I don't know how old this article is. I remember reading a similar article not too long ago. Still, an interesting premise.

I find this sort of story fascinating......I have never met anyone else who shares my curiosity (shrug.)

I find the words that have reversed their meaning a bit more interesting as it changes the meaning when reading old stuff.

The word "cleave" is an example.
As late as the 1800's it meant to be "attached to."

Today the first thing that most of think of is "cleavage" with a meaning of a separation, a crack.
Thus a current dictionary gives the first definition as “separating.”
