well 39, at that rate you will spend apporx 45,000 dollars on beer alone in the next ten years. That is assuming you stick to only a half rack daily.
I remember when I would drink only a 12 pack. Nothing. Then it became a case on the weekends/days off. Then it was augmented by stuff that came in a bottle that would burn if you put a match to it.
And on and on...
If you don't stop now that could be you. It doesn't get better, it gets worse if you continue drinking.
