After the party yesterday, we slept very long and we started breakfast about half past ten, if I remember correctly. After breakfast, I did some exercises as always, pedaling my ergo-bike and doing some exercises for strengthening my hips. After that, we had a walk with my son and my wife and surprisingly, I could walk the last 700 meters better than the first part of about 2 kilometers. In the afternoon, I continued my exercises by climbing the staircase in our house up and down, in total 28 floors. I was exhausted after that, but very happy that it worked better than I thought before. In the evening, I had a very long talk with my son in English (the first time in our lives), more than 90 minutes, and it was rather fluent. I was very proud of him as well as of myself.
