所有老年人共同的大秘密是,在七八十年里你其实没有改变。你的身体变了,但你一点都没变。
The great secret that all old people share is that you really haven't changed in seventy or eighty years. Your body changes, but you don't change at all.
技术可以彻底改变矿业,但前提是我们有勇气接受它。
It is error only, and not truth, that shrinks from inquiry.
生活中唯一的限制是你给自己设定的。
人与人之间都是相互的。爱别人的人,别人一定也爱他;为别人谋求利益的人,别人也一定为其谋求利益;憎恨别人的人,别人一定也憎恨他;残害别人的人,别人也会残害他。
The resilience of nature gives me hope.
