Just a side note: When I retired a year and a half ago, I couldn’t walk 1.5 miles without a break or two if any incline was involved. So I started walking. And walking. I have no idea what kind of weight loss this trek will do, but with the walking and very little attention to caloric intake, I was down about 40 pounds before I left. Persistence and consistency. In very small increments. And I can do this. I don’t go as far or as fast as I would have at 62, but 72 is doing it.
