While cheerfulness, hopefulness, good nature, charity and all the mental good qualities are splendid forced-draughts of oxygenised impulse that assist the stomach in consuming and otherwise in taking care of any erratic or excessive food supply, and are able to help take care of a moderate glut of material; Taste, if allowed to serve its full purpose, furnishes its own draught of cheerfulness by means of the very pleasure it distributes, and at the same time it prevents, instead of inducing, gluttony. * * * * * There are two ways of putting a limit to a meal--to eating. One--the wrong one--comes in the shape of a protest on the part of a too full stomach while the appetite is yet ravenous. The right one comes naturally from a perfectly satisfied feeling--a ceasing of desire for anything more, no matter how previously alluring to the palate, before the stomach is overburdened. The former is evidence of glut, or gluttony, and the latter is Nature's way, for which there is every desired reward. SOME EASY EXPERIMENTS It is a very easy matter to prove for one's self that ample saliva is essential to the most economic and perfect digestion; and also, that no two mouthfuls of food require the same quantity. Experiment will be doubly interesting in that it reveals pleasure of taste in eating that has not before been enjoyed. The function of saliva in digestion has commonly been understood to be the lubrication of the food so as to enable it to be swallowed. The truth is that it is the first and most important solvent necessary to digestion, the good offices of which are to separate, make alkaline, neutralise, saponify, and otherwise render the succeeding processes within the delicate organs of the body as easy as their delicacy requires, and thus not to strain and inflame them into festering breeding grounds for the myriads of microbes of diseases which we are compelled to draw in with every breath of air we inhale. Drawn into a perfectly clean and healthy organism, some microbes aid and are a part of life, but taken into a system clogged by dirt and strained by overwork, these same harmless creatures become agents of destruction. Bacilli may be either friends or enemies and we have the choice. * * * * * NATURAL LIFE LIMIT It is said that the natural life of all animals, left to pursue a natural existence by being protected from the enemies of their species, and in reach of sufficient nourishment, is six times the growing period. If this is so no man need die or move his soul to another habitation until he has occupied the present one for from one hundred and ten to one hundred and forty years. If the proper use of the instincts and senses be conserved in children, the growing period may be prolonged to probably twenty-five years with a resultant tenure of life of one hundred and fifty years.
