Hi!! My name is Nancy, I'm from Mexico, regarding the question if we can live a week without a cell phone. 

Yes, on vacations where they give me 1 week, what I always do is turn it off and take it with me. The vacations are really for me to enjoy and see through the eyes and not through a cell phone.

I prefer to tell my friends or family to take photos of me and then pass them to me. 

Although I know that my relatives are not going to do that, not even my friends, at least I tell them to leave their cell phone in a bag when they eat, even if they are anxious to grab it and sometimes they even thank me.
