Doctors, hard-charging corporate types, and politicians are all known to get by on very little sleep. People often attribute the success that these people enjoy in their careers to the way they use all their time, wasting as little on sleep as possible.
Research published in the Neurology medical journal, though, suggests the very opposite. Being sleep deprived actually shrinks the brain. Another study by the American Academy of Sleep Medicine suggests that if highly-driven people find success while being sleep deprived, they manage it in spite of the little sleep they get and not because of it.
