微笑，整個世界就會跟著你笑。一項研究顯示，快樂

In a good mood? Your neighbor, her friends and even her
friends' friends should thank you - you're likely
infecting them with your cheer. Happiness spreads through
social networks about as easily as the flu, according to
a new study.

 

The researchers analyzed data compiled from nearly 5,000
interconnected people over a 20-year period. After
establishing a baseline mood for each participant, the
team found that when one person became happier, it
rippled through the network, increasing the likelihood that
others would become happier too.

 

Sadness, thankfully, is not nearly as infectious. An attack
of the blues creates a much smaller ripple than a case of
giddiness, said head researcher James Fowler of the
University of California, San Diego.

　讓我們一起快樂吧！雖然是寒冬，但總有一些值得

我們歡笑、喜悅的事物，你會發現身邊多了些掛著笑

臉的親人與朋友。

滿符合造字的規則的，哈~
