Well, in general, I'm surprised at how seldom practitioners these days actually lay on hands to check about your physical well-being. They tend to go on the results of chemical tests. The other thing about Dr. Gaposchkin is that I'm sorry he's leaving Mass General Brigham. I understand that's going to happen sometimes in May. That's unfortunate.
