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.

[Sidenote: "Too Much Trouble"]

Another objection is that the practise of hygiene is "too much trouble."
It is undoubtedly true, that no one who has unhygienic habits can
overcome them without a certain amount of "trouble." The people who get
the best results are those who are never deterred by trouble so long as
the trouble is worth while. For those who have not the necessary
enthusiasm or self-control to break their unwholesome habits by sheer
will power, the best advice is to so arrange their lives as to make the
practise of hygiene inevitable. One physician in Chicago deliberately
got rid of his automobile and other means of locomotion in order to
force himself to walk to all his patients, and so secure enough physical
exercise. Another man in New York City, with the same object in view,
selected the location for his dwelling so that there was no rapid
transportation available to take him to his office, making the walking
back and forth a necessity from which he could not escape.

[Sidenote: Simplicity of Hygienic Living]

The only difficulty lies in overcoming the inertia of acquired habits.
After one has changed his habits, it is just as easy to live rightly as
to live wrongly. The rules of hygiene are not re
