Alex Jack, the editor, has taught and written widely about literature, history, and the healing arts. His books include The Mozart Effect (with Don Campbell), The Cancer-Prevention Diet (with Michio Kushi), and The Adamantine Sherlock Holmes. His earlier medical study of Hamlet showed that blank verse accords with the heartbeat and enhances cardiovascular health. He has been invited by Mark Rylance, artistic director of Shakespeare’s Globe Theater who has performed Hamlet on stage, to present his new book in London later this year.
