Ann Arbor, Michigan (CNN) -- There haven't been many times when I have been at a loss for words when conducting an interview as a medical reporter. This was one of those moments.
The man cleared his throat, after ignoring the question I just asked him. "You want to know what I think?" he said loudly.
"I do," I replied.
"Is that what this is about -- you want to know how I really feel, what makes me tick?" he said even louder.
