The World Health Organization (WHO) defines health as; “a state of complete physical, mental, and social well-being and not merely the absence of disease and infirmity”. By viewing health and illness on a continuum, it is possible to consider a person as having neither complete health nor complete illness. Instead, a person's state of health is ever-changing and has the potential to range from high-level wellness to extremely poor health and imminent death.

In the present time diseases are more predictably cured or at least controlled than at any time in the past.
