Microsleeps are a fleeting, uncontrollable episode of sleep which may last from a fraction of a second up to 10 seconds. These episodes occur most frequently when a sleepy person is trying to remain awake. Up to 20% of crashes in Australia are blamed on this phenomena. Dr. Karl, who narrates this video, is best known as an author and science commentator on Australian radio and television.
