No me creo superior pero creo q hay q ser wn pa creer hoy en dia en un supremo todovidente omnipotente . Lol <| sep |> It ' s sort of a trick problem . One of the few things I remember in my Physics class is that if you end up in the same place as you started , you ' ll have done zero work . It has nothing to do with the energy used to move your body , calories burned , etc . I know someone here can school me on this and help enlighten us both . All I remember is that you have to be at a different place to have done work . It doesn ' t really make sense to me as you can ' t possibly be in the same place as before , as the Earth is moving , the Galaxy is expanding , etc . But I believe for this purpose , it effectively communicates the idea that hard work doesn ' t equal progress .
