The "wow" factor of any puzzle trying to guess age disappears when it's almost verbatim the standard process of computing age from D.O.B. I tried to formulate a new puzzle with simple directions yet with inner-workings that are, hopefully, truly puzzling: <a href="http://thoreaulylazy.blogspot.com/2008/04/happy-birthday.html" rel="nofollow">new puzzle</a>.
