My thermostat is at 72 and I walk around shivering. The house is usually settled at 71.5-72.5. I prefer 74.
My thermostat is at 52 (hey, it's 8 outside) and I walk around perfectly happy (I took a nap today not far from the thermostat... with a couple of throw blankets over, of course). It's 56.7 in my office (upstairs, where I am now). Obviously I don't go barefoot and wear only a T-shirt, I dress for the weather. I'd much rather have it be too cold (can always put on more clothes) than too hot (there's a natural limit to how much you can take off)..
