Since the ice rink where I used to skate at lunch has closed for the season, I've slowly begun taking walks at lunch. Call it a nod to exercise, of which I get very little. It's been a good daily routine, and I've rarely missed it.
I take a left out of my office building, and walk across the Longfellow Bridge. In my routine, I walk to Boston on the west sidewalk, which is the narrower sidewalk. When I get to the other side, I walk back on the east sidewalk, which is the wider sidewalk. The views are gorgeous, even when the weather isn't ideal.
Mileage maps show the distance to be under a mile (.88 miles, to be exact). I get the whole thing done in about twenty to twenty-five minutes. Some days I'll walk briskly, but mostly I walk normally, affecting no rush. Sometimes I'll even stop along the way and take pictures.
The walk is good for the heart, supposedly, but I've been finding that it's good for the mind. The work that I do is quite immersing, so the walk clears my head. A little brain reset in the middle day. I recommend it, highly.
