Why fear Middle Age? It is for the majority the time of success, the period of pleasant accomphshment, the age of fruition. At forty a man is in the Prime of Life, and at fifty he is still well within the age of vitality and splendid endeavour. For women Middle Age brings some ill-health certainly, but that should only be in passing, and for them the years past forty need have no terrors. Girlhood and youth lack many sweet gifts brought by the Fairy of Middle Age: experience brings contentment and added powers of enjoyment. In society, in athletics, in friendship, and in her home the woman of forty-five may still reign as a queen and look forward yet to many years of happy activity. But health and fitness are as essentials to the enjoyment of middle life as of the years of effervescent youth. Nerves and good looks, social charm and athletic success are, indeed, increasingly dependent on physical health as the years go by after forty. It is as a helping hand to keeping well and fit in middle age that this little book is written; it is a message to the "forties" and the "fifties" to keep up and doing and learn how to discount the weight of years.
