An Ordinary Mystic

I spent four months in one of these contraptions
after breaking my neck and severing my spinal cord. As if that weren't enough I also had indentations drilled in each side of my skull that were used to anchor 10 pounds of traction by means of a device resembling ice tongs. The bed turns like a Ferris wheel with the patient suspended across the middle but not 360 degrees, back and forth 180 degrees. My particular routine was four hours on my back, two hours on my stomach, four hours on my back, two hours on my stomach ad infinitum, ad nauseam.
