It is not all about work :-)
I am father of two wonderful children. I love to spent time with my family and friends. We live in one of the suburbs of Hamburg.
I love to ride my BMW S1000RR. And go on tours together with friends.
Each Winter I try to go snowboarding for at least one week. As former Snowboard Trainer I had the opportunity to saw a lot of Areas in the Alps in Switzerland, Italy, Austria and Germany. Each Area has it advantages, but my favorite Areas are Zermatt, Verbier, Saas Fee for Skiing. To hava a good time with friends, my favorite Area is Saalbach in Austria.
I love to work on my house and automate as much stuff as I can. We build our house in 2020 during the Covid Pandemic and since then I am working on it. I love to work with my hands and to see the progress. I still have a lot of projects, at the moment it is my Shed. My last projects were the irrigation system. I learned to drive an excavator during my Projects, it is still fun to work with it. The best thing on doing stuff with the own hands is to have an excuse to buy new tools.
