Living without Electric what exactly?
Sorry but of the very few grammar errors that get to me, people saying "Electric" instead of "Electricity" is right up there, I am far from being great with grammar but that just grinds my gears.
Anyway, probably not very long but then who cares? This is the kind of thing I've never understood, yes you can live without electricity or by growing all your own food, however unless there is a nuclear disaster in which case we are most likely all dead we will never, ever have the need to, so "knowing what it's like" is about as important as trying to teach your son what it's like to not breath. We have all this electric stuff because we live in the age we live in, we are not "lucky", we are not "privileged", we just are, we live and electricity and all the lovely stuff that comes with it is part of that life, going without it is and insult to all those great scientists and minds of the ages who and worked to give it to us.
(Yes I am being purposefully over dramatic.)
