6. Examination by a competent physician whenever any disorder cannot be satisfactorily explained by violation of the daily routine or by interruption of business or domestic routine. Health habits do not become instinctive until a continued, conscious effort is made to accustom the body to them. When this is once done, however, the body not only attends to its primary health needs automatically, but it rebels at their omission, as surely as does the stomach at the omission of dinner. Witness the discomfort of the consumptive, trained to fresh air at a sanatorium, when he returns to his overheated and underventilated home, or the actual pain experienced in readjusting our own healthy bodies to the stuffy workroom or schoolroom after a summer vacation out of doors. I heard a consumptive say that he left a sanatorium for a day class after trying for three nights to sleep in an unventilated ward. For many people the regular morning bath is at first a trial, then a pleasure, and finally a need; if omitted, the body feels thirsty and dissatisfied, the eyes sleepy, and the spirit flags early in the day.

The same diet or the same amount of food or time for eating is not of equal value for all. The temperature of bath water, the kind and quality of food, are influenced by one's work and one's cook. Set rules about these things do more harm than good. Such questions must be decided for each individual,--by his experience or by the advice of a physician,--but they must be decided and the decisions converted into health habits if he would attain the highest efficiency of which he is capable. Here again our old contrast between "doing things" and "getting things done" applies. Get your body to attend to the essential needs for you, and get it to remind you when you let the exigencies of life interfere. Don't burden your mind every day with work that your body will do for you if properly trained.
