I heard about this since I was a kid and always wondered if it was true.when I ask people they just say that without further explanation...is it true?
Ai ya. This isn't the first time this question has come up before, but...let's say It's Complicated. I commend to your attention the previous thread on the matter, with a top-level post from u/ThanklessAmputation and links to previous threads on the same matter. As always, should anyone have further information to add, please feel free to do so.
