Most people would say there’s no “right” age to get married. You should do it when you find the person you love, and you’re both ready. Well, those people are wrong. There is a right age to get married. And it’s 31.

A new study out of the University of Utah found that people who get married when they’re 31 have the lowest risk of divorce.

Basically, the odds of getting divorced are the highest if you get married in your early 20s. Then they go down about 11 percent every year after that, and bottom out at age 31.

But from age 32 on, your odds of getting divorced go UP about 5% every year. That’s pretty surprising, and the researchers say it’s a new trend that just started over the past two decades.

They’re also not exactly sure why it happens. Their best guess is that people who wait to get married might just not be marriage material, but they do it because they think they’re “supposed to” and then it goes badly.
