“Sure, genetics do play a role in alcoholism. You're more likely to be an alcoholic if one or both of your parents are also alcoholics. But that's just one part of the equation; the other part is your behavior. You can't become an alcoholic if you never take a drink. So if you know you're predisposed to addiction because you have a family history, then just don't get started, and you'll never find yourself on that path.”
