p. 214: "All my life I'd been a believing Christian. ... But that instant in the ER--the instant Annette [his wife] died--I seemed to feel my religious faith die, too.

We're organisms; we're conceived, we're born, we live, we die, and we decay. But as we decay we feed the world of the living: plants and bugs and bacteria."
