When I was a child I believed cavities were things that happened around the time that my mother was a child, and no child had cavities in modern times. This happened because people back then didn't know how to brush their teeth, and in modern times everyone was smarter. I believed it until I was 15, and had my first cavity. I felt really bad and asked the dentist if he did fillings in young people.

I used to believe there was nothing inside our bodies when I was about 4.

My parents had a beach house, so I was well familiar with sea weed. I wondered what was inside of people. I was intimately familiar with blood--so I imagined that people were filled (like the Scarecrow of Oz) with bloody seaweed. This was well before I met the "Oz" stories.

I was told that, when something was stinking real bad, the stench would get in my mouth if I opened it... I almost threw up at the thought !
To this day I keep my mouth shut when I smell something disgusting.

When I was a kid, my grandfather always used to ask me where I got my nasty brown eyes from... So I thought that having brown eyes was something ugly and bad... I think I must have been in my teens when I realized that my grandfather had brown eyes himself, and was actually proud of the fact that I had brown eyes...

I had a bruise on my leg when I was about four, and I thought my leg was going to get black, rot, and fall off...just like bananas do

I used to believe my thoughts came from my tummy.

When our science teacher told us that our heart pumps blood to every part of our body, I used to think it's amazing that at the sound of the "thump", blood rush out from the heart to every vein and vessels, and each drain of those blood rushes back to the heart at the end of the "thump". I must have had a powerful heart!

My Dad always told me that when you lost a tooth, if you did'nt stick your tongue in the hole, a GOLD tooth would grow in instead of a regular one. Never could keep my tongue out of there though.

my dad used to pretend to pull my nose off and hold his thumb between his index and middle finger. I believed he had and would scream, "give me it back!" which he kindly did.

My brother once said to my mom, "I know the difference between boys and girls...boys heads are round and girls heads are funny shaped." He thought that because my moms hair was puffy and made her head look like a different shape if you were sitting in the backseat behind her and didnt know better.

I used to think that girls' anuses were green. I remember thinking that as late as high school.

I used to believe that if I didn't clean my ears that carrots would grow inside.

I snuck downstairs early one morning to throw away my mom's donar card because I thought that they just came for you at any time when they needed your organs

i used to believe that you only had as much blood as was in your body and if you got a cut that bled you had to save that blood somehow or you would run out...the other kids thought it was pretty gross that i sucked my own cuts.

when I was a child, I used to believe that if someone accidentally broke a body part such as an arm or leg etc, you could go to the store and purchase a new one.

When I was little I somehow was under the impression that the word "balls" meant butt. One day in school I fell on my butt and I screamed out real loud "MY BALLS HURT!". I was real young, so only the teacher laughed.

After watching blue peter it showed a diagram of a person's circulatory system. Half the blood was red and the other hal was blue.
For years, possibly until i was about 13, I believed that some of our blood was blue and couldn't understand why I'd never seen my blue blood before
