The necessity for water, and its various uses, have already been discussed. Other beverages are drunk because they are agreeable to the taste or are stimulants or anesthetics. Most uncivilized as well as civilized peoples use beverages that will either stimulate them, and thus relieve a sense of fatigue, or anesthetize them - that is, make them less conscious of it. If the habit of using these beverages be acquired, they are often taken when they are not needed, or in quantities larger than is necessary, and sometimes even to an extent that is harmful.
