This is a simple technique to save yourself if you are alone and choking. IMO, it's much, much simpler and more effective than the variety of self-applied Heimlich maneuvers, which have been shown not to work for all people in all situations. I checked to see whether or not this topic had already been posted by scanning the last 10 pages on this thread. It hadn't. If you like this technique, please show this video to all your friends and loved ones.
