Baseball is for every boy a good, wholesome sport. It brings him out of the close confinement of the schoolroom. It takes the stoop from his shoulders and puts hard, honest muscle all over his frame. It rests his eyes, strengthens his lungs, and teaches him self-reliance and courage. Every mother ought to rejoice when her boy says he is on the school or college nine.
~Walter Camp, 1889

“close confinement of the schoolroom” …..a great realization and to me a reminder to get off the computer and go outside.
