This distinction between medicine and quigong is a very interesting one. I like your thinking on that. As someone with a long-term health problem (CFS) I've had to think about this stuff a lot to try and work out a strategy for as much self-repair as possible, both on a hardware and software level, to continue your analogy.
Stories where magic is hard graft work at hacking reality always ring truer in some way, maybe because they have analogies in the real world, whereas it always bores me when magicians get power from some sort of unobtainium type plot device.
