jaybird, do I have it correctly that you had a coronary bypass due to blocked artery, or were you on bypass for lungs and blood during open-heart surgery? I'm not clear on that. We're talking about being put on a heart and lung machine while they stop your heart so that they can do their work. When you're all set, sewn up, they paddle you and take you off of the machine, I believe over a minute or three...not sure. So, while they have your heart opened up, and your chest, you are on a 'bypass' machine.
