Will I live to be 90? I recently picked a new primary care doctor. After two visits and exhaustive lab tests, he said I was doing "fairly well" for my age. A little concerned about that comment, I couldn't resist asking him,Do you think I'll live to be 90?" He asked, "Do you smoke tobacco, or drink alcohol?" "Oh no," I replied. "I'm not doing drugs, either!" Then he asked, "Do you eat rib-eye steaks and barbecued ribs?" I said, "No, my former doctor said that all red meat is unhealthy!" "Do you spend a lot of time in the sun, like playing golf, sailing, hiking, or bicycling?" "No, I don't," I said. He asked, "Do you gamble, drive fast cars, or have a lot of sex?" "No," I said. He looked at me and said, "Then, why do you even give a crap?"
