 Look, I think that there are a lot of questions from the American people, and I thought that George Stephanopoulos did a good job of kind of probing and pushing on some of these questions, saying, look, people are concerned about your cognitive abilities. This isn't about you being 81. This is about you showing signs that things aren't well. I thought it was a very fair question to say, would you be willing to take a cognitive test to let us know that everything is okay as you head into advanced age?
