I too have slowed down this winter. Now I am not a real active person in the warmer weather alittle gardening messing with my fish pond ect. but arthur like my fish does not like cold. When the weather warms they move more and so do I. SO my thoughts are Fat is more plyable when it is heated other wise it is just sits there. I know on warmer day I even move better Spring is actually only 65 days away so we will be amovin soon.
