     Are you feeling blue? An American study suggests that being surrounded by happy friends and

neighbors could have more of an effect on your happiness than money. That is the finding of researchers

from Harvard University and the University of California at San Diego.

     Nicholas Christakis and James Fowler studied the emotional health of more than four thousand seven

hundred people. They used information from the Framingham Heart Study. That study began sixty years

ago in the American community of Framingham, Massachusetts. It was started to learn more about the

risks of heart attack and stroke. For the new study, the researchers examined the emotions of the men

and women in the Framingham Heart Study. The information was gathered from 1983 to 2003.

     The researchers found that friends of happy people had a greater chance of being happy themselves.

That means that happiness spreads, or has a contagious effect, among people. And, the smaller the

physical distance between friends, the larger the effect they had on each other's happiness. For example,

a person was twenty percent more likely to feel happy if his/her friend living within one and a half

kilometers was also happy. Having a happy neighbor who lived next door increased an individual's

chance of being happy by thirtyfour percent.The effects of friends' happiness lasted for up to a year.

     Another finding was that people who worked together or were married did not have as much of an

effect on happiness levels as friends did. The researchers said this was often true among friends of the

same sex. A report on the findings was published this month in the British Medical Journal.America's

National Institute on Aging helped to pay for the study. Some researchers who were not involved with

the study questioned its findings. They said the results could be disputed(争议) unless a separate study

showed similar findings.
