6. Laugh a Little
Humor stimulates the parts of our brain that use the "feel good" chemical messenger dopamine. That puts laughter in the category of activities you want to do over and over again, such as eating chocolate or having sex. Laughter is pleasurable, perhaps even "addictive," to the brain.
6、常笑常樂
幽默能激發我們大腦里某些部分攝取具有愉悅功能的化學信息物質多巴胺。在做那些喜愛做的事時,多巴胺使人笑由心生,而且樂于一次又一次地、重復地去做,例如,吃巧克力和做愛。笑是如此地令人愉悅,甚至可能使大腦上癮。
