haven't had the windows of your bedroom well open so as to get plenty
of air during the night, you may feel that you are not very hungry for
breakfast. Or perhaps, if you have risen late, or are in a great hurry

How does eating keep you alive and make you grow? Eating is somewhat
like mending a fire. You put wood or coal on the fire, and it keeps
burning and giving out heat; but if you do not put fresh fuel on, the
fire soon goes out. Just so, putting food into your body feeds the
