While many peg 18- to 24-year-olds as the most likely binge drinkers, a new study shows that their parents may be the biggest offenders.

In a new study from BMJ reported by NPR, researchers found that "adults over age 50 who are healthy, active, sociable and well-off are more at risk for harmful drinking than their peers."  The study also found that people with a higher income, people with a higher educational level, female retirees and men with poor dietsare more prone to drink in excess.

The CDC defines binge drinking as 5 or more drinks in two hours for men and four or more drinks in two hours for women.
