“Without vitamin C,” Anthony writes, “we cannot produce collagen, an essential component of bones, cartilage, tendons and other connective tissues. Collagen binds our wounds, but that binding is replaced continually throughout our lives. Thus in advanced scurvy”—reached when the body has gone too long without vitamin C—“old wounds long thought healed will magically, painfully reappear.”
In a sense, there is no such thing as healing. From paper cuts to surgical scars, our bodies are catalogues of wounds: imperfectly locked doors quietly waiting, sooner or later, to spring back open.

New milling techniques applied to glass and plexiglass panels could be used to “create windows that are also cryptic projectors, summoning ghostly images from sunlight.”
[Pauly and Bompas] hope that the technique will be used in architectural design, to create windows that mould sunlight and throw images or patterns onto walls or floors,” which, if timed, milled, and manipulated just right, could produce a slowly animated sequence of images being projected by an otherwise empty window during different times of day.
That’s the primary difference between an axiom like “Curiosity Killed The Cat” and an axiom like “You Are Not Your User. ” The former rings true in common experience. It’s test-able, like striking a tuning fork or dangling a bit of yarn in front of a kitten. The latter is just some stuff that somebody said.
Sometimes, axiomatic sayings like “You Are Not Your User” no longer have a who that’s saying them. They cease being an actual instruction, and instead serve as a kind of identity, to identify the person who’s repeating the axiom as One Of Us.
The technical term for when an axiom devolves into an ID card is shibboleth: a custom, principle, or belief distinguishing a particular class or group of people, especially a long-standing one regarded as outmoded or no longer important.
