FUNCTIONAL and mobility limitations increase with advancing aging. Many older people have difficulty in simple activities such as walking or standing from a chair, and cannot tolerate even light physical activity. The etiology of these functional limitations is complex and often ascribed to conditions that escape the traditional definition of disease, which is at the core of clinical medicine. Although our society urgently needs new treatments that can reduce the burden of physical decline among older persons, guidelines on how these treatments should be developed and tested are currently lacking in part because a consensus has not yet been achieved regarding the identifiable target diseases. The demographic imperative and resulting burgeoning in population morbidity can no longer be ignored and requires a substantial adaptation of the system of drug development. In simple words, although functional and mobility limitations are increasingly prevalent in older people, only a handful of clinical
