Rustico – have you done research on it? I remember either reading or hearing something on some science show about how some people are more predisposed, like, say, Native Americian Indians or Irish. And I think it had to do w/something that was missing from their liver that wouldn’t allow them to process alcohol like other people would.
But certainly I would also believe that if one started out young abusing alcohol and continued through adulthood that it would be much more difficult for that person to curb their drinking. It is habit forming and addicting and for some, I believe also a physical problem.
I also think that certainly people’s personalities play a role in it. Some people are prone to be addicted to things, whether alcohol, drugs, food, etc. I’ve met people in AA who channeled their addictive behavior towards something like working out, exercise, running, yoga, etc. Something that would be healtier. Also, depending on how you look at it, work-aholics. May or may not be less destructive.
