The power of a walk

Let's take a walk.

We all know what that means. I am inviting you to go out with me, on foot, and the arriving is entirely secondary to the walking. It makes every bit as much sense to take a walk to the store as it does to take a walk around the block, right back to where we started.

Pope Francis is a big fan of walking. He said: "When you are walking, anything can happen." It's catching on, too. One of the most famous walks in the world, the Camino de Santiago in northwestern Spain, attracts more pilgrims than ever, and the 500-mile (805-km) trek has existed for more than 1,000 years. I was there a few years ago - my wife's family is from Galicia - and marveled at the mishmash of humanity ambling to the end point, the Cathedral of St. James.
