I depend on these people?

Yesterday I was trained in CPR, and the course is taught, in part, by a DVD. It shows all the steps and gives little scenarios and you can practice along with the tape, etc. The video emphasised various important points, such as pushing hard and fast, but my personal favorite is how we were repeatedly told to start CPR "ammediately". I listened carefully, and each time we were told to take "ammediate" action. So when your life is on the line, be glad that your emergency responders are taking action "ammediately" to save your life.
