What is health indeed? According to Wikipedia, health is the level of functional or metabolic efficiency of a living being. In humans, it is the general condition of a person's 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 lacking operational value and because of the problem created by use of the word "complete", it remains the most enduring.
The maintenance and promotion of health is achieved through different combination of physical, mental, and social well-being, together sometimes referred to as the "health triangle".
Health is metabolic efficiency. Sickness is metabolic inefficiency. Nobody is totally healthy or totally sick. Each of us is a unique combination of health and sickness. And each of us has a unique combination of abilities and disabilities, both emotional and physical.
It is how well we cope with this combination that defines us.
