Scientists from the Swedish Institute for Social Research have found that a better-educated wife makes for a healthier household. The researchers say that a man living with a woman without a high school education is 25% more likely to die within a decade than a man living with a college graduate. It may be because a more-educated woman knows more about good nutrition. And this study just backs up the other findings of how the choice of husband or wife influences that person's chance of dying early. And another study has already found that living with a husband/wife reduces a person's risk of an earlier death.
