This claim has all the hallmarks of a made up story (too good to be true, against common wisdom, etc.), but is being spread around social media and appears on TIme, who sources it to a scientific paper.
But even after controlling for nearly all imaginable variables — socioeconomic status, level of physical activity, number of close friends, quality of social support and so on — the researchers (a six-member team led by psychologist Charles Holahan of the University of Texas at Austin) found that over a 20-year period, mortality rates were highest for those who were not current drinkers, regardless of whether they used to be alcoholics, second highest for heavy drinkers and lowest for moderate drinkers.
Is this study reliable? Can we say, scientifically, that heavy drinking on average predicts longer life or is the study being misinterpreted for sentationalism? Or is it simply an unreliable study?
