my secret of staying young is simple: devote your attention to the part of you that's young and growing  your brain. keep your mind awake and you will stay young ail over. these are exciting times. take an interest in the world around you, and make a point of learning at least one new thing every day.
    no matter how old you are, it's not too late to make your life more interesting. i know a housewife without knowledge in the past who made herself into an excellent industrial designer. i know an old electrical engineer who has become a highly paid artist.
    get over the idea that you are over too old to go back to school. i know a man who entered medical college at 70. he got his degree with honours and became a famous doctor. an other man went to law school at 71 and now is an active lawyer.
    no matter how old people are, staying young is easy for these who live in the future. you can clo it if you are active enough to try. keep your mind awake and active: that's the only youth elixir.

永葆青春的秘诀
    我保持年轻的秘诀很简单：将你的全部注意力放在你身上最年轻并不断在成长的部位——你的大脑上。让你的头脑保持清醒，你就会浑身年轻有劲。这是让人激动兴奋的时代。对周围的世界感兴趣并尽量做到每天至少学一种新的东西。
    不管你年纪有多大，要使生活变得更加有意思，永不嫌晚。我认识一位家庭妇女过去没什么知识，后来使自己成为一名出色的工业设计师。我还认识一位老电气工程师，他后来成为了一名薪水很高的艺术家。
    打消这种念头：你太老了，不可以再回学校了。我认识一位老人70岁时上了医学院，他以优异的成绩获得学位，并成为一名著名的医生。另一位老人71岁时上了法学院，目前是一名活跃的律师。
    无论多老，保持年轻对那些活在将来的人(向前看的人)更容易一些。如果你积极地去试，你就能成功。让你的头脑保持清醒活跃，这是你永葆青春的惟一灵丹妙药。
