Is it time to move back school start times? Science and research makes a pretty good argument that the answer is yes; kids have a harder time focusing in the early hours, and need more sleep.

But several local districts are taking a hard look at later start times. We discuss what's ideal, and how to achieve it. Our guests: Dr. Heidi Connolly ,
