Then there's how medical science works. We had another site visit, and at one point this mean-spirited site inspector said, "You all have to understand, NCI [National Cancer Institute] funds research to stop cancer, it doesn't provide patient care." And another doctor, Richard Cooper, said, "Maybe that's why the rate of cancer has gone up."
Overly simplified? Yes. But worth remembering.
