Our happy hour fact to amaze your drinking buddies with.

Having kids curbs marital satisfaction.

Researchers at the University of Denver tracked 218 couples over eight years and found that 90 percent reported a decrease in the quality of their marriage once their first child was born. This supports a previous, much larger, study which revealed parents are more depressed than non-parents.

According to Scott Stanley, a psychology professor who worked on the Denver study, most couples experience diminished marital quality over time, but having a baby accelerates the deterioration.

Of course, this is an especially fitting Happy Hour Hero fact, since you're probably drinking because your own field research supports it.
