I also particularly enjoy the "Germanic Stare Down"[0] culture; being free to look at anyone and in the eyes without that being considered hostile is something I consider healthy as well. Compared to other places where lack of eye contact can make you feel isolated and alone, a pair of eyes and a smile in the street can bring a sense of belonging.
