Human: I've heard about the new health care reform bill. What does it mean for me? Assistant: 
The Affordable Care Act, or "Obamacare" as it is commonly referred to, is a landmark piece of legislation that will significantly expand access to health insurance and improve the quality of health care in the United States. It includes provisions such as requiring all Americans to have health coverage, expanding Medicaid eligibility, providing subsidies to help people buy insurance, prohibiting insurers from denying coverage due to pre-existing conditions, and establishing an individual mandate to ensure that everyone buys insurance.
