"Sir, we see your REM sleep is not being fully entered into most nights. Our system has indicated that you buy caffeine and pizzas multiple days a week. This will be reported."
"Sir, we are denying your life insurance application because our insurance "partners" have determined you are a risk we cannot afford."
Etc., etc.
I will never willingly wear a tracker that reports health data. I will never willingly be chipped. Nothing of that sort. I always tell people to pay cash for their peccadilloes. Never use "loyalty" cards, as the info is sold to all manner of companies, including insurance companies. Banks sell "anonymized" data about your buying habits as well. And no one seems to be anything other than completely and utterly apathetic...
I just duct tape mine to my dog while we play fetch.
I would guess that if this gets mainstream, insurance companies may purchase user data from other apps to cross-check users lifestyle and deny claims where the user appears to be jogging on the insurance app but sleeping according to the totally free and fun sleep tracking app.
