> And one drink is probably much smaller than people realise: 125 ml wine at 8% ABV is one drink. What is your source for this? The NIH defines a standard drink of wine as 5 oz or about 150ml at 12%. I agree that many people pour more than that since it's less than a cup of wine (about 250ml). I agree with the general sentiment that you should be aware of how much you're drinking, but as the article points out, mortality rate from "alcohol-augmented conditions" is barely a blip until you hit 4-5 drinks daily. It is a U-shaped curve with the most deadly conditions being abstinence and seriously heavy drinking. Given that, I think just being roughly aware of your intake goes a long way. I would love to know how the delta in mortality between 1 daily drink (the optimal) and 5 stacks up against mortality from other common behaviors. I'd hazard a guess that an extra 4 drinks a day is actually less dangerous than obesity or lack of exercise. And yet many people seem a lot more afraid of the effects of having two beers a day than they are of skipping the gym!
