62nd and 23rd

I'm sitting here in that same old Dunkin' store facing the same scene I showed in a recent article.  There's a street sign right there ahead on the corner: NW 23rd ST on top facing in one direction and NW 62nd AVE on the bottom facing the other. Cars come and go, but I don't see pedestrians making any use of the provided sidewalks here.  That's a lot different from the Manhattan, NYC streets I see on my YouTube live feeds at night...click HERE to see an earlier video.  On them the cameraman, with seemingly endless endurance, walks a brisk pace for miles upon miles, up and down Midtown Manhattan streets and avenues...it makes me tired leaning back on my couch watching all the fast-walking people, and they, too, seen to possess boundless energy.  But were I there among them, I probably wouldn't be tiring either, no matter how much real estate I covered.  I've been wearing a FitBit watch for a few years, and when I was working (at the post office) the last couple of years I would almost always be in continuous motion, often deliberately walking when I probably could have just stood or sat still.  I would regularly amass more than 20,000 steps in a workday, and then when I got home as often as not I would do some running-in-place before going off to bed. Now that I am retired, am I unconsciously scaling down my physical activity when I don't have to? And if so, is that a good thing?  On today's neighborhood 3.3-mile walk/run, I originally set out to speed-walk the whole loop, but at the 5-minute mark I switched the project to 5 minutes of walking alternating with 5 of easy running...and it worked! Beforehand I had thought that running would be a little too rough, but I discovered that I could get into a nice groove for five minutes knowing that I'd be back walking some.  No problem...this is actually a step up from my earlier plan to institute a 6 minutes walking/4 minutes running routine.  So maybe this 5/5 system can get me through long distance races...the first half-marathon is coming in November.  Then in early December it's a 15K, followed in January by a choice I have between a marathon and half-marathon.  Let's see how far I can take this, in the old "postal worker/ big-city walker" spirit...
