You're welcome to download the data set from the National Epidemiologic Survey on Alcohol and Related Conditions if you want to check the math. The NIH makes it publicly available.
I don't recommend the alternative of seeing some of your friends or relatives drink themselves to death, even as their own closest friends fail to see what's going on. But you don't always have a choice. Sometimes the anecdotes find you.
Anecdotes aren't data, but they are what human beings are designed to believe. If you have trouble envisioning evident facts that are backed by piles of data, perhaps you need to collect a wider range of anecdotes.
10 standard drinks is two bottles of wine, and 3/5 of a bottle of scotch.
(Both using standard, 750 milliliter bottles.)
