It's Brain Awareness Week at The University of Iowa. Host Ben Kieffer speaks with visiting brain scientist Dr. Donald Stuss of the Rotman Research Institute at Baycrest in Toronto. He'll tell us about brain health as we age and the latest research on brain trauma whether it's on the football field or the battlefield. Then, we'll have a conversation with the new President of Grinnell College, Dr. Raynard Kington. We'll talk about his vision for Grinnell College, one of the top liberal arts schools in the country.
