In the phone book on my phone I have the first entry be my wife, and then list her name and then the words " - My wife". After the last discussion, I knew EMTs weren't going to be looking through my phone, but if the phone ever gets lost, it's a lot easier for a good samaritan to give her a call to let us know where the phone is. And if an EMT does look through my phone, I figure that will help just as much.
