* Your health insurance company raises your monthly cost because your supermarket and financial data indicates an unhealthy lifestyle.
* Your search history indicates you have health issues since you googled symptoms, data correlation indicate a high chance of it being a serious condition, your employer determines it’s time to lay you off since you’re going to be sick soon anyways.
* You get denied a loan since the bank deems the risk too high based on your Amazon purchase history which indicates poor impulse control.
* Plane tickets and hotel bookings are 10% more expensive since you visit the site from an expensive computer and have a history of being interested in luxury items.
