It's going to have to contact a 3rd party to download the latest health diagnostics/flu of the week/software updates. And speaking of "public good" it would be extremely beneficial to scientists and doctors if that information was made available to them. And beneficial to you, because that device could be improved to give you a better, more informed diagnosis. The question is what do you care more about, your health? Or your insurance premium? EDIT: Of course you would want to anonymize it, but you could only go so far while making it still useful. If you unfocused it to a neighbourhood, insurance premiums would go up for bad areas, and the housing market would fluctuate with the health of it's residence. On the upside, cities and landowners would be incentivized to now care about the health of their residents. So ¯\_(ツ)_/¯
