While I don't think I'd want to unplug for six months like the family in the book The Winter of Our Disconnect by Susan Maushart, those brief times when I do unplug (or my whole family unplugs) are a wonderful reprieve from the chaos of life. It gives my body, mind and soul a break, a rest, and a different kind of recharge.
I am seriously inviting all of us, at some point during the summer, to unplug. Whether it be for a day, a weekend, a month or more - just leave the technology and all the "screens" behind and see what happens. It really might just be the best part of your summer :)
