CPR

Each year in our office we have to take CPR recertification. Tomorrow Bill has to go to class and take a test too. I heard there have been several changes since last year. Sometimes I wonder why there are so many changes. Is there really a need to change things? Doesn't the old way work any more. Is it so more booklets can be printed? I don't know the answer but I do think it is worthwhile to go through the class periodically. It is always a good refresher.
