Puzzles aren't just a fun pastime, they can save the world. At least AJ Jacobs thinks so. He's a lifelong lover of crosswords, jigsaws mazes, riddles and sudoku. He says brain teasers exercise the mind, and unite people around a common goal. He sets out to solve one of the greatest riddles of all; why do we love puzzles so much in his new book The Puzzler: One Man's Quest to Solve the Most Baffling Puzzles Ever, from Crosswords to Jigsaws to the Meaning of Life.
