And speaking of scurvy, I am eternally amused by the thing where some ancient form of healing that was born in a time where people didn't know exactly how the human body works, or what causes it to stop working sometimes, that still somehow worked. Like how so many old folk medicinal plants were listed as a cure for various ailments that - from a modern view - are clearly just symptoms of scurvy, and the plant itself is rich in vitamin C.
I recall reading some story, no recollection of the exact time or place, where the king of a large empire suffered from constant horrible headaches and was incapable of falling asleep unless drugged or blackout drunk. Sick of taking temporary fixes to dull the pain and having to be sedated every night, he called up some old sage healer who was said to know how to fix things nobody else could explain, and the healer heard his symptoms and went
"Hmm. You spend too much time being a king. Your skull is packed so full of kingly thoughts that they don't all fit in there and that's why your head is in pain. You need to spend time not being a king." And prescribed him to schedule three days every month where he must go to a peasant village where nobody knows he's the king, live with a family there under a fake name and identity, work in the rice fields with them, eating the same food and sleeping on the same mats. Absolutely nobody is allowed to address him as the king, speak to him of any royal or political matters, and he himself is not allowed to think any kingly thoughts or think of himself as the king.
And naturally, this worked. Taking a regular scheduled break from a highly stressful office desk job to completely decompress, paired with physical exercise in the form of hard but simple physical labour, plain and simple food and Just Not Thinking About Your Fucking Job All The Time does help chronic stress, which here was worded as "spending too much time being a king clogs your brain."
Sometimes you do have ghosts in your blood, though I'm not entirely sure whether you should do cocaine about it.
