Cleaning your skin helps to clean your blood. The Japs say that half the good of exercise is lost if you do not have a bath immediately after it.
It may not be always possible for you to get a bath every day, but you can at any rate rub yourself over with a wet towel, or scrub yourself with a dry one, and you ought not to miss a single day in doing this if you want to keep fit and well.
You should also keep clean in your clothing, both your underclothing as well as that which shows. Beat it out with a stick every day before putting it on.
And to be healthy and strong you must keep your blood healthy and clean inside you. This is done by breathing in lots of pure, fresh air, by deep breathing, and by clearing out all dirty matter from inside your stomach, which is done by having a "rear" daily, without fail; many people are the better for having it twice a day. If there is any difficulty about it one day, drink plenty of good water, both morning and evening, and practise body-twisting exercises, and all should be well.
Never start work in the morning without some sort of food inside you, if it is only a cup of hot water.
Never bathe in deep water very soon after a meal, it is very likely to cause cramp, which doubles you up, and so you get drowned.
SMOKING.
A scout does not smoke. Any boy can smoke; it is not such a very wonderful thing to do. But a scout will not do it because he is not such a fool. He knows that when a lad smokes before he is fully grown up it is almost sure to make his heart feeble, and the heart is the most important organ in a lad's body. It pumps the blood all over him to form flesh, bone, and muscle. If the heart does not do its work the body cannot grow to be healthy. Any scout knows that smoking spoils his eyesight, and also his sense of smell, which is of greatest importance to him for scouting on active service.
The boy who apes the man by smoking will never be much good.
