I don't think the degree to which Erdős optimized his life for math is underrated at all. I'd say it's a key feature of what made him who he was, and you'll hear about it in anything involving him that goes past just the work he's done. > I'd imagine that between the drug usage and the hosting, these collaborators didn't get that much sleep. Furthermore, because of Erdős' lifestyle, I'd bet that these papers were primarily written up and refined by his co-authors (Ron Graham in many cases). I doubt he'd have the time, what with the constant traveling. A few of those collaborators were my professors in grad school. You're right: not much sleep was had while Erdős was in town, and the business of publication was primarily handled by the collaborators.
