I cannot fathom how an old couple manages to maintain a 5 bedroom, 3 storey house for just the 2 of them. Maybe a handful of times a year the house is full with family. It just seems like a lot of air to heat/cool, a lot of furniture that doesn't get used, a lot of appliances and land to maintain, and a lot of wasted room in the house when they probably only use a kitchen, bedroom, and living room the majority of the time.
