BLOOD          :

               Slightly salty RED FLUID essential to the smooth

               operations of HUMAN LIFE. The RED COLOUR is due to

               the single iron atom in each of the large haemoglobin

               molecules in the myriads of red BLOOD cells.



               BLOOD is an excellent foaming agent. BLOOD from

               slaughtered cattle, bereft of its RED ness is used in

               some FIRE extinguishers.
