When I was a young child, I used to love eating slices of tongue. It was a cold meat that I really enjoyed. In those days, I never thought about the name of the meat, that is ‘tongue’.
When I was about 10 years old, I put ‘two and two together’ and realised that what I had been eating was once a living animal’s tongue. This realisation put me off eating tongue. I have hardly ever eaten tongue since that discover of what is in its name.
The curious thing is that, with plenty of knowledge of anatomy, I have no difficulties eating, say, liver or pancreas (‘sweetbreads’) or stomach (‘tripe’).

I get this 100%! Same with me!
Ah! Now you mention it, I remember eating tongue, too. It was a lovely soft and tasty meat, sometimes used on thin picnic sandwiches, with a little Colman’s English mustard. Where has all the tongue gone?
I don’t know but I am not missing it!
