that's an example. >> doctors are addicted to mris, hospitals are addicted to mris. how do you tell people you are not going to get an mri every time. >> what we have to do is change the way we think about the medical care but also change the incentives structure. after all, if someone orders an mri, there's a lot of money to be made here. we need to get doctors focused, keeping him healthy and doing the appropriate care first, then only the major interventions afterwards. that's how we have to change how we pay for care and incentivizing doctors to keep patients healthy. it's an element of the reform, correct. it's not the only thing. >> of course it's not the only thing! you are so argue mentive.
