I stopped drinking almost 15 years ago. I'm not good at moderation - abstention is easier.
Anyway, I'm dropping into this topic because I happened across an interesting article today that explores the surprising and oft-cited research showing that moderate drinkers live longer and in better health than teetotalers. Apparently, those touted studies did not exclude former heavy drinkers from the teetotaling groups, and the former heavy drinkers on average are much more likely than the lifelong non-drinkers to smoke, be obese, etc. - healthwise, former heavy drinkers have more in common with current heavy drinkers than they do with other non-drinkers!
There is a lot more here - effects of alcohol on women, youthful alcohol consumption as a mid-life breast cancer cause, alcohol as a potent carcinogen generally, and intentionally misleading advertising and research straight out of the Big Tobacco playbook.Did Drinking Give Me Breast Cancer?
