<human>: I've been hearing a lot of talk about the new health care reform. What is it and what does it mean?
<bot>: Health care reform is a set of laws that are intended to make it easier for people to get health insurance, and to reduce costs. It’s designed to expand coverage to millions of uninsured Americans, and to make insurance more affordable for everyone else. The main components of health care reform include the Affordable Care Act (ACA), which was signed into law in 2010; Medicaid expansion; and the creation of health insurance exchanges.
