Dads may want to think twice before ending their marriages. Besides the negative effects that divorce can have on children , studies suggest that marriage is broadly protective for dads. Married men are healthier than their single and divorced counterparts — they’re more likely to have their skin examined for melanoma ( because their wives point out their skin flaws ) and more likely to get colonoscopies ( because their wives force them to keep their appointments ). The death rate for men who have never been married is 70 percent higher than men who have been married or who are currently married. Marriage isn’t perfect — studies have linked unhappy marriages to high blood pressure and the sort of dip in the immune system that can cause more cases of the flu, arthritis, and dental caries. But, in general, dads are way healthier in wedlock.
