Four Pounds of Dust
Who knows when we last did that?
That thing weighs four pounds. Imagine if we never vacuumed. Four pounds of cat fur, human fur, dust mite corpses (and--EW!--their feces), dead skin cells, and heaven knows what else would be distributed in a half inch layer (I'm extrapolating) over ever surface and in every crevice in our house.
Food for thought. Or perhaps not.
