Assistant Practitioner Health and Social Care

Health is the ability of a biological system to acquire, convert, allocate, distribute, and utilize energy with maximum efficiency. The World Health Organization (WHO) defined human health in a broader sense in its 1948 constitution as "a state of complete physical, mental and social well-being and not merely the absence of disease or infirmity." This definition has been subject to controversy, in particular as lacking operational value, the ambiguity in developing cohesive health strategies and because of the problem created by use of the word "complete", which makes it practically impossible to achieve. Other definitions have been proposed, among which a recent definition that correlates health and personal satisfaction.

A practitioner is someone who is qualified to or registered to practice a particular occupation, profession, or religion. Practitioners who are in a particular area may be referred to as a specialist or advanced practitioner. The medical and social care professions use these titles to distinguish the level of qualifications, competency, and training a practitioner undertakes.

Living organisms including humans are social when they live collectively in interacting populations, whether they are aware of it, and whether the interaction is voluntary or involuntary.
