For the same reason a cup of tea with bread and butter or cake about four o’clock or thereabouts is an excellent thing. And like the morning snack, it provides more than nourishment, for it necessitates a break and a breath of fresh air, which invigorate the nervous system, and often enable a man to reach home fresh and well, when otherwise he would get there jaded and tired. [Sidenote: Nature of work.] Sometimes it is the nature of the work which imposes a special strain. Great responsibilities and grave issues may have to be met, as in the case of contractors, stockbrokers, etc. An enormous degree of nervous tension may have to be concentrated into a few minutes. There is no escaping from it, we know. Yet the man who has consistently looked after his health, not only in the mornings before setting out but at all other times, is in a much more satisfactory state to deal with such emergencies and to bear the strain of them. [Sidenote: Working against time.] Often it is working against time which does the harm. Sometimes this rush cannot be helped. The journalist, for instance, must have his news or his leader ready by a certain hour. The newspaper, like time and tide, cannot wait. Yet at other times it _can_ be helped. A man finds that if he goes on for another hour, instead of going to his lunch or dinner at the proper time, he can finish what there is to do. He may finish his work, to be sure. Often he finishes himself at the same time. It would be to his advantage in the long run, if he left the work and had his meal, and returned to complete his duties afterwards. This interference with meal-times is a fruitful source of nervous exhaustion and breakdown. The system is deprived of nourishment just when it is most in need of it. Every meal postponed under such circumstances brings the hour of retribution nearer. [Sidenote: Mental effect of hurry.] Apart from interference with meals, working against time has a bad effect of its own. It is like running for a train. A man who could cover the same distance in the same time without any effort if there was no train to catch will arrive at the station breathless. The anxiety of getting there in time has caused a mental disturbance, which has affected the heart on its own account. In the same way there are cases of nervous exhaustion and loss of health due entirely to the habit of rushing at correspondence in order to get it off by a certain post. It may have to be done, but the man would be better off in the end if he lost the business rather than acquire it at the expense of his health. [Sidenote: Public work.] There is a peculiar strain connected with work which demands appearing before the public. It is pitiable to reflect how many artistes, actors, musicians, and others break down in their efforts to give pleasure and diversion to the tired minds of others.
