Most people live their lives as if the end were always years away. They measure their days in love, laughter, accomplishment, and loss. There are moments of sunshine and storm. There are schedules, phone calls, careers, anxieties, joys, exotic trips, favorite foods, romance, shame, and hunger. A person can be defined by clothing, the smell of his breath, the way she combs her hair, the shape of his torso, or even the company she keeps. All over the world, children love their parents and yearn for love in return. They revel in the touch of parental hands on their faces. And even on the worst of days, each person has dreams about the future—dreams that sometimes come true. Such is life. Yet life can end in less time than it takes to draw one breath.
