I haven't heard about mitochondria in so many years (obviously. why would I?) and I can't explain why it feels so good reading this now.

I don't remember hearing that specific phrase in school. I remember hearing a teacher tell us to take deep breaths to fire up the mitochondria but not that it was "the powerhouse of the cell." This was a meme that became common after my education was done. Because it became a popular meme it's possible more teachers said it specifically along with whatever other fun phrases they had.

I have met multiple people from across the USA who specifically learned about "the fertile silt of the Nile river delta."

The book is on the table.

It’s “its”, not “it’s”, unless you mean “it is”, in which case it is “it’s”.
