"It is often said that before you die your life passes before your eyes. This is in fact true. It's called living."

This popular quote seems to be a paraphrase of an exchange in The Last Continent: / 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'.
