My car had a flat battery once. The repair service came by and the guy asked me what I do while he was replacing it. I said I worked in cancer research/healthcare. Without hesitation he said to me: "What do you think about the idea that there is already a cure for cancer, but it is being kept secret because there is more money to be made in treating it?" It occurred to me that it was much, much more likely that superior longlasting battery technology had been invented but was being kept secret because it was more profitable to keep selling batteries. But I didn't say that. There is absolutely zero chance that a 'cure for cancer' is sitting in the locked bottom drawer of a filing cabinet somewhere.
