““Walking through the X-ray machine marked the first time I’d taken a step without oxygen in some months, and it felt pretty amazing to walk unencumbered like that, stepping across the Rubicon, the machine’s silence acknowledging that I was, however briefly, a nonmetallicized creature. I felt a bodily sovereignty that I can’t really describe except to say that when I was a kid I used to have a really heavy backpack that I carried everywhere with all my books in it, and if I walked around with the backpack for long enough, when I took it off I felt like I was floating.””
