Why I Don't Get My Hair Cut on Tuesdays

i've been told for 20 plus years that you're not supposed to get your hair cut on tuesdays, ah, you know. And so i've never been able to find an explanation. How do we end up with these sort of narratives around faith that nobody has any explanations for? And the to how do we get into situations of extremism, where people become fanatical? I just believe this about human people, at some point someone made a decision. Beaue, the honest to god thought it was best,. like i don't buy the notion that just people just create systems, systems of control because they want to have their image and all kind of stuff. That's true
