Moderate alcohol consumption inversely correlated with all-cause mortality

My roommate recently sent me a review article that LW might find interesting:

Conclusions: Low levels of alcohol intake (1-2 drinks per day for women and 2-4 drinks per day for men) are inversely associated with total mortality in both men and women. Our findings, while confirming the hazards of excess drinking, indicate potential windows of alcohol intake that may confer a net beneficial effect of moderate drinking, at least in terms of survival.

Personal observation says that LWers tend not to drink very much or often. Perhaps that should change, to the degree suggested by the article?

Apparently walking drunk is actually eight times more dangerous (per mile traveled) than driving drunk. So we would not expect moderate drinkers to have lower death rates due to walking home after drinking - if anything, this would increase their death rate.

I'm extremely surprised by this. I can't see how walking can be that dangerous, provided you walk on sidewalks (or in pedestrian zones) and are careful when crossing the street. What population does the “eight times” statistic apply to?
