So why were they the ones keeling over?

但为什么这些人反而死得更早呢？

Contemporary illustrations show cathedral spires collapsing, vaults caving in, high scaffolding keeling over in a chaos of planks and poles.

同时代示了大教堂尖塔倾倒，拱顶塌陷，高高脚手架倒在一片糟木板和柱子中。

Only about 15 percent of rocks can preserve fossils, so it's no good keeling over on a future site of granite.

只有大约l5%岩石能够保存化石，因此倒在一个未来花岗岩所在地是没有用处。
