=4.= Were I an iron and steel automobile, instead of a flesh and blood automobile, which I really am, could I get a license for myself, as a _chauffeur_, to run myself with safety, based upon my knowledge of my own mechanism and the theory and development of my power? =5.= Were I an owner of valuable live-stock, would I employ a farm-hand or a stable man, even at so low a wage as fifteen dollars a month, who knew as little about the proper feeding of my animals as I know about the proper feeding of myself and my children? =6.= Should I employ such an ignorant attendant for my live-stock, and catch him worrying them during their feeding, and hurrying them away from their fodder to hitch them up for work, would I not have the man arrested for cruelty to animals? And yet this is what is habitually done to children! =7.= Do I appreciate how important it is to learn sufficient of the requirements of economic and healthy nutrition to enable me to escape the depressing and debilitating effects of a faulty nutrition. =8.= How can I religiously “ask a blessing” upon food and then immediately sin by treating it in a manner abhorrent to the natural requirements? =9.= If “cleanliness is next to godliness” is it respectable for me to slight my proper feeding in a manner that I know may induce putridity of excreta through indigestion and that _may_ produce fatal disease? =10.= With All Eternity ahead of me, cannot I afford at least 1∕48[3] of my time for careful feeding of my body in a manner known to favour physical health; mental keenness; firmness of character; enjoyable temperance; sexual vigour without morbidity. In fact, general respectability and efficiency? Having duly reasoned out logical answers to the questions, may they not seem sufficiently important to be remembered and respected as a DIETARY TEN COMMANDMENTS? A The Psychology of Nutrition APPETITE ATTENTION APPRECIATION APPETITE is the most important factor in digestion (vide Pawlow). NORMAL APPETITE is indicated by a desire for _some particular_ simple food accompanied by a “watering of the mouth.” FALSE APPETITE is a general discontent of the body, indefinite of description. It is often expressed by “all gone-ness,” or stomach craving, and calls for _something_, ANYTHING! to smother the discomfort of present or recent indigestion. It is like the thirst which follows a debauch. IGNORE FALSE APPETITE, and WAIT for a RETURN of NORMAL APPETITE. It will come as soon as body repairs have been effected by natural agencies and more material is required. No one was ever injured by intelligently and calmly waiting for an appetite. No one ever starved to death for lack of appetite. Most human ills come from forcing appetite, anticipating appetite, abuse of appetite in some form.
