90．长寿的秘密
　　长寿的秘密。要好好生活。有两样东西能提早结束生命：愚蠢和堕落。有的人丧生是因为不懂如何保命。有的人是因为不想求生而死亡。正如美德是人自身的奖赏一样，邪恶也是其自身的惩罚。行为放荡之人，生命将加倍的短暂；而行善之人则得以永生。精神的强健传递给肉体，美好的生命不但充实有意义，而且还将得以延长。


90．The secret of long life
　The secret of long life. Lead a good life. Two things bring life speedily to an end: folly and immorality. Some lose their life because they have not the intelligence to keep it, others because they have not the will. Just as virtue is its own reward, so is vice its own punishment. He who lives a fast life runs through life in a doubly quick. A virtuous life never dies. The firmness of the soul is communicated to the body, and a good life is long not only in intention but also in extension.
