Yes. As I said about that CSI effect, the general public expects that an autopsy will reveal everything, but sometimes it can't. Sometimes the problems are so subtle that they escape detection. How do you know what you're looking for when you're not certain what you're going to find?
We recently heard at a conference that there may be a genetic factor. One person is doing some significant research with respect to the brain. I alerted some medical people to this potential back in 2000-01. This has become a very complex issue with a variety of potential causes. If there turns out to be a genetic component, I wonder how that will impact on people's perceptions of what has been taking place.
