CONFIDENTIAL CHATS WITH BOYS
[CHAPTER I]
THE BODY AS A MACHINE
Any young man who understands the simple facts concerning his body and the laws of human energy, should be able to be as strong in body and nerves at fifty as he is at twenty-five years of age.
If he is strong in body and nerves at fifty he has the increased brain power of experience and work, and only think of the force he has then to utilize for the next twenty years.
This is a practical idea and not a theory or a statement of exceptional cases.
But if this is so, why have not our parents been able to be boys with us instead of old men at fifty? Because they did not understand; never had the plain points shown them; physicians have not always considered this side of boyhood development, and because physiology as taught in the public schools was not that physiology needed by youths and boys.
