In the coverage of the press conference, the media referred to me as a “local pediatrician.” Not a scientist, not an authority, not an academic. Local pediatrician. It was true. That’s what I was. But every time I read those words, I felt smaller and smaller, like a clueless quack, a know-nothing. What had I been doing holding a news conference? I had wandered out of my league—and was now being ridiculed. I couldn’t imagine feeling good again, ever.
