Many scientists disagree about what the differences are between the alcohol addict and social drinker. The difference occurs when someone needs to drink. And this need gets in the way of his health or behavior.
And because of this, coffee drinkers are better able to choose ethically produced coffee that puts more money in the hands of the farmers. But, Dan, do the farmers actually see any of this money?
I thought they weren't, but even a man with his finger on the pulse of university culture can be forgiven for the occasional error, their bigger lager drinkers in the main, and their favorite haunt is the temperance.
Of course, what's going on in the brain of a social drinker versus that of an alcoholic are completely different, but the two may run into this same issue... just at drastically different degrees.
