PHYSICAL AND MENTAL PREPAREDNESS It is not the object of this chapter to deal with a set course of physical culture, but rather to emphasize the necessity of keeping our physical house in order.

There are plenty of books on physical culture which can be relied upon and also any number of physical instructors who are able to advise and help along a set program.

There are hundreds of places, institutions, clubs, Y.M.C.A.'s, and the like, which provide gymnasiums and every other facility for those who determine to build themselves up through consistent physical exercise.

That is all very well to begin with, but afterward we must have some simple methods of our own which will not make it a hardship or a chore to keep ourselves in trim--_a state of physical preparedness_.

It should become a part of our daily scheme to obey certain, simple rules which tend toward an _automatic effort_ instead of a discipline, and we should persevere in these until they become _fixed habits_.
It is no trouble at all to take exercise unconsciously, and we only arrive at this by turning into an exercise any of our ordinary physical actions during the day as we go along.
