I remember when I was a young teenager, about 13 or 14, an Aunt told me not to get wet when it was that time of the month because it could produce seizures! Yuck! No showers! No way!
Oh, my best friend in high school, her mother told me it was a good thing that she gave coffee to her boys when they were little so it could stunt their growth. All of her boys were at least 6'5"! She said can you imagine how tall they would be if she hadn't given them coffee!
