We've known that all along.
A SMILE IS CONTAGIOUS!!
It makes me laugh that scientist are doing research on it. It's like they think that something can't be true unless they can prove it scientifically....then it's a fact.
Don't get me wrong I think science and research is a VERY important part of our lives. Why waste your time researching something that the world already knows!!
If you would like to read through the article....
The Washington Post (12/5, A8, Stein) reports, "Happiness is contagious, spreading among friends, neighbors, siblings, and spouses like the flu," according to a study published online in the BMJ.
Nicholas Christakis, M.D., Ph.D., of Harvard University, and James Fowler, Ph.D., of the University of California-San Diego, "analyzed information on the happiness of 4,739 participants and their connections with several thousand others...from 1983 to 2003," the New York Times (12/5, A12, Belluck) adds. They found, for instance, that "a next-door neighbor's joy increased one's chance of being happy by 34 percent, but a neighbor down the block had no effect." Meanwhile, "a friend living half a mile away was good for a 42 percent bounce, but the effect was almost half that for a friend two miles away."
The Los Angeles Times (12/5, Kaplan) reports, "The research is part of a growing trend to measure well-being as a crucial component of public health. Scientists have documented that people who describe themselves as happy are likely to live longer, even if they have a chronic illness."
The researchers based this study on data "from the Framingham Heart Study, which has been running since 1948 in Framingham, Massachusetts," Bloomberg News (12/5, Kresge) notes. The authors "defined happiness as a perfect score on the questions 'I felt hopeful about the future,' 'I was happy,' 'I enjoyed life,' and 'I felt that I was just as good as other people.'" According to Dr. Christakis, "The Framingham data had been used before to assess depression as a risk factor for heart disease, but this was the first time researchers looked at happiness across a broad network."
