The benefits of walking are so quickly apparent that I hope to get you to make the start and keep it up for two weeks. Then you will require no further urging.

The Best Exercise.

In walking, there are two most important things to do in order to get the greatest benefits: first—walk alone; second—walk your natural gait. So many people tell me they would like to walk all, or part of the way, between their home and office if they had company.

Company is the very thing you don't want in walking, and there are two reasons for this. One is, if you walk with a friend, you will hold yourself back, or else you will be walking faster than your natural gait. In either case it is a conscious effort, and this conscious effort, to a large degree, will cause you to lose much of the benefit from your walk.

The most important reason, however, is that if you walk with a friend, you are sure to talk, and thus you are using your nervous energy and tiring your brain—the very thing you want to avoid.

Walk, Not Talk.

Walking gives you physical exercise which is absolutely necessary for health. It is the best exercise I know of, because you do not overdo your strength. Walking is beneficial, because when you walk alone, you give your brain a rest. You cannot read the papers, you cannot talk, and your mental apparatus gets complete rest.

I recommend that you walk anywhere from three to four miles in the morning. If your home is more than four miles from the office, walk three or four miles of the distance and then take the car.

Do not walk home in the evening unless the walk is a short one. In the evening you are tired, and you should conserve your strength. In the morning you are fresh, and the exercise comes to you at a time it is most needed. It will give you strength and courage, and help to keep you in a good mood all day.
