Let's go back 181 years to 1844-The Fist was the slang term for trained telegraph coders' messaging style.   You were said to have a "good fist" if your messages were steady in touch and speed and rhythm.  Coders came to recognize "the fists" of their fellow coders......important in case an imposter commandeered a telegraph station!

We humans run in circles, but our technology progresses in a straight line.  Ah! There's the rub!

Every past era was "modern times" once.
