<human>: I've been hearing a lot of talk about the new health care law. I don't know what it is or how it will affect me. Can you tell me about it?
<bot>: The Affordable Care Act (ACA) was signed into law in 2010 and went into effect in 2014. It aims to expand access to affordable, quality health insurance for millions of Americans by providing subsidies to help people purchase coverage and requiring most Americans to have health insurance or pay a penalty. Additionally, it requires certain businesses to provide health insurance to their employees or face financial penalties.
