The doctor should be an educator, so he merits consideration here. Nearly all families have their medical advisers, and these professional people have it in their power to bring more sunshine into the homes than their fees will pay for. On the other hand, they can, and too often do, give both advice and remedies that are harmful They should sow seeds of truth. If the infant is properly cared for, it is never ill. Inasmuch as there are but few families with sufficient knowledge to keep their babies healthy at all times, there are many calls for the doctor. Parents are generally unduly alarmed about their infants. Nearly always the trouble is primarily in the alimentary tract, due to improper feeding, and the doctor with his wide experience can relieve the parental anxiety, and at the same time tell them where they have made their mistakes and how they have brought suffering upon their little ones. Of course, there should be no dosing with medicine and no injections of foreign matter into the blood stream. Rest, quiet, cleanliness and warmth are what the children need to restore them to health. The right kind of physician when acting as adviser to intelligent parents who wish to do the best by their children will see to it that there is little or no disease. If the parents do not know what to do, the most economical procedure is to consult a physician who has understanding of and confidence in nature. Pay no attention to the women of many words who give advice "because they have had many children and have buried them all." It is not as difficult to raise healthy children as sickly ones. It is so simple that it takes many pages to explain it. CHAPTER XXVIII. DURATION OF LIFE. Old age today brings to mind a picture of decrepitude and decay. This is because there is practically no natural old age. Those who live so that they are unhealthy during the early years of life will not be well if they reach advanced years. Old people can be well in body and sound in mind. In order to attain this desirable end, it is necessary to live properly during the first part of life. It is true that people may dissipate and reform and then live long in comfort, but usually those who spend too lavishly destroy their capital and go into physical or mental bankruptcy. There are many who during their prime say that they do not wish to grow old. Their desire for a short life can easily be satisfied. All that is necessary is to live in the conventional manner and the chance of dying before reaching the age of fifty or sixty is good. A few live to be seventy or more in spite of dissipation, but these are the exceptions. They were endowed with excellent constitutions to begin with, constitutions that were made to last over one hundred years. Where we find one who has lived long in spite of intemperance, thousands have died from it.
