Are things breaking down or is it all in my mind?

We have been on the road now for 33 days and the blisters are getting bigger. My feet ache at night and there are other pains I notice on a daily basis. Jo is also getting aches and pains.

While walking along I start to wonder if all the aches are real or is it that as the days go by my mind has lost interest in the surrounding scenery and is now concentrating inwardly on our bodies.

The blisters are physical and can be measured but aches and pains are subjective and can not be measured.
