Got this from an acquaintance in the UK today. Brilliant idea: important, and cost-free, and just needs everyone to be "on the same page", so to speak:
Following the disaster in London . . . East Anglian Ambulance Service have launched a national "In case of Emergency ( ICE ) " campaign with the support of Falklands war hero Simon Weston. The idea is that you store the word " I C E " in your mobile phone address book, and against it enter the number of the person you would want to be contacted "In Case of Emergency". In an emergency situation ambulance and hospital staff will then be able to quickly find out who your next of kin are and be able to contact them. It's so simple that everyone can do it. Please do.
Please will you also email this to everybody in your address book, it won't take too many 'forwards' before everybody will know about this. It really could save your life, or put a loved one's mind at rest. For more than one contact name ICE1, ICE2, ICE3 etc.
