The Last Continent by Terry Pratchett
– A conversation between Rincewind and Death

‘Is it true that your life passes before your eyes before you die?’

YES.

‘Ghastly thought, really.’  Rincewind shuddered.  ‘Oh, gods, I’ve just had another one.  Suppose I am just about to die and this is my whole life passing in front of my eyes?’

I THINK PERHAPS YOU DO NOT UNDERSTAND.  PEOPLE’S WHOLE LIVES DO PASS IN FRONT OF THEIR EYES BEFORE THEY DIE.  THE PROCESS IS CALLED ‘LIVING’.
