People in couples live longer
At a given age, people who live as a couple have less chance of dying than people who live alone. Once they reach old age, people who have never lived as a couple are an exception to this rule. On the other hand, at all ages, separation or the death of one's spouse is linked to excess mortality, which women seem to withstand best. Marital situations and mortality risks have shared causes. The premature death of people who have never lived as a couple often results from a combination of unfavourable health, social and professional factors which make it more difficult to form a couple. Men and women who have had two children have a lower mortality risk.
