But the upside of painful knowledge is so much greater than the downside of blissful ignorance.

但知道真相的痛苦总比蒙在鼓里的快乐要有益得多。

Somehow I lived in blissful ignorance of that fact until quite recently, when I discovered that chemists had pulled off this minor miracle back in 2005.

一直以来我都幸福地无视这个事实，直到最近我才发现原来化学家们将这个微小的奇迹拉回了2005年。

Whilethe friends are concerned for loved ones and the devastation going on in theworld, in some ways they wish they could go back to blissful ignorance.

当朋友们都在关心所爱的人和世界上正在发生的灾难时，某种程度上他们希望他们能重新回到幸福的无知中。
