I suppose I was being a bit confrontational there. Insulation and air sealing makes a huge difference, especially in cold climates like where I live, where it often gets down to -25°C or colder in winter. I live in a basement with very old, leaky windows, so the floor never really warms up. When I'm at my computer I tend to not move much, and in that position there's poor blood flow to my hands. I turn up the electric heater when I need to (electricity is very expensive here), but I normally rely on the gas stove at the other end of the house. I actually have no problem being outside when it's cold, and even prefer it over summer. The difference is that I don't stand in one position when I'm outside. When I'm outside I'm shovelling snow, turning a wrench, or walking.
