the USB with your medical files has been around for a while.
If someone want to be an asshat and put a virus on it when doctors are trying to keep them alive. They might find themselves dead. Pretty stupid to take that risk when their life will be on the line.
I have a USB Drive that has all my mother's medical information. So the next time, she has a stroke or worst. I can give the doctor's the USB drive and it will have everything they need to know. Meds she takes, when she had her strokes, etc etc etc.
