HEALTH is one of the most valuable and important possessions a person can have. The World Health Organisation defines health as “a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity”. This definition includes an absence of disability, freedom from symptoms and illness, and a general state of wellness.
Hippocrates (370 BC) alluded to wellness as “all parts of the body that have a function, if used in moderation and exercised in labours to which each is accustomed, become healthy and well developed and age slowly. But if unused and left idle, they become liable to disease, defective in growth and age quickly”.
