He still worked part-time 40%, or he still works 40%. That means that on working days he could do everything on his own, for example go to M [place] and do the work. He could do all that. He told me that it just took more and more strength. It took a lot of effort, but he could do everything himself. He always wanted to do it, even difficult things like putting on shirts, although he was already worse, he never wanted to accept help. He rarely did that. He could still work independently, but he had more and more trouble, for example with walking. He told me that he used to drag himself from the train station to the office in M [town], because it was getting more and more difficult to walk. That started about two to three years before the deep brain stimulation. Then he still did a lot of sport, kayaking, hiking. And then, of course, there were some restrictions because he suddenly could no longer move.
