This afternoon, I took a taxi to Pena National Palace in Sintra. The driver was talking about the difference between walking and working out. He said something along these lines: “Going downhill is walking, going uphill is working out. You go downhill, you walk.”
“Okay,” I answered, “I’ll go downhill.”
I visited the palace and then I walked downhill to the town of Sintra. I happen to disagree with the driver; in this case going downhill was a workout as well.
