1,300 Years Old Medieval Flush Toilet Discovered in South Korea

. . .

   The IDEA of a 'flush' toilet actually seems to
   be a very OLD one. It was mostly a matter of
   the fine tech, and water/pipes/$$$, that defined
   whether you had 'em or not.

   They WERE known in old Rome - almost 2000 years ago.
   Kinda exclusive to the Very Rich, but they HAD 'em
   in various forms. Probably had 'em in old Egypt
   and Babylon too for the Top People.

   TP, on the other hand ... that TOOK awhile. Mostly
   it was the proverbial 'stick' ........   :-)
