Glorified Fasting Hardcover
"There was a fencing master who never lost a duel. His movements were so swift, his aim so true, and his skill so astounding, that he was a source of amazement to all who beheld him in action. However, his secret was simple. Before any duel or engagement was entered into he, of course, would practice faithfully for hours. In addition, he would fast from seven to ten days."
