Alcohol is not required by the body, and, as a rule, to which there are few exceptions, people are much better and healthier without it; for instance, it has been repeatedly proved that soldiers can bear the hard labor of war very much better when no alcohol is given to them. In large and repeated quantities it causes many diseases, such as gout, diseases of the liver, heart, brain, and nerves. When taken, it should never be between meals, but only with food; it should never be given to children except when ordered by a doctor, and should never be taken by those who have insanity or drunkenness in their families. In the treatment of disease it is a most useful drug, but here again only to be used by a doctor's order.
Tobacco-smoking is a habit which should never be indulged in by any one under twenty-one years of age. Even after that age it is merely a luxury, and not a necessity, and if practiced in excess it may cause pain and irregularity of the heart, sore throat, dyspepsia, and partial blindness.
