I gave a talk about my field of work a couple of months ago, to an audience of people mostly outside it. After the talk, a senior member in the audience came over and asked me a few questions about genetics and health. He had a family history of lung cancer, he said, and he had always assumed it was because everybody in his family smoked a great deal. However, there was a recent article that said that 60% of cancer is due to bad luck, so he was confused about whether smoking had played any role at all.
