It's not just Facebook collecting your personal information. Health insurers know all kinds of stuff about you and if you're a couch potato, your rates will be higher.
Dr. Dean Sittig is a professor at the School of Biomedical Informatics at UT Health.
"They're not supposed to charge sicker people more money for their health care."
Dr. Sittig says it's an issue Obamacare tried to address.
"That's one of the things the Affordable Care Act tried to do; make it so that pre-existing conditions and everyone was entitled to purchase health care insurance at the same rate."
Dr. Sittig says if insurers find out you watch too much TV or you have bad credit, you will be charged more for health insurance.
He says one factor insurers consider is where you live.
"People are generally healthier in Colorado than they are in Mississippi (so the theory is) they should be charging people in Mississippi more for health care insurance than they are in Colorado."
Dr. Sittig says the current administration is doing as much as it can to dismantle the Affordable Care Act.
