It used to be that believing that the authorities had implanted a surveillance device in your body would be enough to get you a schizophrenia diagnosis. Today, it's an FDA-approved treatment for schizophrenia.
"When the smart pill enters the stomach, it begins communicating with a patch worn on the patient's arm. The patch records and time-stamps the information from the sensor and collects other information, and then relays it to patients on a mobile phone or other Bluetooth-enabled device." And then on to doctors. And possibly the courts. Or law enforcement.
Come on, don't be paranoid.
