Binge drinking, an activity once confined to college students and the characters on TV’s Mad Men, is a growing trend in the lives of a different group: Baby Boomers. That’s right, government data shows that “23 percent of men between the ages of 50 and 64 admitted to binge drinking in the past month, as did roughly 9 percent of women.” (The definition here for binging is five or more drinks on one occasion in the period of a month, which, you know, really?) Boomers blame their troublesome tippling on the stress of having growing children and elderly parents and mortgages and debt and concerns about the future-a condition some experts refer to as “life”-but there’s another possibility: People like to drink. And they can. So they do. Something to think about.
