healthy

adj. well, not sick, sound, in good health

In 1948, in its constitution, the World Health Organization (WHO) defined health as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity" . In more recent years, this statement has been modified to include the ability to lead a "socially and economically productive life."

Health is a 1980 film directed by Robert Altman. Generally considered to be one of Altman's more underrated movies, "Health" takes a satirical look behind the scenes at a health-food convention at a Florida luxury hotel, where a powerful political organization is deciding upon its new president. This election, however, is not unscathed by backroom deals and scandal. In the middle of the skullduggery is a no-nonsense hotel events manager (Woodard).
