Did someone say coffee?

Boy howdy, do I need love coffee. Drinking coffee feels like it’s in my blood. Perhaps literally. A recent study has identified some pretty interesting genes linked to coffee consumption.

They also found two regions of DNA near genes called BDNF and SLC6A4 that might play a role in how caffeine affects the brain by positive reinforcement. The study participants with a certain variant, who secrete less BDNF, may feel less of the rewarding effects of drinking coffee, according to the study. But the bigger coffee drinkers were more likely to have a certain variant of the SLC6A4 gene, which encodes a protein that transports the brain chemical serotonin.

No, wait. Scratch that. I don’t.
