“Last night, there was this actress on TV talking about having colon cancer and saying that everybody over 50 should get tested. It brought back memories of my father’s cancer, how thin and weak he got before he went to the doctor, so that by the time they found the cancer it had already spread too far. But I don’t think I’m at risk. I only eat red meat two or three times a week, and I eat a piece of fruit or a vegetable at every meal. I don’t smoke, and I get plenty of exercise, sunshine, and fresh air working in the vineyard.”
