Bad sperm

According to 20 minutes yesterday young Swiss men have bad sperm, and particularly bad in Zürich. Why? No idea. Why it would be worse in a clean city like Zürich where people have one of the highest standards of living in the world is hard to guess. And this was in comparison to other countries. Well, for me it is good enough. Was just struggling to get on a bus with 3 (!) strollers, kids screaming and mothers who didn't give a flying fuck about the rest of us poor passengers. Bad sperm is a good thing!
