Anybody who is willing to (A) Track their personal biological information, and (B) willing to upload this information to a third party, is utterly unconcerned about an aggregate graph like this. Your meta point, though, that people should be concerned about this type of tracking is well founded - but, honestly, I'm probably a lot more concerned about how easy it is for my cellular provider to track where I am at any given instance with my Smart Phone - (or any cell phone for that matter) - as I don't recall ever "enrolling" to provide them with my tracking information.
