Food scientists say that from two thousand, seven hundred to three thousand, three hundred calories are needed daily, but you will note that this man generally keeps below one-half of this, if you are able to figure food values. People who are trying to get well are often called fools and cranks when they treat themselves properly, but this does not matter, for such fools generally live to see their wise critics prematurely consigned to the earth. When taking health advice, try to keep your balance. Get thoroughly well before you try to guide others. CHAPTER XXX. RETROSPECT. Several hundred pages have been devoted to those matters which must receive attention in order to have good physical and mental health, so as to be able to get the most out of life and give the most, that is, in order to live fully. The basis of health is internal cleanliness, and to attain this it is necessary to exercise self-control and moderation, as well as to cultivate good will and kindliness towards others. Kindness and love lubricate life and make the running smooth. Envy, spite, hatred and the other negative emotions act like sand in the bearings, producing friction in the vital machinery, which they destroy in the end. Success in life means balance, poise, adjustment. We must adjust ourselves so as to be in harmony with others, and we must be in harmony with nature. Our minds will at times be in opposition to the laws of nature. Then we must exercise enough self-control to bring them into harmony again, for natural laws are no respecters of persons. It is said that we break these laws, but that is not true. If we disregard them often enough they break us. We must realize our unity with nature, our at-one-ment. We must realize that we are a part of nature, not above it, and hence that we are governed by the same fixed laws that govern the rest of nature. These laws are for our good. Attempts to escape from their workings indicate a lack of understanding. Discord produces disease and death. Harmony leads to health and long life. The adjustment must be both physical and mental. The physical part means to live or adjust ourselves so that all the functions of the body are carried on normally. The body is self-regulating and if we do nothing harmful health will be our portion. However, life under our present civilization is so complex that the demands upon our nervous systems are excessive. It is easy to live so that we can have health, but to do so is not conventional, and hence not very popular.
