What language do they speak? Is it different from the German? Is it possible to work there knowing only English? Why so many on bicycles? They can't afford a car because it's a poor country? Do they have ethnic discrimination? Do they have warm summers and how many month they last?
Danish, yes, yes, infrastructure and society supports that, Yes they can, and no its not, no they don't, yes, around 2 months. I hope that answers your questions :)
