Health is a state of complete physical, mental and social well-being, and not merely the absence of disease or infirmity.

– World Health Organization, 1948

The more severe the pain or illness, the more severe will be the necessary changes. These may involve breaking bad habits, or acquiring some new and better ones.

– Peter McWilliams, Life 101

The patient should be made to understand that he or she must take charge of his own life. Don’t take your body to the doctor as if he were a repair shop.
