Radius of Man’s Locomotion:
"As man has become knowledgeable, he has translated the principles discovered in Universe into abetting his quickness and mobility. The physical effect of this translation has been demonstrated in important degree only within this past half century. Born with legs and not with roots, man is in principle mobile. Prior to World War I man’s locomotion was primarily accomplished by his legs. He rode in vehicles only about 300 miles per year. Oft-repeated Army surveys show that man has always walked an average of 1300 miles per year, and probably always will.
“In 1919, it was evidenced that the species ‘man’ had changed. Man had become an invention which moved about primarily by mechanical means. In the United States he to and fro-ed, in 1919 about 1600 miles mechanically. He continued walking 1300 miles per year, but instead of sitting in rocking chairs, he was sitting in moving automobiles. Thus he totalled 2900 miles in 1919. At the beginning of World War II, the average man was moving mechanically 6000 miles per annum; however, he continued walking an additional 1300 miles per annum, for a total of 7300 miles per year. The U.S. behavior curve in this respect is a pilot or ‘tendril’ curve of the ‘world curve’ to accomplishment”
