Consider this a public service announcement for my readers with kids in the 17-23 age bracket:
More than 70 percent of U.S. college students overestimate the amount of alcohol that their peers drink.
And this kind of misperception has a strong effect on personal alcohol consumption and associated problems, according to a study of more than 76,000 students at 130 colleges and universities.

That could be a nifty arrow to have in your quiver when advising your college-bound son or daughter.
