I saw the most beautiful "lecture" I've ever seen! It's given by a psychiatrist named Jill Bolte Taylor at TED. She recounts her experiences and thoughts she had during a stroke. My machismo doesn't want me to tell you this, but I was nearly moved to tears. It's an 18:42 clip but you can probably start at 4:00 if you need to save a few minutes.
(Sorry, Google won't let me embed non-YouTube videos.)
