Health.

Health is an encompassing term describing the functional efficiency or soundness of an organism. It is usually applied to the physical and mental state, but health is also used in a social context to describe the state of an environment and public health. The World Health Organization (WHO) argues that health is more than the absence of infirmity or disease. There are health checklists such as the International Classification of Functioning (ICF), which measures disability and health, and the worldwide popular International Classification of Diseases (ICD) that defines and measures components of health. Health status is one measure of a nation’s level of achievement, that is, the degree to which its citizens are of sound body, mind, and spirit. Health determinants include lifestyle measures, environmental factors, biomedical aspects, and more recently the role of genetics.
