And there would be so many varriables about how one hand washes dishes. I've seen people who leave the rinse water running all the time they're actually washing the stuff in the sink full of soap.
So such numbers are to be taken, well, maybe with a grain of soap. I actually like washing dishes particularly in cool weather, and wouldn't give up the space for an automatic washer. but then there are only two of us, probably if we had rug rats I'd feel differently. like poor, harrassed and frightened! <GRIN> Tom Fowle
