Alleycat opened this subject on September 25, 2021 by referring to a similar-titled article by Mr Roger Skoff.  The contents of said article merits further discussion  but I was sadly not available at the time to contribute. I now quote most of the article with my comments in blue:

I apologise!  Owing to a computor fault the piece I wished to quote has disappeared!! 
I will continue as soon as I am able to relocate! (See time of night!)
