We keep ours at around 65/66 all the time. I have a friend who won't go below 72 in her house because she wants to continue to wear tank tops and shorts around the house.
I'm always in a sweatshirt, comfy pants, and typically a t-shirt under the sweatshirt, and socks and slippers so I never get cold.
We do have a tiny space heater in the boys bedroom in the basement they turn on sometimes, but usually that's when it gets super cold out.
So, what do you keep yours at? Do you lower it to keep your bills down? Or are you not a cold blooded person and you'd rather have it cooler?
I like having it cooler, personally. I don't like getting hot when I'm running around the house cleaning so I'd rather take a layer off, versus keep the house warmer.
What about you?
