Not medical, but mildly interesting, at least to me.
In a genealogy book, a man in about 1200 was convicted
of "misprision of knighthood". It took me quite a while
to figure out that this meant he got fined for trying to
avoid a tax on those holding that title, by concealing
the fact that he had been given the title.
From Brewer:
Misprision Concealment, neglect of. (French, mépris.)
Misprision of clerks. Mistakes in accounts arising from neglect.
Misprision of felony. Neglecting to reveal a felony when known.
Misprision of treason. Neglecting to disclose or purposely concealing a treasonable design.

From my dictionary:
misprision
n.
ME mesprision < OFr < pp. of mesprendre, to take wrongly < mes3, MIS31 + prendre < L prehendere, to take: see PREHENSILE6
1 a mistake, now especially one due to misreading, either deliberate or unintended, or to misunderstanding
2 scorn; contempt
3 Law

He was sandbagging?

No, he kept his dough hidden in an old sock just like
everbody else.

Well, if he kept dough in the sock instead of sand in the sock, he was doughbagging.

And he had to be very careful his wife didn't bake his socks.

Legend has it that Molly Brown burnt about 100,000 dollars her husband brought home and hid--I think it goes--in their stove. It's been a while since I saw "The Unsinkable Molly Brown..." but I do remember reading that the incident probably never happened.
