Fell down the proverbial Ted-Ed rabbit hole this morning. I thought this was a great, quick and fascinating video, about how our brains are superior to non musicians
(kinda). That's the take away I got anyway, YRMV. Pretty cool none the less.

So if the more I play the smarter I get, why am I not a genius yet cuz I've been playing forever?
I realize you’re kidding, but I think it’s more a question of reaching whatever potential we have.
Looking around this very forum, there are an awful lot of bright, successful people.
