I question how much "work" someone that fits this really gets accomplished. I can run on limited sleep for weeks at a time and am more energized, but throw me at something mentally challenging like Quantum Physics or Solving some Linear Systems model, and it's like my brain says it needs time to process everything, so I end up sleeping absurd amounts. (I also find I make significant headway the next day after that kind of sleep)
