I mean things probably will go that way as tracking of individual behaviors gets easier right? For example, I believe some healthcare providers will give free fitbits to users (I think the State of Nevada does) to get them to exercise more, so not a direct fee but they are incentivizing a certain behavior. Then you've got all the car insurers now that are looking at more details of your driving above and beyond the standard 1) how old are you 2) have you been in any accidents
