For any of you who haven't been around a while and think these discussions about drinking are pretty out of hand, think again. We've had far more intense discussions than this.
I wonder how much research went into the .08 figure that seems to be the predominant legal definition here in North America. I assume a lot.
I know some alcoholics who can really knock back the booze and still seem pretty normal. Still, handle it as they may, I wouldn't want a good liquor holding alchy driving me around LA at 0.12. He might seem normal as hell and function better than the average guy and even drive well in that state, but I wouldn't trust his judgement in a squeeze.
.... so what level of impairment is acceptable? Surely, .00 is rubbish. If alcohol is that bad, perhaps it should be prohibited outright.
