>Short-sleepers like Ross never feel lethargic, nor do they ever sleep in. I'd be curious to know what her IQ is, how good her memory is, how good her puzzle solving ability is, how creative she is, and other metrics. I'm always a little surprised when I read interviews with people I admire at how much sleep they need. Seems to me, that people who are thought/analytic/creative heavy just rough up their brains more and that might mean a need for longer sleep schedules to recuperate. >A positive outlook is common among all of the short-sleepers that Fu has studied. Smart people are almost always fairly negative if not outright depressed. There's a lot of study in this area. This is an interesting result. I wonder if being a low sleep person comes at the cost of smarts and creativity. Maybe DEC2 comes along with other things we're not looking at and that package may be unappealing once we get the whole picture.
