The barbershop pole is a signage that I incorporate into this project.  The bloodletting origins of the barber surgeon is of significant interest to me in reference to the multiple daily blood tests that I must perform. I am interested in the outdated barber surgeon belief that to achieve optimal health one must maintain a correct quantity of blood in the body.  I draw parallels to this bloodletting practice with my own need to test and balance the glucose in my blood through perfectly matched choices of carbohydrates to insulin doses.
