 Another strange note. The first voice you heard as we returned from the break was Dr. Tom Pitts, who is on NBC News. He's a neurologist, specializes in movement disorders, including Parkinson's. And we will play more of that interview next hour during our four. If you do not get our four or have to go somewhere or whatever, grab it later at your convenience via podcast. Armstrong and Getty on demand wherever you like to get podcasts.
