That's certainly fair. I was trying to use it more broadly, as people with ADHD or dyslexia can still hyperfocus on trains, boats and plains too.

But I did just outright forget that OCD can be considered neurodivergence instead of mental illness, in part because I've seen many people with OCD in my work who are on the mental illness end, the "I can't sleep because I need to flip switches in a certain pattern or else my family will die" situations.

Edit: Of course how much of mental illness is neurodivergence and how much is a separate thing I understand is also a contentious debate. Is it all? none? Specific things like bipolar or schizophrenia? Personality disorders? Etc
