And then there are the rat studies. > ...An unexpected, highly significant finding was observed: the AA rats, bred for high voluntary ethanol drinking, lived much longer than the ANA rats, bred for ethanol avoidance. The death rate by 24 months in the AA line was less than one-third of that in the ANA line. > Conclusions: Lifelong ethanol consumption increased neither the mortality nor the morbidity of AA and ANA line of rats. Genes selected in the development of the high drinking AA line have additional effects producing rats that are healthier and living longer than the ANA rats possessing genes resulting in alcohol avoidance. https://pubmed.ncbi.nlm.nih.gov/14745306/ https://pubmed.ncbi.nlm.nih.gov/14745306/ So what if people who drank were simply _genetically_ healthier to begin with, and moderate drinking has no effect on health outcomes whatsoever? The study seems to suggest that.
