Because of that, in the last four years, unbelievably many different things and especially travel have become possible. I also had the opportunity to meet many interesting and good-hearted people. All this wouldn't have been possible without our loyal audience and the wonderful management at our hands. 🙌🏼❤️." Zimmermann noted that it was "time to go a different route" for the time being, noting that the decision "wasn't really easy," but he felt "relieved." "With the successful outcome of my deep brain stimulation last September, the symptoms of Tourette's syndrome could be minimized and thus more things became possible from a professional point of view. 🔌🧠," he wrote. "That's exactly what I use now too. And so the chapter 'Storm in the head' finally comes to an end for me. I will remember the past few years though, with all the ups and downs." Zimmermann shared that Lehmann would continue to "stay active on social media" and manage their channel. "Thanks for [a] wonderful time," he concluded, "do a good thing🙌🏼💯💙."
