Whether headaches be due to this or any other cause, they should never be neglected, especially if they are liable to come on while at work. For repeated headaches, even though they may be but slight, have a wearing effect on the brain and other parts of the nervous system. They may be due to most trivial causes in some cases, which is all the more pity why they should be allowed to persist. A man who was at the head of a large firm once consulted a doctor because he found that his work took it out of him more than before. The medical man noticed that the patient was slightly deaf, though the latter did not seem to be aware of the fact. On examination, the ears were found to be blocked with wax, the removal of which restored the man to his usual state of health and vigour. It had been simply the strain of trying to hear what was being said which had produced a constant sense of fatigue. [Sidenote: Midday rest.] There is one custom which in these busy times tends to be dying out. It is that of the midday meal rest, the old-fashioned forty winks. “There is no time for it now,” people say. But there is time for everything, if we choose to make it. The head of one of the largest firms in this country used to insist on this rest, no matter how urgent the matters might be that needed his attention. He kept a couch in his private office, and each day, as soon as he had had his lunch, he locked the door, and for twenty minutes took a comfortable rest and snooze. And woe betide anyone who disturbed him. It was to this custom that he attributed the fact that he had retained his faculties and vigour to an age at which most of his confrères were dead or broken down. Some may prefer to have a walk in the fresh air, and if their occupation is a sedentary one and they have been cooped up in an office all the morning, it will probably suit them better than lying down. [Sidenote: Intervals between meals.] It is not uncommon to find cases in which there is over-fatigue because the intervals between the meals is too long, apart from any circumstances which interfere with them. A man gets his breakfast at eight o’clock and his lunch at half-past one it may be. He objects to eating between meals, so takes nothing for the whole of that time. Now this for most people is too long; the system becomes exhausted, and has to do its work without proper nourishment. This means that it has to draw upon the reserve forces, and while this may be done now and then, it cannot be repeated often without depleting them. Many people would find the greatest benefit from a little light refreshment in the course of the morning. They do not need much: a cup of coffee or soup, or a glass of milk and a biscuit, are quite sufficient to keep them going until the luncheon hour.
