Bob is a man still redefining himself after 60+ years of successes and failures.  He's a dreamer, a creator, a screenwriter, an avid reader and ironically intrigued with religion, even as a lifelong atheist.  He doesn't have a mean or angry bone in his body.  His story is one of close-calls, near misses, and yet he gets up, dusts himself off and looks for the next thing.  Gotta love him.
