I live in the city of the current Swiss Football champion (Bsc Young Boys). I want them to succeed again this season. The final reason is my little nephew. On my summer vacation visit, my nephew asked me what I do for a living in Switzerland: Software Engineering and Architecture for Distributed Computing. That was too abstract or vague for him.
