I don't know if the USA is representative of the rest of the world in this regard but, with respect to drinking, American adults fall into deciles that surprised me[1]. Roughly 40% consumed almost no alcohol in the week before being surveyed, 40% were low-to-moderate drinkers, 10% averaged about two drinks per day, and 10% holy shit that's a lot of booze.
