Thank you for your kind and rapid response. And I apologize if I too quickly took offense. Regards to you!
I don’t think they made them up. They just passed them down. It’s the “old wive’s tale” syndrome. Somebody thought it was true, probably in the age before the scientific method was a big thing, told their kids, who told their kids etc etc. A few of them, like the autism/ vaccine thing, are full on malfeasance but most are just teaching what they were taught without ever actually finding out if it was true. And some are just how people think, like celebrities dying in threes, once you “decide” to see the world that way then your brain sees it in those clusters.
