And so it goes.

It is for this reason that all the exercises are so carefully described and the method and manner of walking, marching, or "hiking" receive so much attention.
WORK AND HYGIENE In a book recently published by one of the highest authorities on hygiene in the country, the following statements are made, statements which would prove of especial interest to those of us who have had the pleasure of being members of that "exclusive official Washington club," or of the Senior Service: The problem of the mental worker is to get sufficient physical exercise to keep the mind and body at its maximum efficiency.

This problem gets more and more acute as he gets older.

The amount of work necessary to keep the man of sedentary habits in good condition is about 100 to 150 foot-tons.

Five hundred foot-tons is the amount of work a soldier would perform by marching twenty miles at three miles an hour on a level road.
It is a fallacy to think that sufficient exercise can be taken once a week.
