I could survive without any of them, but I wouldn't call it living. I could give my electric can opener, hand mixer, land line, Cable TV, alarm clock, electric griddle, crock pots, dehydrators, electric toothbrush, away and even my sewing machines and sergers away and not be put out too much. I have two treadle sewing machines, a hand can opener, a whole bunch of cast iron skillets and a few stock pots, regular tooth brushes and I can can and make jerky and dry fruits without the dehydrator. We are so spoiled aren't we?
