... and the barman says "Hey, why the long face?"

Here's a video from the aforementioned Festival, in which Alda, Kaufman and neuroscientist Giulio Tononi discuss consciousness, dreams, self, and whatnot. Alda was the moderator, but he does more talking than Charlie. In fact, Charlie barely gets a chance to say anything, which is a bummer -- but the rest of the discussion is good, which is good. And it clocks in at 81 freakin' minutes, which is long. It's from June last year.

Thanks to Sreehari!
