“We are left with nothing but death, the irreducible fact of our own mortality. Death after a long illness we can accept with resignation. Even accidental death we can ascribe to fate. But for a man to die of no apparent cause, for a man to die simply because he is a man, brings us so close to the invisible boundary between life and death that we no longer know which side we are on. Life becomes death, and it is as if this death has owned this life all along. Death without warning. Which is to say: life stops. And it can stop at any moment.”
