How do you define health? Is it just the absence of disease, or does it go deeper?
There are numerous definitions of health - for some it simply means the absence of disease, for others it also includes a concept of unity and harmony within the mind, body and spirit.
The World Health Organization defines it as "a state of complete physical, mental, and social well-being and not merely the absence of disease or infirmity."
Perhaps it is easier to think of health as being a continuum, with a state of optimum well-being at one end, and illness at the other. It is determined by a number of factors including not just physiological, but also psychological, socio-cultural, spiritual, and developmental influences.
In this modern day and age it is also determined by our ability to deal with and defend against stress, which can be a major toll on many people's well-being.
On a subjective level it is something that is unique to each person - we tend to define it ourselves, and have our own standards and measures of how well we feel.
The medical profession is more objective, however, and uses various methods of analysis to measure this nebulous concept. This includes equipment such as Diagnostics Kits, Dialysers, Endoscopes, and Respirometers.
