 It seems as if there are so many unknowns still. And maybe we expect too much out of medicine and science sometimes to think that we're going to, like, just a couple of studies in a couple of years and we'll have all the questions answered. That is not the case here. But I'm thinking back to something that Michelle, the caller from Vancouver, Washington, said, that she had the thyroid cancer at a young age. And when she went to seek a physician's help, they had to ask her all ranges of questions, including, had she gone to Chernobyl before?
