I just read on Huff post that the producer already has an idea about how the show will end. He is toying with the idea of having the last episode being fast forwarded to the present day, with an 84 year old Don Draper. I dunno. The way these characters drink like fish and smoke like chimneys and sleep around I can't see any of the characters making it much past 50 without keeling over. Don will definitely not make it to 2012 imho, I just don't know whether he'll croak from lung cancer or epmphysema, chirrosis of the liver, or AIDS.
