If something happened to you, would rescuers be able to figure out who to contact? Probably so if you have your family listed in your mobile phone directory as "mom and dad" or "home" but what if you have important numbers listed only by name?

That way, rescuers, police, and hospital staff can quickly contact a family member or friend on your behalf.
