I wonder if any of the benefits of walking carry over to biking? I've basically given up walking to always biking but after reading "Deep Work" I'm starting to feel like I'm missing out by not rambling around and zoning out.
P.S. a) It's easier to dawdle when you walk, to enjoy the particulars of the places you pass; biking is so fast by default that you have less time to savor details. b) Biking tends to be higher intensity exercise, which may actually take necessary energy away from mind-wandering; in fact, my mind wanders much less while biking than walking, so I'd guess this is the case, but maybe this isn't true for everyone. Moreover, biking forces external attention more regularly as you encounter pedestrians and traffic at a higher rate
