I am sitting just thinking of what you are doing Kenin. The Hands, feet, and the face, if you start to feel the hurting it is time to go inside and warm them up. It is hard not to sweat when working, having the right amount of layered clothing on and the right type of clothing on, will keep you warm and not over heat causing you to sweat. This is very difficult for me. It seems I sweat very easily in winter, spring, summer, or fall, when I am working.
