Outline of Health (Paperback)

Please note that the content of this book primarily consists of articles available from Wikipedia or other free sources online. Health is the level of functional and (or) metabolic efficiency of a living being. In humans, it is the general condition of a person in mind, body and spirit, usually meaning to be free from illness, injury or pain (as in "good health" or "healthy"). The World Health Organization (WHO) defined health in its broader sense in 1946 as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity." Although this definition has been subject to controversy, in particular as having a lack of operational value and the problem created by use of the word "complete," it remains the most enduring.
