Blood is thicker than water
Not too long ago (12 October 2016), I wrote a post about the etymology of the verb bless and decided that my next topic would be blood, because bless and blood meet, even if in an obscure way. But more pressing business—the origin of liver (21 March 2018) and kidney (11 April 2018)—prevented me from meeting that self-imposed deadline. Today, Dracula-like, I am ready to tackle blood.
