ICE your cell phone
The ICE Campaign was started by East Anglian Ambulance in the UK, whose staff often found themselves trying to figure out who to contact when they were called to an emergency and the patient was unable to tell them. If you were unable to tell others, who would you want others to contact you "In Case of Emergency"? Vodafone jumped on board the campaign in April, and PC Magazine explains why it's better to ICE your phone than just expect emergency workers to look for mom's number.
