Being an enrolled member of an Indian tribe and Irish, my ability to be damn good drinker is off the charts. Both my parent's fathers were alcholics. From my experience, Indians are great enablers. That is a significant part of the problem, IMO. It's a lot easier to have bad habits when your friends and neighbors directly or indirectly support your habit. My Indian Grandpa quit drinking in the early '50s but I vaguely remember being told to be quiet as Grandpa was 'sick', which was the euphemism for 'hangover'.
