Inactivity Timmer To Auto Save And Close Excel

I have a workbook that many users share. Sometimes for reasons unknown the workbook is left open. Sometimes typed data is lost from people not saving before closing the book. Any way to set a timmer that save and closes the book say after 10 minutes of inactivity? Any help id appreciated.
