Yeah, there's actually a lot of correlation between ignorance and bliss in my experience. Also between intelligence, reason, and anxiety/depression/both.
I'm not asserting that there's DEFINITELY a causative link, but I'm not saying there COULDN'T be something to it either 😉
Then again, there's also a shitload of correlation between ignorance and fear and interplay between curiosity, knowledge, and joy, so idunno 🤷🏻😁
