Millennial here. I got a degree in Classics so I learned both in college. I continued to take Latin in grad school. Unfortunately I never used them, because, you know, there are no jobs in Classics, so I realistically have lost both. I could probably identify nouns/verbs/articles/etc and some vocabulary in a sentence. But that's it. Plus, I'm learning Dutch now, and that has kicked out all other languages rattling around in my head.
I really enjoyed learning both! And doing so taught me a lot about grammar, linguistics, and etymology that I've carried with me through life even if the languages themselves didn't stick. Would recommend if you have the time.
The blue in this really works for me. Love it
