This article was written in response to a request from the recent editor of the Proceedings, after he had heard me express myself on the subject of exercise for middle-aged naval officers. In its preparation I am indebted to a number of authors for the ideas I have set forth. I have taken the liberty of quoting some of them almost verbatim because no words of mine could impress as forcibly the truths as they have expressed them. Added to this has been my experience for thirty years as a physician, most of which has been spent in contact with officers of the naval profession. My sole purpose is to help my brother-officers, especially of the middle age, to carry on physically fit as long as possible.
It is entirely pertinent to ask ourselves “What is middle life?” However, it is difficult to be precise in answering. As a general statement let us call it,
that time of life when one realizes the initial appearance of those maladies which influence an individual’s length of life and bear upon the efficiency and well-being of old age.
