I pulled out my medic alert tag on its stainless steel chain. The charge nurse turned a ghostly shade of pale. I had been wearing this tag around my neck day and night for over ten years just for this day and it failed.
When I was discharged and got home, I decided at this point in my life it was appropriate to wear my heart on my sleeve. I ordered a bright red Road ID wristband and have worn it every day since both on and off the road.
Not saying it did not happen as you describe it. But based on my numerous experiences, I have a hard time believing it did happen as you describe it. I've had Medic Alert necklaces and bracelets on for about 30+ years now. Dozens upon dozens of times they have been used. I don't recall them ever not being found by the treating paramedic or policeman or even citizens/passersby. When you are lieing unconscious, people automatically look for the Medic Alert necklace and bracelet. The necklace is found more often than the bracelet and the necklace is the first thing they look for. Medic Alert stainless steel necklaces and bracelets are known/recognized by everyone, everyone, everyone. Whereas the Road ID thing is unknown by everyone. Its just a piece of costume jewelry. Looks like one of those decorative Armstrong wrist bands.
