During the aftermath of Hurricane Sandy, we spent several days disconnected and it was really good.
I liked the more direct connection my wife and I had, talking more, doing retro stuff like playing cards (with actual cards!).
But I was glad when the power came back on.
I do have to take part of each day to turn it all off. Especially the cellphone. People get annoyed, because I often forget to turn it back on!!
But I'm confident I could handle a world with no electronics just fine.
