Heavy alcohol drinkers tend to cluster with each other. This leads to a self-reinforcing cycle wherein they see their peers consuming a lot of alcohol and assume that means it's normal and fine. Likewise, non-drinkers tend to cluster with each other because after a while it's just not fun to hang out with people consuming copious amounts of alcohol all of the time while their health slowly declines. I had to stop inviting several friends to certain activities because they wanted to make everything revolve around consuming alcohol. It gets old. Anecdotes aside, the statistics just don't support 10 drinks/night as being average. That's top 10-20% behavior.
