Brook your ire Sir!
Sorry, I've been wanting to use that since I saw "Mr Turner", and your invocation of ire early on gave me the excuse I needed.
A nicely argued article. I'm particularly drawn to the "calories expended in keeping warm" as heat production is a major consumer of the body's fuel.
Anyone care to do a few back of the envelope calculations on heat balance for living in a centrally heated home vis-à-vis the "frozen window pane bedrooms" of the 40s and 50s?
