細節改變生活

Bliss

狂喜

Researchers asked volunteers to rate their level of happiness the last time they spent money on themselves or on someone else.

研究者要求志愿者回想一下上次為自己或別人花錢時到底有多開心。

Not only were the givers happier, but when presented with extra cash to use as they wished, they were more apt to spend it on others.

事實上，花錢者不僅更開心了，給他們多余的錢時，他們還會樂于花在別人身上。

The study's authors concluded "a positive feedback loop" exists between offering gifts and well-being。

研究作者總結道，給禮物和人之間有著“積極的回饋循環”。
