The efficient body is clean internally. An unclean skin is bad. A foul alimentary tract is worse. But the worst of all is a foul condition of all the tissues, including the blood-stream, a condition in which much of the body's waste is stored up, instead of being excreted. If such a condition can not be remedied through moderation and simplicity in eating, the only thing that will prove of value is temporary abstinence. It would be an easy matter to enumerate many long fasts, such as that of Dr. Tanner, who proved to an astonished country that fasting for a month or more is not fatal, but on the contrary may be beneficial. Or we could cite cases like the fasts carried on by classes under the direction of Bernarr Macfadden. Or we could refer to the experiments of Professors Fisher and Chittenden of Yale. However, we will only look into one more case, that of Dr. I. J. Eales, whose fast created considerable interest several years ago. The doctor was too heavy, so he decided to take a fast to reduce his weight, also for scientific purposes. For thirty days he lived on nothing but water with an occasional glass of lemonade and one cup of coffee. At the end of thirty days he broke his fast on a glass of malted milk. The doctor worked hard during all this period, losing weight all the time, being thirty pounds lighter at the end of his fast than at the beginning. However, he did not lose strength, being able to do as much work and lift as heavy weights at the end of the fast as at the beginning. Anyone who is much over weight can with benefit do as the doctor did, for the body will use the stored up fat to produce heat and energy. This fast is fully detailed in Dr. Eales' book called Healthology. Fasting is the quickest way to produce internal cleanliness, which is health. When the system is clean the cravings, longings and appetites are not so strong as when the body is full of poisons. For this reason a fast is the best way to destroy the cravings for tobacco, coffee, tea, alcohol and other habit-forming drugs. If, after the fast is over, the individual lives moderately and simply, and is fully determined not to return to the use of these drugs, a permanent cure will be the reward. However, it is very easy to drift back into the old habits. A permanent cure requires that there be no compromise, no saying, "I shall do it this time, but never again." Once the old habit is resumed, it is almost certain to be continued. CHAPTER XXVI. ATTITUDE OF PARENT TOWARD CHILD. Healthy, happy children are the greatest of all rewards. All parents can have such children, and it is a duty they owe themselves, the children and the race. It is a most pleasant duty, for the returns are far greater than the cost.
