Neulich hatte ich einen Auszug über's Furzen aus Robert Provines Buch Curious Behavior gebloggt, heute hat der Guardian einen weiteren Text daraus, diesmal geht's um die Psychologie von Hahahas und Hihihis und Lach-Epidemien. Klingt wie ein Buch, das ich lesen muss:
Consider the bizarre events of the 1962 outbreak of contagious laughter in Tanganyika (now Tanzania). What began as an isolated fit of laughter in a group of 12-to 18-year-old schoolgirls rapidly rose to epidemic proportions. Contagious laughter propagated from one individual to the next, eventually infecting adjacent communities. Like an influenza outbreak, the laughter epidemic was so severe that it required the closing of at least 14 schools and afflicted about 1,000 people. Fluctuating in intensity, it lasted for around two and a half years. A psychogenic, hysterical origin of the epidemic was established after excluding alternatives such as toxic reaction and encephalitis.
