Don't get me wrong, I enjoy modern conveniences like heat, but my goodness! We have a wood stove, that I typically keep between 68 & 70° F. Comfy when preggo with all this extra blood and fluids. My mother, on the other hand, likes to feed the fire. All day. It is now 78°. I am in shorts and a tank top, have a fan on me, and am still roasting! In Michigan, in December, I should not sweat! It is 28° outside. I may just put on pants and go for a walk.
