“One theory is that #LoseYourMarbles is related to the game of marbles where players try to knock each other‘s marbles out of a circle. If a player loses all their marbles, they are said to have “lost their marbles” which may have led to an association between losing one‘s marbles & losing one‘s mind.”
I have read some of Ahern‘s books, but not this one. I imagine if a marble collector lost marbles-it could drive them a bit crazy.
