Uphill both ways
From the window in our room in the Chiado quarter of Lisbon, we can see the Castelo de Sao Jorge on the hilltop a couple of miles away. It’s visible from various places in this city because of the many hills. These hills contribute to the beautful landscape, but they also make walking quite trechorous, Each time you turn a corner, you’re faced with a decision: Up or down? Which muscle gets the workout? We invariably choose up, thinking of how much easier it’ll be to backtrack. Somehow, we always end up walking uphill both ways. How does this happen?
