Dr. George Sheehan returned to the road at the age of 45 to become \u201cfully functional\u203f as a good animal. His book, \u201cRunning and Being\u203f became a philosophical bible for runners around the world.\xa0 In it, he taught us that this is our moment to live, and that we should not let life pass us by: we must run and be in order to know the total experience.
