Many phones are set up from the factory ready to enter ICE information.
My phone has ICE Wife Cell and ICE Wife Home. The ICE info comes up first when Contacts is selected.
That same information is on the cheap dog tag I wear on a neck chain 24/7.
I'd consider Road ID or some other medic alert tag if I had medical issues.
