Being sociable looks like a good way to add years to your life. Relationships with family, friends, neighbours, even pets, will all help, but the biggest longevity (长寿) seems to come from marriage. The effect was first
noticed in 1858 by William Farr, who wrote that widows (寡妇) and widowers (鳏夫) were at a much higher
risk of dying than the married people. Studies since then suggest that marriage could add as much as seven
years to a man's life and two to a woman's. The effect can be seen in all causes of death, whether illness,
accident or self-harm.
Even if the chances are all against you, marriage can more than compensate (补偿) you. Linda Waite of the
University of Chicago has found that a married older man with heart disease can expect to live nearly four years
longer than an unmarried man with a healthy heart. Similarly, a married man who smokes more than a pack a
day is likely to live as long as a divorced man who doesn't smoke. There's a flip side, however, as partners are
more likely to become ill or die in the couple of years following their husband or wife's death, and caring for
your husband or wife with mental disorder can leave you with some of the same severe problems. Even so, the
chances favour marriage. In a 30-year study of more than 10,000 people, Nicholas Christakis of Harvard
Medical School describes how all kinds of social networks have similar effects.
So how does it work? The effects are complicated, affected by socio-economic factors, health-service
provision, emotional support and other more physiological mechanisms (生理机制). For example, social contact can promote development of the brain and immune (免疫) system, leading to better health and less chance of
depression later in life. People in supportive relationships may handle stress better. Then there are the
psychological benefits of a supportive partner.
A life partner, children and good friends are all recommended if you aim to live to 100. The overall social
network is still being mapped out, but Christakis says:"People are inter-connected, so their health is
inter-connected."
