In a 20-year study of 1,824 participants, people who had one to three drinks a day were two times more likely to live longer than those who stuck with water and soda pop.

So moderate drinking isn't bad for you. But now get ready for this newsflash: Even drunks live longer than teetotalers. Yep, during the 20 years of this study, 69 percent of the non-drinkers dropped dead, 60 percent of the heavy drinkers died and only 41 percent of the moderate drinkers went to that moderate bar in the sky.
Why? Experts think there are a few behavioral things at play here. One is that non-drinkers tend to have fewer social ties and less family support than casual drinkers. Surprisingly, people who don't drink also skew toward having lower income and education levels, in addition to fewer friends, all of which are factors in the longevity game.
