Governments run on alcohol and parties (at least in the UK, as demonstrated by Johnson et al.) Not really my area (or even my hemisphere) but US presidents have had a varied history of leadership success and alcohol use (anyone got a chart?). There's a pretty serious genetic element to this too, which seems to get skipped over. Could be in the future a genetic workup will advise against drinking any alcohol for some, while for others it's just a matter of personal taste (within limits).
