> "This required food being swallowed to be pushed up an incline. I began eating part of each breakfast (oatmeal) and sometimes lunch (a sandwich) in the exercise position. I would kneel on a platform (which happened to be 6 ½” high), take a normal mouthful, chew it as needed, and prepare to swallow. I would then lay my forearms and the backs of my hands on the floor, rest my head on my hands, and complete the swallowing process. With a little practice, I was soon able to initiate and complete the swallowing process with my head resting on my hands on the floor. I did not attempt to determine what the optimal height of the platform might be or if, indeed, any was necessary."
