The sense of well being and the increased capacity for work, that follows a moderate exercise of this function, tends to convince us that it has a beneficial effect upon the entire system if exercised moderately. As to what constitutes moderation or temperance depends upon the individual. What would be moderation to some would be excess to others. It may be taken as a general rule that the after-effects will indicate the amount. If the after-effects are irritability, extreme lassitude or a diminution of the love or respect for the other then there has been excess. If the after-effect is a sense of well-being so that the next day one feels more inclined to take up the duties of life, then it may be considered that moderation has been practiced. A certain amount of energy is consumed in any act and, as in our present age we need a great deal of energy to carry on our everyday business, in the majority of cases fresh vitality cannot be spared for an expenditure under several days or a week. Excess in anything tends to bring on premature old age, for the nervous force is expended faster than it is manufactured. Frequently women seem to be endowed with an excess of energy which manifests itself in various forms. Besides this, the woman does not seem to have control of her nervous energy but wastes it in numerous ways. With many a woman the regularity and moderation attendant on a happy married life seems to have a regulating effect upon her whole nervous system, so that she becomes more calm and has greater control over her energies. Wrong training or lack of training in matters pertaining to the relationship of the sexes and to the management of a home may be given as the cause of the majority of unhappy marriages. There must be something wrong with our system of education when the aim of this education seems to be to prepare the girl for a temporary position in an office or store or for a gay social life; and when there is no preparation for the important work of home-making and the rearing of children. A girl would not be expected to run a complicated and delicate piece of machinery without having adequate instruction concerning the necessary care of it. But the girl is allowed to go blindly into marriage and is expected to manage her home and care for her children with practically no preparation. Nowadays we require experts for every position except that of motherhood, but we apparently do not consider that of enough importance to waste any time preparing for it. A man requires his gardener or office assistant to be trained, but the mother of his children need know nothing regarding the preparation for their coming. Too often her only preparation is that of making numerous clothes. She takes no measures to insure a healthy child.
