BY DOING THIS RANDOM THING OF WHAT APPEARS TO BE ABSOLUTELY NO MEANING, YOU HAVE GIVEN THE CELLS IN YOUR BODY THE CHANCE TO WORK, LIKE THOSE PEOPLE THAT SHOVE COAL INTO STEAM ENGINES, RELEASE ENERGY INTO THE ENVIRONMENT, AND ALL SORTS OF OTHER STUFF I DON'T REALLY KNOW HOW TO EXPLAIN!! The action that is seemingly meaningless to YOUR eyes is all-important to the eyes of CELLS and ENERGY, and for a brief while, is the VERY THING THEIR EXISTENCES REVOLVE AROUND!!
