快乐可以传染。这是哈佛大学和加州大学圣地亚哥分校的研究人员一项开创性研究的结果。该研究表明:“情绪是一种集体性的存在——而不仅仅是个体现象。你的快乐不仅仅取决于你的选择和行动,同时也取决于那些你甚至不认识的人的选择和行动。” Happiness can spread. This is the result of a groundbreaking study by researchers at Harvard University and the University of California, San Diego. The study shows that “emotions are a collective existence - not just individual phenomena. Your happiness depends not only on your choices and actions, but also on the choices of people you do not even know action.”
