I have new essay is up at The Nervous Breakdown. It begins:

“Despite my titanium hip, and the foot problems from years of marathoning, despite my tender back–one slipped disc–and the general wear and tear on this 55 year-old aging-athlete’s body, I (still) like walking. It does not escape me that my ancestors trekked from the savanna plains of Africa over 100,000 years ago and never stopped. It comforts me that, as a species, we have walked virtually everywhere, planting our feet on most every single spot planet earth has to offer.  It comforts me too, that despite the automobile and the jet, the boat and the train, our first inclination is to get up and walk. I do not take walking for granted. Over the years I have occasionally been in traction, on crutches, in pain or in some other way disposed of my ability to walk. When this has happened, I pretend that I will never walk again. I do this, like thinking of sickness when I am perfectly healthy, as a way to remind myself not to take walking for granted. (This is not unlike the Buddhist practice of going to the cemetery to remind oneself that one day it will all come to an end.) There are a lot of people who cannot walk and I do not want to be one who forgets this.”
