Thank you for writing about the choking incident. This was the first report from a "regular person" that I've read indicating that the Heimlich maneuver really works.
Most people don't really think about choking--how easily it can occur and how tragic the consequences can be. I know, because my mother once had a piece of meat lodged in her windpipe while eating at a restaurant. My father, who was a very quiet, unobtrusive individual, stood up and said (in a very loud, panicky voice), "Is there a doctor in the house?" Fortunately, there was. He came over, reached down her throat, pulled the meat out, and saved her life. This all happened long before the Heimlich maneuver was discovered.
