I'm a little confused by the new health care reform bill. Can you explain it in plain English?

The Affordable Care Act (ACA) is a comprehensive set of reforms to the US healthcare system, designed to expand access to affordable insurance coverage and improve quality of care for all Americans. It includes many different provisions that affect individuals, employers, insurers, and states. Here are some key points: 
1. Insurance companies can no longer deny coverage or charge higher premiums based on pre-existing conditions.
2. Insurers must provide coverage to children up to age 26 on their parents' plan.
3. All plans must cover preventive services without charging extra fees.
4. Medicaid eligibility will be expanded to include people with incomes up to 133% of the federal poverty level.
5. Health insurance exchanges will be created to help individuals and small businesses compare plans and find the best deals.
6. States can choose to expand Medicaid to additional low-income adults.
