We cannot try to change the fixed and immovable laws of nature without paying the penalty. Nature will keep us in order and control our machine, if we fulfill her laws. The sun is in sympathy with our digestive forces; therefore we should rest from labor during the middle of the day, so that the muscles of the stomach may be able to give all the circular movements, and others that are necessary, to thoroughly mix the food with the stomach juices for rapid digestion. Solid foods of the protein class, can only undergo perfect digestion if eaten in the middle of the day. They require many hours to digest, and in this way they are ready for oxidation and assimilation at night, when the air is cool. The body can rest, and the lungs and heart can work better when the stomach is emptied. While on the other hand, if the heaviest meal is taken at night, it is either too rapidly digested by physical force, or it is left half digested in the stomach over night. It congests the liver and kidneys, produces fermentation, robs lungs, heart and skin of their nerve force, and creates an abnormal appetite the next morning for an excess of energy-giving food, or it produces a languid feeling and loss of appetite. Such a system of living is responsible for the large number of acute and chronic diseases and consumption, while those who seemingly keep in good health under such conditions do surely shorten their life. Perfect health and comfort are worth more than earthly possessions, and those who strive earnestly to possess and retain health will find a way to change their system of living. There is strength in union, and if a sufficient number of sensible people demanded different hours for school-children and for people who work indoors, it would be possible to obtain them. During hot summer days or in the tropics the noon hour is not always the best for the heaviest meal of the day, but neither should it be spent for work. Two meals per day is the best plan on hot days. An individual who is always keyed up to the highest point during the middle of the day, and expends the best of his energy for work, cannot expect anything else but bankruptcy. For people who desire two meals per day, the best time for breakfast is between nine and ten in the morning, and for dinner between three and four in the afternoon.
