Based on my recent brush with the medical establishment, I am reminded of the excellent “A Scanner Darkly” by Philip K Dick.

“It’s as if you have two fuel gauges on your car,” the other man said, “and one says your tank is full and the other registers empty. They can’t both be right. [...] Both gauges study exactly the same amount of fuel: the same fuel, the same tank. Actually they test the same thing. You as the driver have only an indirect relationship to the fuel tank, via the gauge or, in your case, gauges. In fact, the tank could fall off entirely and you wouldn’t know until some dashboard indicator told you or finally the engine stopped. [...]“
