Discussion: Healthcare definition (Wikipedia) with the additional vital sentence I introduced.

The original quote is from Wikipedia.
"Health care (or healthcare) is the maintenance or improvement of health via the prevention, diagnosis, and treatment of disease, illness, injury, and other physical and mental impairments. Health professionals in allied health fields deliver health care."

Plus, I added a sentence to the original Wikipedia definition.
Health care is the maintenance or improvement of health with minimal use of drugs and invasive Medicine. It is the wise use of the close connection between the Body, Mind, and Spirit via the prevention, diagnosis, and treatment of disease, illness, injury, and other physical and mental impairments in people. Health professionals in allied health fields deliver health care.
