 If I were to run, I think they're going to judge me on my vitality. Can I still run up the steps of Air Force Two? Am I still in good shape? Do I have all my faculties? Am I energetic? I think it's totally legitimate for people to ask those questions. This is for the voters to decide. Take a look. Look at me, see if I have the energy, see if I know what I'm talking about, and make their judgment. I think it's a legitimate thing to be concerned about anyone's age, including mine. I think that's totally legitimate.
