Well, I think the whole thing about genes is bullshit. I think it's to do about education and circumstance in life.

If you never take a drink, you cannot become addicted. Doesn't matter squat about your genes anymore than your jeans. I think that's bogus fluff set about by the booze companies to exonerate themselves from instigation of addictions through various marketing techniques. It's like saying that people get fat because it's in their genes... it's because they keep pouring fat in their jeans... for whatever reasons of which there are many. Same thing with smokes and booze and "drugs".

The first drinks are cheap at Happy Hour. But, they get expensive as soon as Happy Hour is over.
