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?
Same goes for shellfish - unrefridgeated it can go nasty quickly, and if you live in a hot environment that’s gonna be even faster.
I grew up on the coast, and my parents always had this rule to never eat/cook/serve shellfish that weren’t fished (shellfished?) same day or yesterday.
