Health

Health
Health is the level of functional and metabolic efficiency of a living organism. In humans it is the ability of individuals or communities to adapt and self-manage when facing physical, mental, psychological and social changes with environment. The definition has evolved over time. In keeping with the biomedical perspective, early definitions of health focused on the theme of the body’s ability to function; it was seen as a state of normal function that could be disrupted from time to time by disease. An example of such a definition of health is: “a state characterized by anatomic, physiologic, and psychological integrity; ability to perform personally valued family, work, and community roles; ability to deal with physical, biologic, psychological, and social stress”. Then, in 1948, in a radical departure from previous definitions, the World Health Organization (WHO) proposed a definition that aimed higher: linking health to well-being, in terms of “physical, mental, and social well-being, and not merely the absence of disease and infirmity”. Although this definition was welcomed by some as being innovative, it was also criticized as being vague, excessively broad, and was not construed as measurable.  – Wikipedia
