"Dissapearances happen in science. Disease can suddenly fade away; tumours go missing; we open someone up to discover the cancer is gone. It's unexplained, it's rare, but it happens. We call it misdiagnosis, say we never saw it in the first place. Any explanation but the truth, that life is full of vanishing acts. If something that we didn't know we had disappears, do we miss it?"
