> * my knees have improved so much that I feel like being 20 again. I no longer remember which one gave me so much trouble that I almost ended up in surgery in 2017. They are both just fine. I had shit knees when I was around 30. I started physiotherapy and going to the gym. This sort of worked a little bit, but what really eradicated all my knee problems was large volumes or running, jogging and walking. My plan was to start running, but since I couldn't really run properly for extended periods of time without pain, most of my "runs" were actually just fast walking. Now, about two years later, I can't really remember the last time I had problems with my knees.
