Thus some cross the conventional deadline of seventy in a state of exhaustion that nature can never entirely make good. Added to all this is the struggle, never so intense for men as in the sixties, to seem younger, to be and remain necessary, and perhaps to circumvent the looming possibilities of displacement by younger men. Thus it is that men often shorten their lives and, what is far more important, impair the quality of their old age, so that we yet see and know but little of what it could, should, or would be if we could order life according to its true nature and intent. Only greater easement between fifty and seventy can bring ripe, healthful, vigorous senectitude, the services of which to the race constitute, as I have elsewhere tried to show, probably the very greatest need of our civilization to-day. In the seventies we often begin to muse on how our environment will look and what our friends will do when we are gone; and now the suspicion, hitherto nebulous, that there are quarters in which our demise would be welcome may arise to consciousness and perhaps take definite form. There are those who, also perhaps unconsciously, are waiting for our place or positions and so we grow hypersensitive to every manifestation of respect or esteem and not only resist being set aside or being superseded but seek to find new kinds of service that will be recognized as useful. The seventieth is the saddest of all birthdays and if we “linger superfluous on the stage,” we feel that society regards us as, to some extent, a class apart; and so we instinctively make more effort to compensate our clumsiness by spryness and gently resist the kindly offices and tokens of respect to which the young incline or, perhaps more often, are taught to render the old. We are a trifle more prone to lose or mislay things, perhaps almost resent the family’s solicitude for our glasses, slippers, cane, overcoat, diet, and quiet. We have to give ever-increasing time and attention to health and to nursing ourselves and in many exceptional experiences feel that we are seeing persons and may be doing things for the last time. All our plans and efforts and prospects directed toward the future have a new element of uncertainty and tentativeness. We can easily be spoiled by kindness or soured by neglect and our own personality requires so much attention in making the new adjustments that are necessary that we are in new danger of becoming selfish; while our nerves are liable to grow irritable and there is a new trend to depressive states as our activities abate.
