I think what we both discovered was that oh, these are very inexact signs and the literature is not very clear, and the physicians are being careful and they don't have the answers to most things. There's some hope, I think, in mere human beings that oh, yes, the doctor really knows. Their readings and the exchange with others who are also reading helped us. So I'm having to learn about things I didn't ever want to learn about or need to learn about, and what I'm learning is that there's no easy answer. The flexibility of the system impressed us, but we couldn't have even interacted with it if we hadn't been reading, and studying, and asking questions. So we became some amateur experts in a field that we had no interest up until the moment when we didn't have any choice.
