I think this is a self-selecting sample size of health-conscious people who might come to this board due to having pre-existing conditions that make drinking more risky or who might have certain prior experiences or outlooks that make them eschew drinking. I'm not saying that attitude is bad, just that this board may skew sober.
If you posted in Travel, or Food, it may be very different!
As for me: Just back from a ski week with friends. I probably had 2-2.5 drinks over the course of four hours -- a cocktail while helping to prepare food, maybe another while playing a game in front of the fire.
During normal life, I don't drink much during the week. I sometimes don't drink on a weekend, either; other times, if at a friend's house where we're catching up, we'll easily go through a few bottles of wine among us, or 3-4 drinks.
