Work is the natural heritage of mankind. “Man goeth forth unto his work and to his labour until the evening.” He does so in order to get the means of livelihood. Yet even those who inherit sufficient to make them independent must work also. They may not have to work in order to live, but they must of a certainty work in order to live healthily. [Sidenote: Necessity for work.] A certain statesman, well endowed with this world’s goods, has been known to say that even when he is out of office and on a holiday, he finds it necessary to his personal comfort to study hard for at least two or three hours each day, otherwise his nerves and his heart begin to trouble him. And while making due allowance for patriotism and sense of duty, there is no doubt that many men who do not need to work for a living take up work of some sort or other, politics, the army, or whatever else takes their fancy, because they feel vastly better for having something definite to do. [Sidenote: Work as mental exercise.] Work affords systematic exercise for the mind, and a mind to be healthy needs exercise as much as the body does. Why is it, then, that if work is indispensable to our bodily welfare from a health point of view we all look forward so eagerly to the time when we can retire and leave it behind us? Yet that seems to be the goal towards which we are most of us striving. And it is an aimless one, unless a man has some pursuit by means of which he can use and enjoy his years of leisure, some absorbing hobby or public work of one sort or other. It is the man who has applied himself so closely to his business or profession as to have deadened his interest in other matters, who finds retirement such a deadly dull affair. [Sidenote: How to work and be healthy.] It is often said that a man does his best work before he is forty. The cry is for young men in every branch of employment, and those who have reached middle age stand a poor chance if they are so unfortunate as to lose their situations. Yet their experience ought to make them more useful and indispensable than at any previous stage in their career. A man of fifty-five complained to me some years ago that he was being put on the shelf on account of his age. “Yet I am better fitted to do my work than I have ever been,” he said. It is quite true that he was better fitted for it from the point of view of experience and judgment. Yet he was a confirmed dyspeptic, and was always taking cold, necessitating frequent absences from his work, which was a responsible one. And it is just on this very account that there is a demand for younger and stronger men to-day. Employers prefer a man who is warranted to turn up when he is wanted, rather than a more experienced one who is liable to be at home indisposed at the very time when his services are most urgently needed. They say quite rightly, “We cannot afford to have a man who is in danger of breaking down.”
