I would rather just burn the gas and keep the house at 17 so I can walk around wearing my preferred house garb of just an old housecoat with no belt. My extremities excluding my hands and feet get too cold below 17.
If your garb is JUST an unbelted housecoat there is indeed a risk of cold extremities and not just hands and feet. Now pardon me while I clean the "mental images" screen. I should probably have caveated my remarks with "if appropriately dressed"!
Technically I said extremities excluding my hands and feet because my hands and feet don't get cold. My nose does. What did you think I was talking about?
