Another example of the medical mindset at work. By far the biggest self-congratulating cretins I've had the misfortune of dealing with have been doctors. They are truly clueless and could be replaced by a mildly-trained parrot with Alzheimer's and I think no one would notice for years.
Dumbasses, EVERYTHING is created by your brain, that's what "real" is you fucking deliberately obtuse frying-pan brained developmentally addled dunces.
Go fill out more forms to order more "tests" so you can ignore the results, you mental invalids.
