I guess my question is why do we accept alcohol as a safe choice? There is some unknown number of drinks in some unknown amount of time where alcohol becomes neurotoxic and diminishes memory and general intelligence. The best approximations I have seen is about 4-5 drinks. For those at risk alcohol can push them over the threshold into sleep apnea. Over time alcohol makes one less attractive. Broken blood vessels, and looser skin from the inflammation from going to sleep intoxicated. But clearly alcohol is useful and enjoyed by most adults, its ubiquity at social events is clear evidence, I believe its a critical social imperative to develop and promote healthier alternatives.
