Peter, Very well put----I could not agree more with you and perhaps JoAnne 1981 could address this issue. Some of us would love to know that we have 6 mos. left and others would stop living and fall into a depressed state or a combination of both. Dr.'s I believe don't try to play God it is just so difficult to predict and they base their prognosis on many similar cases. If we all adhered to stats most of us wouldn't be posting here. There are so many involved and so many lives affected other than the patient that I think I would appreciate an honest calculation from my drs. If I prove them wrong that's not so awful.
