The first 5 minutes of this video are an introduction, and an establishment of the Nurse's credentials. It isn't until about the 5 minute mark that the subject kicks in.
If you want to get to the meat of the video, fast forward to the 5 minute mark.
By the way, this video was sent to me by a friend of mine who is not at all in agreement with what we do here at IBA. And, his wife is a nurse. Somehow, we find agreement on this issue. And, as I said, his wife is a nurse.
I will ask him what his wife thinks of this video.
