Just saw a video of a raccoon doing a Rubik's Cube blindfolded in under a minute. That raccoon is a puzzle-solving genius! On a different note, did you know that there is a jellyfish that is biologically immortal? The Turritopsis dohrnii can revert back to its juvenile form after reaching maturity, potentially making it live forever, unlike my attempts at solving a Rubik's Cube blindfolded!
