One's mental attitude, however, is the most important of all. There is no possible way of keeping young while convinced that one must inevitably manifest the characteristics of old age. The old age thoughts stamp themselves upon the new body cells, so that they very soon look forty, fifty, sixty, or seventy years old. We should hold tenaciously the conviction that none of the cells of the body can be old because they are constantly being renewed, a large part of them every few months. It is impossible for the processes producing senility to get control of the system, or to make very serious changes in the body, unless the mind first gives its consent. Age is not so much a matter of years as of the limpidity, the suppleness of the protoplasm of the cells of the body, and there is nothing which will age the protoplasm like aging thoughts and serenity enemies, such as worry, anxiety, fear, anger, hatred, revenge, or any discordant emotion. If you keep your protoplasm young by holding youthful ideals, there is no reason why you should not live well into the teens of your second century.
Constantly affirm, "I am young because I am perpetually being renewed; my life comes new every instant from the Infinite Source of life. I am new every morning and fresh every evening, because I live, move, and have my being in Him who is the source of all life." Not only affirm this mentally, but also audibly. Make this picture of perpetual rejuvenation and re-creation so vivid that you will feel the thrill of youthful renewal through your entire system.
Some people try to cure the physical ravages made by wrong living and wrong thinking by patching their bodies from the outside. The "beauty parlors" in our great cities are besieged by women who are desperately trying to maintain their youthful appearance, not realizing that the elixir of youth is in one's own mind, not in bottles or boxes. Is there anything quite so ghastly as to see an old lady (really old because her heart is no longer young), with a painted or enameled face, dressed like a young girl? Such a woman deceives no one but herself. Other people can see the old, dry skin beneath the rouge. They can see the wrinkles which she tries to disguise. She cannot cover up her age with such frivolous pretenses. The painting of cheeks and wearing of girlish frocks do not make a person young. It is largely a question of the age of the mind. If the mind has become hardened, dry, uninteresting, if there is no charm in the personality one is old, no matter what his or her years count.
Idle, selfish women of wealth who live an animal life, who are constantly doing things which hasten the appearance of old age, overeating, over-drinking, over-sleeping, idling life away, having nothing to do but gratify every luxurious whim, are the best customers of beauty doctors, who try to erase the earmarks of old age by "treating" the skin and the hair. Doctoring the effects instead of trying to remove the cause of old age never has been, and never can be, really successful. You cannot repair the ravages of age on the outside. You must remove the cause, which is in the mind, in the heart. When the affections are marbleized, when one ceases to be sympathetic and helpful and interested in life, the ravages of old age will appear in spite of all the beauty doctors in the world.
I know indolent wives of rich men, who cannot understand why they age so rapidly in appearance when living such easy, care-free, worry-free lives. They are puzzled to know why it is when they do not have to work, when they have no cares, when their wants are all supplied without any effort of theirs, they do not retain their youthful appearance many years longer than they do. The fact is those women stagnate, and nothing ages one faster than mental and physical stagnation. Work, useful employment of some sort, is the price of all real growth, of all real human expansion. He, or she, who indulges in continuous idleness pays the price in constant deterioration, physical, mental and moral. A ship lying idle in the wharf will rot and go to destruction much more rapidly than a ship at sea in constant use. Every force in nature seems to combine in corroding, destroying the unused thing, the idle person.
Work, love, kindness, sympathy, helpfulness, unselfish interest—these are the eternal youth essences. These never age, and if you make friends with them they will act like a leaven in your life, enriching your nature, sweetening and ennobling your character, and prolonging your youth even to the century mark.
We are learning that the fabled fountain of youth lies in ourselves; is in our own mentality. Perpetual rejuvenation and renewal are possible through right thinking. We look as old as we think and feel, because thought and feeling maintain or change our appearance in exact accordance with their persistence or their variations. It is impossible to appear youthful and remain young unless we feel young. Youthful thinking should be a life habit.
