Definition of Health

From Population Health.

Definitions of:
 * Health
 * Disease
 * Illness
 * Disability

= Prominent Definitions =

Health

 * WHO (1948) - "Health is a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity"
 * The issue with this definition is clearly the word "complete"---as a result, almost everyone is unhealthy
 * However, the WHO are clearly defining a utopian endpoint, so that we can aim for it. The Preamble to the WHO constitution immediately goes on to refer to "the highest attainable standard of health". Hence it can be a useful theoretical definition, which can inspire useful practical definitions for clinical care & research tasks.
