He knows that there will be days ahead, long, tedious days which have no real beginning or ending, but which run together into night and out of it without changing color, or sound, or meaning. He will lie in his bed feeling the minutes and the hours pass through his body like an endless ribbon of pain because time becomes pain then. Light and darkness become pain; all his senses exist only to receive it, to transmit to his mind again and again, with ceaseless repetition, the simple fact that now he is dying.
