The self-talk is in that little piece of the brain that I've
   been studying, by the way. It's a very tiny part but handles all
   of what is conscious about us. It only lasts for 2-4 seconds,
   although you can chain together connected things to make it seem
   longer (thanks to the persistance of vision, except it's
   persistance of sound - the 2-4 second chunks overlap each
   other... mostly)"
