The man who views the world at 50 the same as he did at 20 has wasted 30 years of his life" -- Muhammad Ali.
In fact, let's go back more than 30 years and do it honestly. In 1974, Muhammad Ali was not a revered figure in my home in Huntsville, Alabama. There were no pictures of Ali on the wall; and if there had been the picture would not have been the famous one of a brash young Ali towering over a fallen Sonny Liston, but the one of Ali on his back, betassled boots in air, after Joe Frazier knocked him down in their first fight at Madison Square Garden.
