Factor #3: Your Genes
If you’re the type who just can’t keep it together after a few drinks, your genes are at least partly to blame, research suggests. Traits like body sway, poor coordination, and slurred speech are all linked to a specific stretch of your DNA, indicates a study published in the Proceedings of the National Academy of Sciences. U.K. researchers have also identified an “alcoholism gene” that makes some people more likely to pound booze than others. Ironically, people with this gene can typically drink a lot of alcohol without feeling or showing the effects of intoxication, the researchers say.
