:: Whats wrong with eating any part of the animal that's dead ?
Well for one rather obvious point for the general case, little fleas
have lesser fleas, so you're not eating a part of the animal that's
dead, you're eating a part of the animal that's dead PLUS potentially
all the lesser fleas that killed it, some of which may not be truely
most sincerely dead. Such as bactera, virussesses, prionses, etc.
Among others. Some of those have no reasonable/reliable sterilization
procedures that still leave anything edible. Or at least, nothing
palatable or nutritious.
Not that that's strongly relevant to nightingale tongue, but still.
And anyways, the upthread note was that it's "crass", not "wrong".
Even the french hide their act in shame when they eat ortolanses.
(Wikipedia says it's not an act of shame, but of courtesy, but
that still has implications of crassness...)
"Stickiness is the most underrated of all the nesses.
And of all the stickinesses, the sap of the maraca nut tree
is the sticky-nessiest."

"Powdermilk biscuits are made from whole wheat raised in the rich
bottomlands of the Lake Wobegon river valley by Norwegian bachelor
farmers, so you know they're not only good for you, but also pure,
mostly. They give shy persons the strength to get up and do what
needs to be done. Heavens they're tasty and expeditious."
