What stupid beliefs did yo have as a child that turnt out to be false?
For example: When I was a kid, I believed that whether you got an innie or outie bellybutton was your doctors choice. I thought that Your bellybutton was stitched up right after the cutting of the umbilical cord, and was essentially just the result of how the doctors chose to stitch you up that day.
Obviously not true, but honestly was very logical thinking.
