it
Many busy men object to hygiene because, they say, they have no time for
it. They imagine that to devote an hour each day to exercise or
relaxation is a waste of time and that they are really economizing their
time by working that hour instead. We are here referring, not to those
who can not control their working-time, but to those who deliberately
choose to work when hygiene would require them to play. It is often
those who fix their own working-hours, rather than those whose
working-hours are fixed for them, who overwork the most. If these could
know the suffering which sooner or later follows inevitably as the
consequence of this mistaken policy, they would not pursue it for a
single day. A slight loss of working-power comes immediately. A careful
observer of mental workers found that an hour invested in exercise in
the afternoon often pays for itself within a day, by rendering possible
more rapid work. He also found an improvement in the quality of his
work. The razor-edge of the mind needs daily honing through physical
exercise. The same principle applies to all work. It is just as
necessary to stop, at intervals, our physical and mental machinery for
oiling and repairs, as to stop the machinery of a factory.
