CHAPTER IX
ALCOHOLIC DRINKS
Drink needed for Health.—Water in the form of sweat and in other ways is constantly passing off from the body. This water carries with it the waste matter which, if it remained, would poison the body. There is some water in the food we eat, but not enough to supply the wants of the body.
Some persons think that the body needs beer or wine to keep it in good order. These liquids, as well as whisky, brandy, and rum, are called alcoholic drinks. The latest experiments and studies show that the body never needs alcoholic drinks to keep it in the best of health. These drinks sometimes make the body sick, and if much alcohol is taken at one time, the person becomes dizzy, staggers, and may fall down and go to sleep.
The Desire for Drink.—When parts of the body have too little water, there is a longing for drink. This is called thirst. As soon as a cup of water is drunk the desire is satisfied. There is no danger of drinking too much pure water.
Persons who have been accustomed to use alcoholic drink have a thirst which water does not satisfy. It is an unnatural thirst. Even beer or wine will not satisfy such a thirst except for a few minutes. Very often a person's thirst is not satisfied until he has used so much wine or whisky that he becomes dull and unsteady in his walk. He is then said to be drunk.
