Guest: Daniel Pink

Scientists are taking a serious look at timing. What time you take a test, schedule a doctor appointment, appear before a judge in court, or start a new relationship affects the outcome. Science writer DANIEL PINK looks at the research into timing in his new book, When: The Scientific Secrets of Perfect Timing. He comes in to talk to Marty about the ebb and flow in a day, our own biological rhythms and how they both impact success in our lives.
