I have seen this on quite a few forums regarding scootering and motorcycling, I think it actually makes sense. It has been suggested that you program I.C.E (In Case of Emergency) into your cell phone. I have done this and have ICE1 which is my husband's cell number, ICE2 is my dad and both include My full name & address, contact info, drug allergies, current medications with dosage, blood type, health care number & GP's name. I have always carried this information on slip attached to my scooter insurance and there is one in my jacket pocket as well. It is really hard for emergency personnel to help you if they don't know who you are and this makes it easier for them to pull up your electronic medical records. So have you ICE'd yet? Tell me what you think of using this? Would you do it?
