What will you do when you stop working?" a colleague asked me nine years ago. I didn't have an answer at the time. But I realized that I should find a new job in good time. Shortly thereafter, I stumbled into one while watching TV Interview about running therapy. I heard the term for the first time, even though I was a runner myself. I knew immediately: "That's it!" And so I soon started training at the German Running Therapy Center. At the same time, I quit my permanent position as technical director and set up my own engineering office so that I had more time for my new heart project.
