My neighbor installed a heat pump and sealed up all the cracks in her house. She never has to dust. I heat with propane and wood, my dog and cat go in and out of their own door all day, not to mention myself/my own door, and I live at the beach, and the wind blows a lot. My house need to be cleaned all the time. She gets a lot more done in her life than I do in mine and I now see that THIS IS WHY. GRRR.
