I just had a flashback to our family friend who used to always say that a woman who was on her period couldn't hold a baby boy because it would somehow hurt their penis. I have never heard of such a thing since and obviously it's not true, but they really believed it! I remember her daughter who was my age picking up her nephew and her mom yelling at her to put him down because she was on her period and she was like 'oh yeah I forgot.' wtf?
Anyway, what are some "old wives tales" that you've heard of that are a bit off the wall. Anything that crazy?
