Orthogonal issue but here is what I think -- While I agree that privacy is of great concern, I do think the way to approach this would be with more frequent health checkups. 
Our body is the best marker at the end of the day to measure our healthiness. Everything else doesn&#x27;t matter, which is also the reason the allure of wearables is wearing out. (It&#x27;s great, but what do you do now that you have all this data that you have gathered?)
