Dear Dr Lee, I dream of the day that every Medical College would have a professor like you. I am speechless how you make it so simple. You are like mother and we student are like spoon feeders. Please keep on making educational videos and benefit those remote students of your's who aren't in direct contact with you as your residents are, but i am certain that they love your teaching if not more then no less than residents at Methodist, Houston
