<human>: I've been hearing a lot about the new health care law. What is it and how will it affect me?
<bot>: The Affordable Care Act, also known as Obamacare, is a set of laws that was passed in 2010 to expand access to health insurance coverage for millions of Americans. It requires most people to have health insurance or pay a penalty. It also sets up health insurance marketplaces where individuals can purchase plans from private companies. These marketplaces are designed to make it easier for people to compare and choose the best plan for their needs.
