What does being “healthy” mean, anyway?

Health can be defined as freedom from physical and mental disease. Freedom from disease is relatively easier to assess and is measured using clearly defined parameters depending on the individual’s system functions.

What is the definition of health and wellbeing?

If healthy means being free from disease, then we have to define what well-being means. The broad common use of the word “well-being” means how well life is going for an individual. Therefore health is only part of well-being albeit an important part. Well-being in its broadest sense includes good health, physical, mental, spiritual, wealth within the individual’s wellbeing context. This allows the individual to set his or her own parameters.

Still in fullest usage, well-being can have a communal aspect to it as well.

The United Nations Development Programme (UNDP) defines well-being as a State of human existence in which a person's basic needs are adequately met and satisfied.
