The girl should learn as soon as possible that her health as well as her appearance will depend on her taking daily exercise. She may suppose that exercise is a dull tiresome thing which she is told by other people to take, but which in itself has no interest for her. Here, as in other things, the girl must learn to be her own captain, her own commanding officer. She should give herself orders to take daily exercise. If any of us needs a lesson in keeping well and beautiful, we can get that lesson from our little friends the birds. Every creature, wild and tame, winged and four-footed, takes the most scrupulous care of its physical condition. They clean, stretch, brush, polish, until every feather or hair, until every muscle and sinew is in fit condition. We should think of our bodies as fine instruments which are given into our keeping. The human body is the finest and most wonderful instrument in the world, and it is sad and amazing how often we fail to take the most ordinary care of it. There are different systems of exercise, and the girl should find one that will bring all her muscles properly into play. Five or ten minutes' exercise a day is all that is required. There are many muscles which are not used in walking or ordinary play, and if these muscles are not exercised regularly then that fine instrument your body will get out of good condition and will not show correct and beautiful lines. A girl should train herself to stand properly. A simple test by which she can tell if she is holding herself rightly is to walk a few steps on tiptoe. In order to do this she must hold herself correctly. To have a good body, well shaped and in right proportion, it is necessary to hold one's self correctly all the time. Habits such as these are not acquired all at once. It is only by persistence day by day that the girl will learn to walk and to stand properly and will find that her body is becoming lithe, strong and healthy, an instrument which it is a joy to use and which will make her appearance as attractive as it ought to be. When anything goes wrong which we do not understand, it is generally necessary to consult a physician. Special care should be taken to see a good doctor or dentist, if anything is wrong with eyes or teeth. Other aids to health and happiness are sunshine and fresh air, drinking plenty of good water, useful work, good temper, and good times. To be healthy and happy we must also give affection and kind help to other people. Like everyone else, the girl at work needs holidays. Two weeks in the year is a usual allowance; but three weeks are better than two. After the girl has become a responsible and important worker, she will find two holidays in the year a good investment for health, a short holiday and a longer one of three or four weeks.
