Study: Drinking Alcohol Every Day Can Shorten Life. The source for this photo, GlobalVoicesOnline.org, says that in Japan, drinking can be a social obligation. Here’s another study that addresses, not just amount of alcohol consumed, but frequency … how many days a week one drinks at all. It’s much bigger than the one I just posted. It analyzed data from 88,746 men and women from Japan and found the same thing, that drinking alcohol every day can shorten life: Patterns Of Alcohol Drinking And All-Cause Mortality: Results From A Large-Scale Population-Based Cohort Study In Japan, American Journal of Epidemiology, May 2007.
