I do not recall having seen a greater communicator than Ronald Reagan. On his birthday during the last year of his presidency, he said "Seventy-five years ago I was born in Tampico, Illinois, in a little flat above the bank building. We didn't have any other contact with the bank than that.." These sentences were delivered with such emotive gestures that the audience broke into rapturous applause. His successor George Bush owed his presidency to Reagan's eloquence. "Thank You Sir" acknowledged the grateful Bush celebrating his election victory.

I will leave the art of speaking to general public for another time and switch over to the medical audience.
