I had a math professor from Nigeria

The dude spoke like 6 different languages, but when he first came to America, he barely spoke a word of English (which is how he ended up in math, numbers work the same in any language, and probably why he was really good at teaching math)

But the dude had seen some shit in his day, and we'd occasionally get some absolutely insane lore drops about armed militias and such rolling through his village, I'm pretty sure he spent some time as a child soldier, he'd occasionally get a little nervous if he heard a helicopter fly overhead, etc.

I'm glad he taught math, because like I said, he was really good at it, but man, I would have just signed up for a class to hear him talk about his life.

I had an engineering professor who grew up during the Iranian Civil War. He was interesting, and while the anecdotes were rare, they were crazy

iirc, it's the opposite of a doomer

I think, it's just used as in "late bloomer", so someone who needed a bit longer, but now found their true potential. "Bloom" as in the thing flowers do.
