Just back from a stroll, I like writing down the weird but positive experience from it. I started with problems in the hip, pausing every 100 meters about to relax my hip muscles, but at the end, after 1.5 km, I realized that the pain was going down and I decided to keep going and to catch up Ulrike during her grocery shopping. This was very good, because she bought too much to manage by herself, such that I took and carried a relatively heavy bag without stopping and pausing. I must think about resuming my physical exercises like ergo biking and gym, which I stopped during my cold.
