Agatha Christie: On the gray cells (or neurons, or what ever you care to call them)

“These little grey cells. It is up to them.”

(From The 1920 book The Mysterious Affair at Styles. It was the first book that introduced the character of Hercule Poirot.)
Agatha Christie (1890-1976) Discuss
My take on this is another quotation:

Mens Sana In corpore ( “A sound mind in a sound body.”) It is derived from Satire X of the Roman poet Juvenal (10.356).

My phrase in relation to Agatha Christie’s grey cells, and Juvenal’s Satire X (10): “Remind your grey cell, that they reside in your body, remind your body that it has a brain and willpower.”
