Deep breathing habits are imperative and he must be careful not to overtax lungs or heart.
The Laboring Man
The man engaged in muscular work requires plenty of food; he can digest foods which the professional or business man, or the man of sedentary habits, cannot. He will probably be able to drink coffee and tea without any disturbance to nerves or to digestion. In his muscular work he liberates the waste freely and needs fats, starches and sugars to supply the heat and energy. This is especially true of men who work in the fresh air; the muscular action liberates waste and heat and the full breathing freely oxidizes the waste, putting it in condition to be excreted through lungs, skin, kidneys and intestines.
He should have more meat, eggs and nitrogenous foods, and he also needs more carbonaceous foods to supply heat and energy. Three hearty meals a day are necessary.
His muscular movements of the trunk keeps the circulation forceful and the vital organs strong so that his diet may be almost as heavy as that of the football player. Meat or eggs, two or even three times a day, with tea or coffee, and even pie may be eaten with impunity. He needs a good nourishing breakfast of bacon and eggs or meat, also potatoes, or a liberal allowance of bread and butter, corn bread, muffins, etc.
The Aged
The term aged is not governed entirely by years. If one stops physical and mental activity, the vital forces recede, muscles and vital organs become weak and inactive, the waste of the system is not fully relieved and such a man at fifty-five is physically and mentally older than the man who is in active business or is taking daily vigorous exercise, at seventy or eighty. The latter may follow the same diet which he follows at fifty, while the former should follow the diet of the old man who has stopped active work. It should be simple, easily digested and nutritious, and should be reduced in quantity.
