Short answer: Less Stress and More Happiness

Why I think so…? (From student perspective)

Germany is quite cheap as compared to other EU countries. No stress of thinking multiple times before buying something it’s manageable.
It’s quite safe here in Germany so no stress on roaming around late at night
Germans are very helpful and good people. Love to hang around with Germans.
Not so many things to do, have lot of time for myself and things I love to do.
