* Every mode of travel has its signature mental aberration. Eskimo hunters traveling alone on still, glassy waters are sometimes stricken by “kayak angst”—delusions that their boat is flooding or that the front end is either sinking or rising up out of the water. Of related interest: “A Preliminary Report of Kayak-Angst Among the Eskimo of West Greenland” includes a discussion of Eskimo suicide motives and notes that four out of the fifty suicides investigated were elderly Eskimos who “took their lives as a direct result of uselessness due to old age.” No mention was made of whether they cast themselves adrift on ice floes, as you sometimes hear, and whether travel by ice floe has its own unique anxiety syndrome.
