Games Played With a Ball

"As to the species of exercise, I advise the gun. While this gives a moderate exercise to the body, it gives boldness, enterprize, and independance to the mind. Games played with the ball and others of that nature, are too violent for the body and stamp no character on the mind. Let your gun therefore be the constant companion of your walks."
Thomas Jefferson to his nephew Peter Carr, August 19, 1785
