"The recollections of an older man are different from those of a younger man. What seemed vital at forty may lose its significance at seventy. We manufacture stories, after all, from the fleeting sensory material that bombards us at every instant, a fragmented series of pictures, conversations, odors, and the touch of things and people. We delete most of it to live with some semblance of order, and the reshuffling of memory goes on until we die."
