"The immune system is the key to fighting cancer."

Knowledge is the key to unlocking the mysteries of the universe.

我从不认为任何事情是理所当然的。

对感受者而言，生活是悲剧；对思考者而言，生活是喜剧。

Ah, make the most of what we yet may spend, Before we too into the Dust descend; Dust into Dust, and under Dust to lie, Sans Wine, sans Song, sans Singer, and—sans End!
