Sleep \sliːp\(n) ~ the natural state of rest during which your eyes are closed and you become unconscious
O sleep, O gentle sleep, Nature's soft nurse, how have I frighted thee, That thou no more wilt weigh my eyelids down And steep my sense in forgetfulness?
~William Shakespeare, Henry IV, Part I
Cognition \käg-ˈni-shən\(n) ~ conscious mental activities : the activities of thinking, understanding, learning, and remembering
Cognitive psychology tells us that the unaided human mind is vulnerable to many fallacies and illusions because of its reliance on its memory for vivid anecdotes rather than systematic statistics.
Steven Pinker
