=Not an unfortunate period.=--These should not be considered unfortunate periods in life. Proper restraint at this time will bring compensations to those who understand and heed nature’s laws. If men understood that the waning of sexual desire was natural, they certainly would welcome the change and would not use various methods of stimulating and awakening sexual desire. =Minor indications.=--There are several minor signs which when they occur at or near the same time indicate the presence of this change in man. They are as follows: A notable loss of memory, loss of sight, streaks of gray appearing in the hair and beard and an ease of physical and mental fatigue. One or more of these conditions often exist and are due to other causes. =Positive indications.=--The most positive indications of the presence of this change in man are: longer intervals between periods of sexual desire; a less intensity of sexual desire; a greater fatigue following sexual congress; frequency of desire to urinate; slowness to begin urinating; and irritation about the neck of the bladder. If one has been pure in thought, chaste in language and clean in life, this period will be postponed to later years in life and the symptoms will be less marked. =Two advantages.=--There are at least two reasons why men should welcome the waning of sexual desire when the change of life occurs. One is that the period of life, when they are capable of transmitting the best possibilities to their children has passed. The other is that they will need to conserve their sex life, with a view to thirty years more of health, happiness, activity, usefulness, a glorious sunset and a triumphant entrance into the next life. =A larger life.=--A continent single and a temperate married life will make it easy for the middle-aged man to conserve his energy the balance of his days. While his bodily powers may gradually wane, the real man within will rise to a height, grandeur and majesty never before possible. We have all known and read of a few old men who never arrived at their climax of intellectual and moral greatness until they were sixty and seventy. Gladstone was greater at eighty than he was at fifty. =A sad old age.=--The indiscretions of youth and the excess of middle life place many old men where they are physically helpless, great sufferers, make no mental progress and often but little moral progress in old age. =A chance to conserve energy.=--It should not be understood that a decline in sexual desire means the cessation of creative energy, a decline in general health, efficiency or happiness. Nature is giving man a chance to conserve his creative energy, to maintain his health, to increase his efficiency and to perfect his happiness.
