Fighting loneliness

The authorities of a Swedish city have called on residents to greet strangers in order to combat loneliness. According to research, nearly half of young people aged 16 to 29 in Luleå have experienced problems related to loneliness, which are further exacerbated by the habit of keeping distance. The new campaign aims to change this situation. The concept is simple: just warmly greet peers on the street with the word 'hej' - a common Swedish greeting.
