Life is a journey. In time, it divides into years, months, weeks, days, and even hours. Throughout the course of a lifetime, there are stages, such as infancy, childhood, adolescence, adulthood, and senior age. Over space, life revolves around home, builds on work, touches upon a profession, expands in a community, traverses within a nation, and reaches out to the world. Along various extensions of a whole life, there are roles played, deeds made, identities acquired, and statuses achieved, from the head of a family to the position holder of a workplace to membership in a professional association to citizenship of a country and, for a few, to certain reputations around the world.
