12. LOST POWERS.--Many young men after their union showed a marked difference. They lost much of their natural vivacity, energy, and strength of voice. Their powers of application, as business men, students, and ministers, had declined, as also their enterprise, fervor, and kindliness. They had become irritable, dull, pale, and complaining. Many cases of rheumatic fever have been induced through impoverishment, caused by excesses on the part of young married men. 13. MIDDLE AGE.--After middle age the sap of a man's life declines in quantity. A man who intends close application to the ministry, to scientific or literary pursuits, where great demands are made upon the brain, must restrain this passion. The supplies for the brain and nervous system are absorbed, and the seed diverted through sexual excesses in the marriage relationship, by fornication, or by any other form of immorality, the man's power must decline: that to this very cause may be attributed the failure and breakdown of so many men of middle age. 14. INTOXICATING DRINKS.--By all means avoid intoxicating drinks. Immorality and alcoholic stimulants, as we have shown, are intimately related to one another. Wine and strong drink inflame the blood, and heat the passions. Attacking the brain, they warp the judgment, and weaken the power of restraint. Avoid what is called good living; it is madness to allow the pleasures of the table to corrupt and corrode the human body. We are not designed for gourmands, much less for educated pigs. Cold water bathing, water as a beverage, simple and wholesome food, regularity of sleep, plenty of exercise; games such as cricket, football, tennis, boating, or bicycling, are among the best possible preventives against lust and animal passion. 15. BEWARE OF IDLENESS.--Indolent leisure means an unoccupied mind. When young men lounge along the streets, in this condition they become an easy prey to the sisterhood of shame and death. Bear in mind that evil thoughts precede evil actions. The hand of the worst thief will not steal until the thief within operates upon the hand without. The members of the body which are capable of becoming instruments of sin, are not involuntary actors. Lustful desires must proceed from brain and heart, ere the fire that consumes burns in the member. * * * * * {437} A Private Talk to Young Men. [Illustration: Young Lincoln Starting to School.]
