One of the troublesome things about living in the brave new health care world is keeping track of all the bodies that, thanks to President Barack Obama, have new powers to govern your daily life. For instance, have you heard about the United States Preventive Services Task Force? No? Well, they’ve heard of you, and they’ve already got some plans. Don’t worry—you’ll know what they entail soon enough.

Even at 3,000 pages, much of President Obama’s health care law is very vague—it’s more about assigning authority for making decisions than anything else. And as of September 23, a great deal of that authority now rests with the USPSTF. It’s a federal advisory committee made up of 16 volunteers.
