Yes, I survived a few emergencies before cell phones! Somehow, we were able to survive (just like our parents who never wore seat belts or put us in car seats;only kidding). If my phone isn't on, they can call home and leave a message and I'll get it. My husband does not have ICE in his phone, but he does have HOME. Well, HE leaves his phone on 24 hours a day, so I guess that makes up for my lack of wanting to communicate.
