Question

Quizplus · Accepted Answer

As Mac drives through the night and gets progressively more tired, he is likely to experience very brief episodes of sleep called microsleeps. These episodes can last from a fraction of a second to several seconds and can be very dangerous while driving. The brain briefly shuts down, and a person is essentially asleep for a few moments, even with their eyes open.
