<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, also known as Obamacare, was signed into law in 2010 and went into effect in 2014. It requires most Americans to have health insurance, either through their employer, a government program such as Medicaid or Medicare, or by purchasing private plans on an exchange. The goal of the ACA is to provide more affordable access to quality health care for everyone, while reducing costs.
