The next time you and your spouse have a blowout, look on the bright side: Exchanging a few not-so-nice words may be good for you, says a new study from the University of Michigan School of Public Health. Researchers there followed nearly 200 couples for 17 years and found that when both people in a marriage suppressed their anger toward each other (rather than arguing), they had twice the risk of dying early compared to couples who shared their emotions—even if just one partner spoke up—and resolved their conflict. Of course, screaming matches aren’t the key to longevity. But if there’s something on your mind, don’t keep it bottled up inside.
