Dorland's Medical Dictionary:
"Health is a state of OPTIMAL PHYSICAL, MENTAL and SOCIAL well-being and NOT merely the ABSENCE of disease and infirmity."

[Basically put, health is not a matter of how good you "feel", health is a measured by having the highest level of physical health, mental health and social health.  Symptoms aren't the problem, they are just the manifestation of a problem - look to the CAUSE, not the symptom.]

Webster's Dictionary:
"Health is a condition of wholeness in which ALL of the TISSUES, ORGANS AND SYSTEMS of the body are FUNCTIONING at 100% ALL of the time."

[Stated in another way, in order to be truly healthy, you must have all of your body parts and they must ALL be functioning at 100% to manifest health.  Basically put, someone without all of their organs/glands cannot be as healthy as someone with all of their organs/glands.]

State of Health:
"HOW your body is FUNCTIONING at a given point in time."
TRUE HEALTH = 100% FUNCTION

[Someone with nerve interference (vertebral subluxation) cannot be as healthy as someone without nerve interference.  Subluxation produces nerve interference, nerves control EVERY function in the human body, nerve interference disrupts organ/gland function, disrupted organ/gland function disrupts the chemical balance, chemical imbalance disrupts all body processes.  It's as simple as that!]
