今天看到路透社报道一项研究结果，记忆力从中年就开始下退。而此前，人们普遍认为记忆力到60岁才开始减退。下面是主要结果：
- The research team led by Archana Singh-Manoux from the Center for Research in Epidemiology and Population Health in France and University College London found a modest decline in mental reasoning in men and women aged 45-49 years.
- The finding from a 10-year study of more than 7,000 British government workers contradicts previous notions that cognitive decline does not begin before 60 years of age, and it could have far-reaching implications for dementia research.
- Over the 10-year period, there was a 3.6 percent decline in mental reasoning in both men and women aged 45-49 at the start of the study, while the decline for men aged 65-70 was 9.6 percent and 7.4 percent for women.
我在《幸福经济学》里提到，年龄与幸福之间关系呈U型曲线。人在中年时幸福感最糟，这就是所谓的中年危机。每个国家的低谷年龄不太一样，但全球平均最低谷是46岁。从此之后，幸福感反而随着年龄而上升了。
记忆力衰退和幸福指数上升同时起步，是纯属巧合还是有内在联系？我还没有看到已发表的专门讨论这两者之间关系的研究论文，但我可以大胆推测，记忆力衰退和幸福指数上升是有一定的内在关系。
俗话说，“大智若愚”。如果一个人斤斤计较，对什么小事情都记得那么清楚，烦心事就会增多。尤其是网上的事情，不要当真，看后不要放在心上，这样才能保持心态平和，幸福感也会上升。
