TIL “Cesare Marchetti observed that Greek villages and ancient walking cities, as marked by ancient city walls, tend to share a radius of about 2.5km. Walking at a typical 5km/hr makes a one-hour round-trip journey. He also pointed out that: “Even people in prison for a life sentence, having nothing to do and nowhere to go, walk around for one hour a day, in the open.”” Marchetti's constant is the idea that people throughout history have budgeted, on average, about an hour a day for travelling. https://images.prismic.io/sketchplanations/d9cae19f-2377-422c-be8e-4a580789bb04_180474637321.jpg https://sketchplanations.com/marchettis-constant
