I don’t normally comment on the photo of the week – after all, it is about the photo and an explanation should, for the most part, in my opinion, not be necessary. Dirty knees may not seem to fit the bill for endurance, but please you, me, they do. I have some serious issues with my feet and doing any physical labor while standing can be extremely painful. So, these are the knees of endurance – building a retaining wall in my back yard. Not a marathon run but after a couple more hours, endurance was what it all became about.
