opposites attract." Indeed, what this study is basically talking about is chemistry, the notion that some people just seem to naturally click together better than others.
