Princeton school sets out to find effect of pushing back start time

The Centers for Disease Control says the average start time for the school day is 8:03 in the morning.

One New Jersey school is experimenting with a later start time to improve student health. Correspondent Leah Mishkin reports on how the change is affecting kids.
