An article on scurvy opens up with the story of the Norwegian whaling station named Smeerenburg, which was abandoned every winter during the off season. When someone got the great idea to leave seven men there all winter to guard equipment, they all died by the end of February.
Scurvy is a particularly horrible way to die, as lack of vitamin C prevents the body from producing sufficient collagen. The symptoms include pain, bleeding, and the inability to move correctly as the body falls apart at the seams. Couple these awful symptoms with the fact that no one knew why it happened, and many societies did not know how to cure it, until James Lind experimented with folk remedies in 1747, including citrus fruits. Even that did not help much, as it took decades for authorities to implement Lind's recommendations.
