What a story this is! A six-year old girl in California probably saved her friend's life. I can't imagine doing this when I was six, which shows just how amazing this was, but the girl did the Heimlich Maneuver because her friend was choking on an apple, and the piece of fruit came flying out, allowing her friend to breathe again.
Incredible. What's even more unusual is that the girl said she learned the Heimlich from watching a show on the Disney Channel.
We've always heard so many warning about doing the Heimlich, because obviously you want to help a friend and not harm them. Here's some good info from the First Aid Guide here at About.com on how to do it the right way.
