 I think that kind of change that I think your question suggests if there was one occurred about four years ago and after the incident of March 31st, 1981. But I have to say that the manner in which this was handled explained to me at all in advance. I knew that they had found a polyp, well they had found polyps which had been taken out and which are absolutely benign and harmless. But I'd also known over many years of taking physical exams on a regular basis that there is a form of polyp that does, if allowed to go in the colon and intestine, become a cancerous. So I was going in to have one of the benign polyps removed and in the course of this they found the presence of this other one. And they didn't now know what's called an adenoma and they didn't know whether cancer cells have developed yet or not in that one but you take it out because they will if you leave it there. And when it was taken out I came back in and told me that yes there had been a few what they call the nodes that showed signs of cancer cells but they'd taken it completely out. It had not penetrated the outer wall so it had not spread to any other part of the body or anything. And as the one expert in that business put it to me he said you had cancer. You no longer have it. And I recognize that this means that from now on they'll have to be very regular with checkups. But I was so well prepared and had such knowledge that they'd given me of this particular thing that no I, as I say, the man said I had cancer and I don't have it anymore and I feel fine. Great, thank you. See with me here you don't get any follow up questions. You can do it this way all the time.
