One reason behind why doctors can’t simply do tests then not follow up is simply medical malpractice suits.
Often times, once you do the test you’re locked into figuring out everything even to the detriment of the patient for fear of getting your license revoked.
Unfortunately not, this was a famous problem taught by Feynman in his physics lectures. Essentially the Brownian motion of the ratchet and pawl mechanism (used in your watch) will eventually prevent the mechanism from harvesting energy [0].
