So many of our fictional heroes, from Tarzan to James Bond, are variations on the superman theme. Here is the true story of a man who realized that myth: Joseph Greenstein, The Mighty Atom. He was a modern-day Samson who could stop bullets and hold back roaring airplanes, a man who rose from the Jewish ghettos of Poland to become the most remarkable strongman of the century. The Spiritual Journey of Joseph L. Greenstein, World's Strongest Man is a fully-documented and illustrated biography that also details the methods Greenstein used to train himself for the impossible. As a vaudeville star, he bit through iron bars, crushed steel spikes in his hands, and held back airplanes tied to his hair. These feats were all the more amazing because he stood only five feet four inches and weighed in at just 145 pounds. But The Mighty Atom had developed his own technique for tapping into the life-force; a technique that encompassed Asian methods of concentration, Jewish mystical writings, and a then-unheard-of vegetarian natural diet. He unlearned the subconscious mechanism that forces us to stop when we think we have reached our physical limits. Each time he broke an iron chain, he revealed the enormous potential of the life-force. That potential exists inside every one of us and, as The Mighty Atom showed, it is within our grasp.
