On NPR.org: "Overshooting Obama's Health"

New writing of mine, posted elsewhere (and broadcast on All Things Considered on 3/4/10):
"It doesn't take a CT scan to know that President Obama should keep exercising, watch his diet, and quit smoking. So deciding not to do a test like a coronary artery calcium CT scan isn't just about avoiding the financial cost of the test. If the results of the test won’t change what we recommend, then the patient is taking risks for data that won’t make a difference."
