No. I can already spot numerous chronic medical issues in people and it would be rather awkward and rude of me to start scaring them. They may already know and if they don't it's not my place to be starting those conversations. That should be between them and their doctors. Consider instead making a device people can buy, install in their homes or bathrooms that can scan them on demand when they push a button. Make sure this device does not require an internet connection. Alexa, Siri, Cortana and the like need not be involved in medical diagnosis. Loose lips sink ships and the companies that make IoT's that leak patient data Instead of an internet connection, have a USB port that allows uploading updated data-sets to train the device. The device must always use the word "may". e.g. "Scan indicates that the patient may have the symptoms of ... but check with your doctor." and give them a way to save the results to a text file on USB that can be printed out for the doctor. [Edit] I should also add that Google received quite a bit of blow-back from their google glasses, to the point anyone wearing them were referred to as "glassholes". IIRC this also led to some altercations on public transit. At very least your device would have to appear as bog-standard glasses.
