原文：

根据我个人七八十年的经验，一个人决不能让自己的脑筋投闲置散，要经常让脑筋活动着。根据外国一些科学家实验结果，“用脑伤神”的旧说法已经不能成立，应改为“用脑长寿”。人的衰老主要是脑细胞的死亡。中老年人的脑细胞虽然天天死亡，但人一生中所启用的脑细胞只占细胞总量的四分之一，而且在活动的情况下，每天还有新的脑细胞产生。只要脑筋的活动不停止，新生细胞比死亡细胞数目还要多。勤于动脑筋，则能经常保持脑中血液的流通状态，而且能通过脑筋协调控制全身的功能。

译文：

According to my experience in the past 80-plus years, one should never allow his brain to stay idle; he must use it all the time. Experiments conducted by foreign scientists indicate that the age-old theory that using the brain too much causes physical damage is not valid. In fact, doing so helps achieve a longer life. Ageing is largely caused by the death of brain cells. The brain cells of middle-aged and elderly people die every day, but the fact is that humans use only a quarter of brain cells throughout life and that new cells are born every day when the brain is actively used. As long as the brain stays active, new cells outnumber dead cells. Stay mentally active can enhance blood circulation in the brain and the coordination of body functions.
