I’ve got to write these links quickly, before my fingers freeze altogether and I’m left tapping icicles on the keyboard in an attempt to make my points here. It’s about -3 degrees centigrade outside (about 26 Fahrenheit), and before the Americans and Canadians burst out laughing, our houses are not built for this: poorly insulated with random gaps to allow the ingress of small critters and cold air—though thankfully it’s only the cold air I’ve had to contend with here.
