INTRODUCTORY The human body a perfect machine--How to keep well--Outdoor sleeping--Exercise and play--Smoking--Walking Suppose you should wake up Christmas morning and find yourself to be the owner of a bicycle. It is a brand-new wheel and everything is in perfect working order. The bearings are well oiled, the nickel is bright and shiny and it is all tuned up and ready for use. If you are a careful, sensible boy you can have fun with it for a long time until finally, like the One Hoss Shay in the poem, it wears out and goes to pieces all at once. On the other hand, if you are careless or indifferent or lazy you may allow the machine to get out of order or to become rusty from disuse, or perhaps when a nut works loose you neglect it and have a breakdown on the road.
