Walking is truly great, but it's not uniquely magical. Most of my best ideas have come on long drives. I believe that driving has a lot of the aspects of walking that lead to the ability to have ideas. The activities themselves (the need to avoid running into other cars while driving or tripping over something while walking) seem to involve just enough distraction to keep you from falling into a rut of repetitive thought, while still enabling a state of free thinking that you can take quite far into a subject. As for the time I could spend walking daily: I meditate daily for half an hour in a Buddhist tradition. And the rest of the time I could spend on daily walks I spend instead on medium-intensity aerobic exercise, which does more purely medical good than walking does and also is more associated with delaying age-related cognitive decline. (I need to add more HIIT which would help even more.) On the other hand, my wife and I are also planning a 2-hour hike for later today. Because walking is great. It's the weekend, and we can give ourselves that.
