Worms.--Where the juices and organs of the body are thoroughly healthy, worms will not appear. Before they can breed, there must be more or less of failure in the patient's health. This shows us that the cure for worms is not so much some poisonous substance which will destroy them, as such an increase of healthy action in the system as will prevent their development. The bowels must be kept open by suitable diet as it is most important to avoid Constipation (_see_). In case of worms in children, stimulus and help are specially needed by the _mucous membrane_ or inner lining of the stomach and bowels. To give this, and at the same time to neutralise and remove waste material from the membrane, a little vinegar and warm water may be frequently given, in teaspoonfuls. This is best taken from an hour to half-an-hour before meals. It is often needful to use some soothing, nourishing substance, such as liquorice, boiled with a little camomile, taken, say after meals, while the acid is taken before them: this has an excellent effect. At the same time, an enema of warm water and vinegar should be given twice a day. Where Santolina (_see_) can be procured, its use will speedily effect a complete cure. Change of air, holiday from lessons, and any other means of increasing the general health, should also be utilised. Worry.--One of the most fruitful causes of ill-health is the habit of worrying. Many believe this to be unavoidable, and think it even an evidence of interest in their work or of consideration for their friends. But this is not real interest or real consideration. The person who faces the work of the moment without anxiety for the future or useless regret for the past will accomplish his task before the harassed careworn man has thought out how to begin it. It is not work that kills but worry. Illness is frequently brought on by worry. Worry wrinkles the face, makes us look old before our time, often makes us sour and disagreeable, always makes us more or less wanting in true politeness, and is socially a great handicap to a man, a much greater to a woman. Further, worry not only prevents cure but kills, and nothing will help us more in recovering from illness than a calm, contented spirit. Now the first thing to do to overcome this habit is to realise that _worry is a bad habit which it is quite possible to get rid of_. The proof of this is that thousands of people for years slaves to it have got rid of it. Through some means or other they have been brought to exercise their will power and have found, sometimes to their considerable astonishment, always to their inexpressible relief, that they have regained a lost mental power and that their efficiency as workers has been enormously increased.
