In about 10 days, the face of health care in America will change as the biggest part of the health care overhaul signed into law in 2010 takes effect with the opening of the federal Health Insurance Marketplace. The marketplace will offer those currently with and without health insurance a chance to see what new options for coverage are available under the Affordable Care Act, also called Obamacare. Some people will be able to remain on their current insurance if it meets the standards of the act. Some will be able to afford insurance for the first time.
