and do not foresee from any present symptoms how we shall be left behind in the natural course of things, decline into old age, and drop into the grave

No young man believes he shall ever die. There is a feeling of Eternity in youth, which makes us amends for every thing. To be young is to be one of the Immortal Gods. One half of time indeed is flown – the other half remains in store for us with all its countless treasures; for there is no line drawn, and we see no limit to our hopes and wishes. We make the coming age ourown. “The vast, the unbounded prospect lies before us.” We look round in a new world, full of life, and motion, and ceaseless progress; and feel in ourselves all the vigor and spirit to keep pace with it, and do not foresee from any present symptoms how we shall be left behindin the natural course of things, decline into old age, and drop into the grave

你把这玩意儿丢到谷歌翻译里不就行了么。。。。

而不是从近况来推测我们将会怎么样XXXX，逐渐老去，乃至坠入坟墓.....
那个left behindin the natural course of things，我也不是很清楚，估计要异义

并没有任何原因（使得我们）我们应当不做自然而然的事情，（而）慢慢变老，（最后）进入坟墓

而且，眼前也无任何迹象可以证明，在大自然的发展过程中，我们自己也会落伍，衰老，进入坟墓。
他说的是不要拒绝变老 而不是上面的肤浅意思
