The rapid “aging” of our population touches almost every sector of science and society essential to successful human and community functioning, including healthcare, public health, behavioral health, recreation and leisure, finance, government and policy, public planning, engineering, media and communications, among others. Each of these sectors faces considerable challenges in adapting to the rapid growth in the size of the older adult population and the increasing length of human life. This includes addressing the needs and desires of individuals in phases of life that previously did not exist or were only experienced by a minority of the population.
