Honoring a beloved mentor with Alzheimer's
When Clay Morton was a student at the University of Arkansas, he was greatly inspired by his geology professor, Dr. Walt Manger, who became a mentor and a guiding light as Morton pursued a career as a high school science teacher. Now, years later, after Manger was diagnosed with Alzheimer's, Morton is striving to preserve as much of his former professor's brilliance as possible. Steve Hartman reports.
