I think that, from a biological①standpoint, human life almost reads like a poem.

It has its own rhythm②and beat, its internal cycles of growth and decay③.It begins with innocent childhood,followed by awkward adolescence④trying awkwardly to adapt itself to mature society, with its young passions and follies,its ideals and ambitions; then it reaches a manhood of intense activities, profiting from experience and learning more about society and human nature; at middle age,there is a slight easing of tension⑤, a mellowing of character like the ripening of fruit or the mellowing of good wine, and the gradual acquiring of a more tolerant,more cynical and at the same time a kindlier view of life; then in the sunset of our life, the endocrine⑥glands decrease their activity, and if we have a true philosophy of old age and have ordered our life pattern according to it, it is for us the age of peace and security and leisure⑦and contentment; finally, life flickers out and one goes into eternal⑧sleep, never to wake up again.

我认为，从生物学的角度看，你的一生恰如诗歌。

人生自有其韵律和节奏，自有内在的生成与衰亡。人生始于无邪的童年，经过少年的青涩，带着激情与无知，理想与雄心，笨拙而努力地走向成熟；后来人到壮年，经历渐广，阅人渐多，涉世渐深，收益也渐大；及至中年，人生的紧张得以舒缓，人的性格日渐成熟，如芳馥之果实，如醇美之佳酿，更具容忍之心，处世虽更悲观，但对人生的态度趋于和善；再后来就是人生迟暮，内分泌系统活动减少，若此时吾辈已经悟得老年真谛，并据此安排残年，那生活将和平，宁静，安详而知足；终于，生命之烛摇曳而终熄灭，人开始永远安眠，不再醒来。
