     What makes people happier:money or having happy friends and neighbors? Scientists have found

an answer as part of a study.    

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

And the smaller the distance between friends,the larger the effect they had on each other's happiness.      

     For example,a person was 20% more likely to feel happy if a friend who lived within  l. 5 kilometers.

Having a happy neighbor who lived next door increased the chance of being happy by 34%. The effects

of friends' happiness lasted for up to a year.      

    The scientists found that sadness also spread among friends,but not as much as happiness.      

     People who take 3 degrees out of' separation still had an effect on a person's happiness.3 degrees

of separation means the friend of a friend of a friend.      

     The study showed that having an extra 5 ,000 dollars increased a person's chances of becoming

happier by about 2 percent. But the researchers found that the influence of a friend of a friend of a

friend can be greater than that.
