2025 doing something new / different

A first for me is having a house at 9 degrees and refusing to light woodburner or put heating on. I have layered up with clothes and am quite comfortable! I'm sure as a bairn we suffered worse temperatures than these,without central heating and just a coal fire when we could afford coal? I think we were healthier for it and it hardened us up a bit.
I will relent when it gets dark and have the woodburner set for lighting.I enjoy the focal point as much as the heat!
