Define health according to WHO.

Health is a complete state of physical, mental, and social well-being, not simply the absence of disease or infirmity. The enjoyment of the highest attainable standard of health is one of the fundamental rights of every human being, regardless of race, religion, political beliefs, or economic or social circumstances.   

The health of all peoples is critical to achieving peace and security, and it is dependent on the full cooperation of individuals and states. The accomplishments of any state in the promotion and protection of health are valuable to everyone. Unequal development in different countries in the promotion of health and disease control, particularly communicable diseases, is a common risk.

The ability to live harmoniously in a changing total environment is essential to the child's healthy development   

The benefits of medical, psychological, and related knowledge must be extended to all people in order for health to be attained to its full potential.       

Hence, health is a complete state of physical, mental, and social well-being, not simply the absence of disease or infirmity
