?So why would happiness increase with age? One theory is that, as people get older, they become more thankful for what they have and have better control of their emotions. They also spend less time thinking about bad experiences

Happiness is not the only thing that apparently improves with age. In a study, people in their eighties reported the fewest problems with the quality of their sleep.

那么,，為何年齡越大越幸福呢,？一個(gè)理論是，隨著年齡漸長,，人們會對自己所擁有的東西更加感激,，能更好地控制情緒。他們用于考慮糟糕體驗(yàn)的時(shí)間更少,。

這些發(fā)現(xiàn)發(fā)表在《國家科學(xué)研究院學(xué)報(bào)》,。

與年齡明顯同時(shí)增長的不僅有幸福，在一項(xiàng)研究中,，80多歲的人顯示的睡眠質(zhì)量問題最少,。
