feet)– the blood pressure

              on the head bending
              down from such a height

              becomes very great. If a
              human being were

              exposed to such high
              blood pressure, his

              brain          would
              immediately burst.

                 This being the case,
              how do giraffes

              drink water without
              having      a     cerebral
                                                                                         39
              haemorrhage? That is because,
              Allah, the Creator of space, the sky, the

              earth and all creatures, has placed a very special mechanism inside a
              giraffe's head. There are little valves inside the veins of a giraffe's

              head. Once the height of a giraffe's head changes, these valves start
              to operate and prevent high blood pressure in the head.

                 Well, have you ever thought about why giraffes are speckled?
              This aesthetic appearance, in harmony with the grasslands, makes

              it hard for their enemies to distinguish the giraffes. Despite their
              giant bodies, they can thus hide from the king of the savannah,

              that is the lion, their foremost enemy.
                 In moments of danger, giraffes run at speeds of 55 to 60

              kilometres (34 to 37 miles) per hour. When they begin to run, they
              move their heads back and forth like a pump, and curl their tails.
