" It is therefore not going beyond what is fully granted by facts, to maintain that a general loss of interest in life, of the joie de vivre, the cutting of all the bonds of intense interest, which bind members of a human community to existence, will result in their giving up the desire to live altogether, and that therefore they will fall an easy prey to any disease, as well as fail to multiply. "

― Bronisław Malinowski , Argonauts of the Western Pacific
