*Without health* , no one can as distinctly understand or as *completely fulfill his obligations to himself, to his fellow beings* , or to his Creator. Therefore the health should be as faithfully guarded as the character. A knowledge of physiology and hygiene should be the basis of all educational effort.... Attend to my words; incline thine ear unto my sayings.... For they are life unto those that find them, and *health to all their flesh* . Proverbs 4:20-22.
