Do you know what the overhead is of the Medicare system? One-point-zero-five percent. Do you know what - private insurance is 30 percent in overhead and profits? Given a choice how I'm going to improve health care I'm going to take it away from private insurance profits and overhead. Wouldn't you?

It has pleased and interested me to see how I could get along under difficult circumstances and with so much discomfort but as I say I was not sent out here to improve my temper or my health or to make me more content with my good things in the East.
