The picture of the Vitruvian Man shows the height of the human body is the exact height of the square, and the arm span of the human body from fingertip to fingertip is the exact width of the square. When arms at full extension and fingertips are at the same height of the body (top of square) the fingertip stays on the perimeter of the circle and at this point the square, fingertip, and circle come into contact. DAVINCI STICK™ length has to be equal to or greater than the body’s height while standing erect and the center of gravity passes from the pit of throat through the umbilicus and pubis between legs, to allow body to extend extremities to maximum within a circle and square.
