In every case that has come under my observation it has been necessary to simplify the food intake, that is, to reduce the quantity and the number of articles of food taken at each meal, also to simplify the cooking. The result is that the individual gets less food, but it is of better quality, for the conventional cooking spoils much of the food. Most of these men neglect to exercise. It is necessary to be active and in the open, also to take good care of that important organ, the skin. Constipation is common, and it is a very annoying symptom, which disappears in time under proper living. The absorption of poisons from a constipated lower bowel is one of the factors that causes premature aging. When the constipation is overcome there are a feeling of physical well-being and a mental clearness which are impossible in the presence of constipation. The treatment of such a condition is very much the same as the treatment of catarrh or any other curable disease, that is, find the errors of living and correct them. It is really surprising how little food people need after they are fifty or sixty years old. If such people eat enough to be well nourished, but not enough to produce any bad feelings there will be no disease. People who die from disease are physical failures, for the natural end does not come in a physical upheaval. Those who live as they should will pass away without any pain. The organism simply grows weary and goes into the last sleep. There are people who say that there needs be no physical death. Harry Gaze wrote an entertaining book on the subject some years ago and gave lectures in this country. It will not convince the average student of nature that people can live forever, for in nature there is constant change. The order of life is birth, development, reproduction, decline and death. It is not likely that man is an exception. It is believed that in olden times men were larger and lived longer than they do today. There is not much foundation for such a belief to rest upon, except in a few cases. The last census shows that there are several thousand centennarians in the United States. In the Technical World for March, 1914, appeared an article by Byron C. Utecht, entitled, "When is Man Old?" This magazine is careful in gathering its facts. I shall quote a few paragraphs:
