This video gave me chills...and so it should.. Now I know why I have been so passionate about this material. And it makes so much sense as if you think, our ancestors had decked their homer out with rugs and throws from wool and they new the risks of open fire. very often they would have their kitchen in the middle of the room, right on the floor. Their floors would be covered with woollen rugs and that would make their homes warm and safe.
Small steps can make a big diference.
