For many years the whole world believed it was impossible to run a mile (about 1.6km) in less than four minutes. Doctors and Scientists said it was humanly impossible. They said the confiduration of a man's skeletons and muscles did not allow it. Top athletes said it was impossible. However, Roger Bannister chose to ignore their comments and advice. He kept on training and stretching himself. On the 6th of May, 1954, Roger Bannister ran one mile in exactly 3mins, 59 seconds. He disproved the theories of the experts and gurus of his day. Oh we never know how much we can accomplish until we really stretch ourselves.
