If I would have titled this post an "X" post, I would have all porno spammers as "anonymous" in my comments ! And as it would be a big deception for them I don't do it.
X stands for so many things ! For example if you buy a cloth size XL it means that you are a little extra large, but if you read XL as a Roman number it would only be 40, which is a rather little size in Europe.
In Roman numbers X stands for 10. Fortunately since the 14th century, Roman numerals were largely abandoned in favor of Arabic numerals ! Fortunatly, otherwise XXX +V would be 35 imagine the space it would take on a paper. Today you still find Roman letters for Kings and Queens (George V, Elizabeth II) There is no King or Queen who made it until X = 10 ! as far as I know.
X also stands for anonymous. "Mrs X and her lovers" would be an attractive book title.

You still find Roman numerals on clocks

And then why Malcolm Little who is not well known under this name, became Malcolm X ? In his autobiography, he explained why: "The Muslim's 'X' symbolized the true African family name that he never could know. For me, my 'X' replaced the white slavemaster name of 'Little' which some blue-eyed devil named Little had imposed upon my paternal forebears."
With all these Xplanations I wish you to reach the age of XC (90) at least !
