Saturday I walked the longest distance I have since surgery, roughly two miles. Before surgery, no problem; Saturday I felt weary with every step. One foot in front of the other to get the job done. Healing is real, but you don’t get further without a little push. I feel I have to be ready for long walks later this week, on my way to Wasington DC. Not sure how the new shunt setting will deal with the difference in air pressure while onboard the plane, always an adventure.
