Fact of the day: Dr. Charles Hellman’s team at the University of Illinois did a test on children’s heads, sent half of them on a 20 minute walk, and left the other half sitting quietly. They found that the walking group showed a measurable spike in a specific brain signal tied to attention and focus. The kind of neural activity linked to better test performance immediately afterward.
It’s the kind of finding Nietzsche would’ve recognized without needing a EEG cap. He wrote his entire final book almost exclusively on the foot, walking six to eight hours some days, and left behind a piece of advice that still holds up: sit as little as possible, and don't trust an idea that wasn't born in the open air, moving.
Your brain isn't broken when it feels foggy. It might just be sitting down.
