We learned W= F x d or work equals force times distance.
Like other posts, this could have been in the women's forum, but guys have many thoughts and ideas too. Please just help explain how cleaning a ref and putting back items, or working at home like getting items from the ref, slicing near the sink, cooking on the stove, setting... then clearing again, putting leftovers on the ref again, is work. One can get very tired, but where's the work gone? Maybe it's been asked before, but i havent seen. Thanks for your patience.
