Bicycle Face, Subway Eye, and Auto Legs
Some years ago we first heard of the "bicycle face," acquired by persons who persistently "scorched" on their wheels, while leaning low over the handle-bars. The "subway eye" has recently developed in employees of the New York Subway. It is a disease of the retina, caused by the peculiar conditions in the tunnel. But the latest development in physical infirmities is what is termed "auto legs." This is an atrophied condition of the leg muscles due to a constant sitting posture under the strain of fast motion over uneven ground. The vibration under these conditions affects the nerves of the leg muscles, and so causes the shrinking of the flesh.
