 All right, now we've got Janie on the line who's calling us from Washington State, and she wants some help with a project for her 92-year-old aunt. What are you working on? Well, my aunt lives by herself still. She does very well for herself, and she lives in eastern Washington State where it gets pretty cold. She has a house that she's been in since 1963 when it was built, and she wants to see if she needs to upgrade the heating system because she's talking about selling her house.
