Fresh air is as important as good water. The lungs of the human body are all the time drawing in air and breathing out air. What we breathe out carries away with it something from our bodies. Therefore it is unhealthy to be in a room with many people, without doors or windows open; for the people draw in all the fresh air, and what they breathe out is more or less corrupted by having passed through their bodies. It is very important to health to have plenty of pure fresh air to breathe. No dirty things, or decaying substances, such as cabbage leaves or mouldy vegetables, or pools of stagnant water, should be allowed to remain anywhere near a dwelling. The pools should be filled up, and the decaying things should be carried away from the house, heaped up and covered with earth to make manure for the garden. If there is not room enough to do that, they should be buried in the ground. Whole families often have fevers from breathing the bad odors that rise from such things. It is morally wrong to indulge in any habits that injure the health or well-being of others. The bed, and the coverings of the bed, should have fresh air let in upon them every day; otherwise, they retain the fluids which are passing from the body all the time. In England, children that worked in large manufactories became pale and sickly and died off fast. When doctors inquired into it, they found that the poor little creatures crept into the same bedclothes week after week, and month after month, without having them washed or aired. Occasional change in articles of food is healthy, as well as agreeable; but it is injurious to eat a great variety of things at the same meal. There are two good rules, so very simple that everybody, rich or poor, can observe them: First, never indulge yourself in eating what you have found by experience does not agree with you; secondly, when you have eaten enough, do not continue to eat merely because the food tastes good. It is foolish to derange the stomach for a long time to please the palate for a short time. If you have oppressed feelings in the head, or sour and bitter tastes in the mouth, or a tendency to sickishness, take nothing but bread and water for two or three days, and you will be very likely to save yourself from a fever. People might spare themselves many a toothache if they would rinse their mouths after every meal, and every night, before going to bed, remove every particle of food from between the teeth, and rinse them thoroughly with water. New toothpicks should be made often, for the sake of cleanliness. Dirt was a necessity of Slavery; and that is one reason, among many others, why freemen should hate it, and try to put it away from their minds, their persons, and their habitations.
