Disease prevention through understanding human physiology and the mind-body connection is a fundamental duty.

Original passage

Too little attention is generally given to the preservation of health. It is far better to prevent disease than to know how to treat it when contracted. It is the duty of every person, for his own sake, and for the sake of humanity, to inform himself in regard to the laws of life and conscientiously to obey them. All need to become acquainted with that most wonderful of all organisms, the human body. They should understand the functions of the various organs and the dependence of one upon another for the healthy action of all. They should study the influence of the mind upon the body, and of the body upon the mind, and the laws by which they are governed.
