I’ve been looking into feng shui lately, specifically the concepts about what makes a person feel more safe or at ease in a space, such as relaxing or sleeping facing the entrance / exit.
While reading, I came across the guidance that you should always shut your toilet seat to prevent your good fortune from being flushed. The real reason you should keep it shut is so it can’t mist shit-water all over your toothbrush every time you flush. Also so your pets don’t drink out of it.
What other things did humans throughout history accidentally get right?
Bloodletting actually has its uses. It’s rare, but a valid treatment. It’s called phlebotomy now, but it’s essentially the same thing.
I don’t remember exactly what the condition was, but I remember my grandfather went through it. Something to do with too much iron.
EDIT:
According to chatgpt, the condition is called hemochromatosis. It matches my grandfather’s description of having high levels of ferritin.
