This is not unexpected, but very sad. Imagine everything that was in this guy's head: All the people, the experiences, the history, the stories, the movies-- a whole universe in there. He left a lot behind for us, but the essence of it all is gone. He was a one-of-a-kind person who led a one-of-a-kind life. There will never be another.
I think it was last year, or maybe the year before, that I heard him interviewed by Chase Masterson on an Internet Radio Program; it was so heartwarming to hear his pleasant reminiscences, yet so sad to hear him sound so old.
