alt Hacker NewsAnother article from that substack.com - this website has terrible UI, please stop using it. And I noticed that usually if an author uses substack - the article quality is bad.
Regarding the topic - "more brain activity/connectivity" does not automatically prove better long-term intelligence or brain health.
I think the article offers some good advice, at least advice that the author believes in, and from my own anecdotal experience it seems to hold water. Writing by hand, on physical paper, does indeed seem to offer some advantages over typing or using a tablet/stylus.
