SCURVY: Horrific as It Was Deadly for Sailors. “Scurvy starts with lethargy before causing achy joints, swollen limbs, and loose teeth, according to Real Clear Science. From there, sufferers get swollen gums, bad breath, and bruising. The skin turns yellow, then black, just before sufferers die from internal hemorrhaging. The tragic part is scurvy is ridiculously easy to cure.”

I wonder what present-day diseases will be similarly regarded in a hundred years.
