Researchers have known for a while that conscientious people live longer. Now researchers at the University of Illinois are looking at how one’s personality can influence the health of another—and they’ve found that having a conscientious partner is also good for you. The study on conscientious spouses or romantic partners also found that women get an added (though small) health benefit when paired with someone who is conscientious—and neurotic. Although, the when it comes to men, having a neurotic partner does not have the same health benefit.
