Yeah, actually, I learned runes and Tengwar back in the 1990s, my brain was a lot more plastic back then. While I didn't mean for this to get dark, PTSD sort of short-circuited my brain and I suspect that's why it's harder for me to learn new alphabets now, I have some other cognitive difficulties that didn't start until my PTSD got really bad so I think that probably went along with them.

That's interesting that the top 5 in your Diamond League is mostly monoglots. I wonder why I keep running into extreme polyglots in my Diamond League...
