Head
With all the dangers attending any protracted, unplanned stay in Antarctica,
keeping your head can be one of the biggest challenges of all. According to
Survival in Antarctica, "Survival records have shown that two things are
of paramount importance to survival: the determination to live (a positive
mental attitude), and the alleviation of fear." In the perpetual darkness of
the Antarctic night, both can be devilishly difficult to achieve, much less
maintain, and a number of scientists who have overwintered in Antarctica have
suffered mental problems.
