I have a very weird stomach and I have seen too many people whose quality of life went down the drain with chemo. I guess I've not had the opportunity to see a positive response to it, and that I guess you probably need to do to be convinced that it's worth doing. Certainly, if I were 20 years younger, I would not hesitate, but I mean, I think that's the price you pay for trying to survive at that point. Although, my sense is the oncologists never want to give up. In fact, the oncologist push the chemo, and the radiologists push the radiation. That's the specialty, that's what you expect of the pitch I suppose.
