STORY HIGHLIGHTS

(CNN) -- As the politicians fuss and fight over the merits of the biggest overhaul of the health insurance system in this country, you may be wondering, "What does this all mean to me?" Here's what we know so far about what's up with your health care.

1. It's all about me

The Affordable Care Act, or Obamacare, as it is now commonly known, went into effect in 2010 and was affirmed by the U.S. Supreme Court in 2012, despite the 42 times the House Republicans tried to repeal it.

It will have the most dramatic impact on the 48 million Americans who don't or haven't been able to get insurance. By 2014, everyone -- with a few exceptions -- has to have insurance or face a penalty.

2. I get insurance through work. Why should I care?

More than half of Americans get health insurance through work. For those keeping score at home, that's 55.1% of the population, or about 149 million non-elderly people, according to U.S. Census data.

If that's you, news about Obamacare marketplace computer problems and people getting letters saying they're losing their coverage -- that doesn't affect you.

What you do have to worry about is that e-mail reminder your company sends you this time every year telling you about open enrollment season.

You may notice that information packet is a lot easier to read and the different plans are a lot easier to compare. You've got Obamacare to thank for that, since it is now mandatory that these companies communicate clearly about what they have to offer.
