Definitions of Health
• WHO: Complete state of physical, mental, and social well being; not merely the absence of disease or infirmity
• (1999) “extent to which an individual or group is able, on the one hand, to realized aspirations and satisfy needs; and, on the other hand , to change or cope with the environment.”
