As a one time cancer victim (who could end up there again) I was not insulted. It was kinda funny.
I joked about chemo being a great weight loss plan...not that I had any to lose which was to my disadvantage. But my joke made a once heavy lady laugh in the waiting room.
Stick in there, I wish you well. My wife lost her battle after six long years at 43 and I absolutly know she would have thought it was funny too. Barbour, was just stating in clear terms that a run wasn't likely, no more and no less.
