1.我们真的需要朋友吗?在特定的阶段,那些社会关系脆弱的人死亡率比社会联系紧密的人高50%左右。社会隔绝犹如抽烟酗酒一样糟糕——相当于每天抽15支烟,比不运动和肥胖更糟。幸福感也归因于友情,当然我们需要注重的是友谊的质量而非数量。一项对423个大学生的研究发现,友情的质量对其幸福感影响极大,而朋友数量的多少对其影响不大。 1. Do we really need friends? At a particular stage, those who are socially vulnerable have a mortality rate about 50% higher than people with social connections. Social isolation is as bad as smoking and drinking - the equivalent of smoking 15 cigarettes a day, worse than not exercising and being fat. Happiness is also due to friendship, of course, we need to focus on the quality of friendship rather than quantity. A study of 423 undergraduates found that the quality of friendship has a huge impact on their well-being, while the number of friends has little effect on them.
