regarding the query about the ridges under one’s nose,
I spent quite a while like an idiot trying to find the replies to this before realising there weren’t any, here’s one now though.
in Hewbrew grade school we were told when babies are in the womb an angel pops in there to say hi and teach you the entire Torah (old testament to you goyim), apparently you memorise it with the angel’s help. shortly before birth the angel touches your face, right below your nose causing the indentation discussed in the post linked to above, and simultaneously in a rather cruel joke I suppose causing you to forget the Torah you had just been taught. what is the point of this -I have no idea, I wonder if anyone else who attended hebrew school ever heard this story?
they told us a lot of other bizzare things as well but that one sticks in my memory.
