Walking exercises the whole person. It exercises the body — it gives the arms and legs a workout. It stimulates the flow of blood; expands the lungs. It is gentle and relaxing. It exercises the mind — it shakes up the brain cells. It fills them with oxygen; drives out the cobwebs. A famous scientist says he does his best thinking on the two miles of sidewalk between his home and office.
Walking exercises the emotions. It gives you a chance to observe and enjoy the world. Open your eyes to beauty. See the homes, the trees, the gardens. See the shining faces of little children. Listen for the church chimes, singing birds and the laughter of happy people.
