 Even for people out there who care about the president's health and are interested in that issue, focusing on the specific health and not the age is very important. I think we have a bias in our society against older people, and it's very important to remember that there are many people out there who are much older than 78 or 81 who can do a fantastic job at what they do. John Paul Stevens, Harry Blackman were on the Supreme Court at substantially older ages, and they did a phenomenal job.
