Terminally ill college professor gives his last lecture

I'm almost done watching the lecture, and saw the Diane Sawyer interview.

What an INCREDIBLE human being. Even in the face of this terrible illness he is still one of the wittiest speakers and best presenters I have ever seen. "My son is a doctor but not the type who helps people" probably my favourite line from the entire presentation.
 
I remember I saw him on a show once and his outlook on life is just unbelievable, especially for what he has gone through. He has incredible strength and courage.
