Handiwork: How busy hands may help the brain

Researchers think activities that occupy our hands, like folding laundry, doing yardwork or knitting, are actually making our brains happier. Tony Dokoupil talks with Dr. Kelly Lambert of the University of Richmond, and author Matthew Crawford (“Shop Class as Soulcraft”), who’s never happier than when he is tinkering in the garage. Dokoupil also tests out the theory with artist Zaria Forman, who concocts vivid paintings without ever putting brush to canvas.
