Paul... thank you so much for sharing that document ... it is 
totally fascinating reading !!    the author must have spent a 
lot of time figuring out the analogies for all the statistics 
provided.  :)     So engrossing, that all my plans for the 
afternoon came to a halt as I couldn't stop reading.
