What makes people happier, money or having
happy friends? Researchers from Harvard University have found the answer to
this question in a study.
The study found that people who have happy
friends have a greater chance of being happy. And if the happy friends are closer
to you, you will be happier. For example, a person's happiness rises by 20% if
a happy friend lives within 1.5 kilometers. Having a happy neighbor makes the
chance of being happy higher by 34%. The effects of friends' happiness last for
up to a year.
The researchers found that happiness is
really contagious. Sadness also spreads among friends, but not as much
as happiness. The study shows that having an extra (额外的) five thousand dollars increases a person's chances of becoming
happier by about 2%. But the effect of a friend's happiness could in fact be
greater than that.
The study also shows that people are
happier when having happy friends than having good colleagues (同事) .
