And just one word about fresh air and exercise. Don't bother with either of them. Get your room full of good air, then shut up the windows and keep it. It will keep for years. Anyway, don't keep using your lungs all the time. Let them rest. As for exercise, if you have to take it, take it and put up with it. But as long as you have the price of a hack and can hire other people to play baseball for you and run races and do gymnastics when you sit in the shade and smoke and watch them—great heavens, what more do you want?
