Not a drinker. As a person who makes their living using their brain, it's never made sense to me to not protect an important asset. Over the years, most of my peers have stopped being able to do any sort of intensive brain work because of (a) drinking, (b) sugar, or (c) smoking or some other drug. Over the years, the decline in ability due to these things is obvious. I regularly outperform people 20 years younger than me because of poor lifestyle choices they're already making.

Society wise, alcohol is the the direct cause, or a major factor in heart disease, cancer, suicide, gun deaths, car deaths and injuries, etc.
