My parents told me when I was little that the little bumps you get on your tongue that sorta hurt were called "lie bumps" so if I got one, it meant that I told a lie. I believed this up until I was in high school....kinda not really thinking about what I was actually believing. I still call them lie bumps when I get them.

I remember when I was young my grandmother said don't turn the water on to hot or I would scaled myself. I thought by this that it would be so hot my skin would melt off and there would be nothing left but bones
I used to have weird ideas about anatomy. I used to think mums corns on her feet were actually pieces of sweetcorn she had eaten and they had travelled to her toes and got stuck. I also used to think that your bladder and bowel were a small ladder and desert bowl floating around in your tummy, I always imagined the bowl as pretty fine china. Finally I though that when I bled from a cut I was draining from the head down and by the time I was 10 by brain would be dry.
When I was 8 my grandmother told me that dying your hair would give you cancer. I believed this until I was 12.

I used to believe that because I had no birthmarks on my body, I was a robot. I would sit there looking and looking for birthmarks, and then cry when I couldn't find any because I didn't want to be a robot.
I used to think that my body was hallow and tiny people were living in it.
When I was little, my mother told us that ear wax was duck poop. Every time she cleaned mine and my brothers' ears, she would quack. Whoever had the most "duck poop" got the loudest quack. We were always competeing and trying to make more duck poop in our ears.
I used to think that if someone poked my belly button, it would open up. I would freak out when someone would poke my belly button. I have my mom to blame.

When I was younger my mum told me that cavities in your teeth are caused by small worms burrowing and living in the tooth! I believed this till I was about 12!
I remember when I was 5, I had lost my first tooth. So, as a very curious child would, I asked my mother what the tooth fairy does with the teeth she takes. "i dont know!" A few weeks later, I was watching t.v, and an old man's dentures fell out. I asked my mom why his teeth fell out, and she said they were fake teeth made by a company for old people. I asked what they were made out of, and she said she didn't know.... So, naturally, I thought that's what the tooth fairy did with all the teeth[she made dentures!!!]

I used to believe that if you kept your eyes open for too long, they would fall out. I spent most of third grade squinting.
When I was younger i used to rip my split ends apart. To get me to stop my dad told me that if I ripped up to the hair folical it would cause an infection and the infection would grow to my brain and kill me. I believed it until I was 15 and I saw someone doing it so I told them that and they laughed at me.
my sister told me once when catching me playing with my belly button that if i poked it too much i would turn inside out. I was so scared i started crying thinking that i might of done it too much already when i asked her about this she just said "all we can do is wait and see" i was absolutely terrified that i was going to die and to this day i dont like touching my belly button, im 22.
When I was about 13, I had heard that an original champagne glass was modelled on Marie Antoinette's breast. I was familiar with the long thin champagne flutes to be the original champagne glasses and it wasn't until I was the age of about 18 that I realised the original champagne glasses were wider and shallower. For all that time I thought that Marie Antoinette had really long thin boobs!
I used to believe that everybody used to have a tail that grew out of your tailbone, but you got it cut off at birth. Same with shoulder blades-- or, as my mother called them, wing-buds.
When my mom was pregnant with my sister (I was about 3 1/2 or 4) I noticed that her normally innie belly button got flatter and more shallow as her belly grew. I assumed this was the purpose of a belly button- it was just twisted up extra skin that would unfurl to make room when the woman's belly grew when she was pregnant. I assumed men had them for the same reason they had nipples- decoration.
When I was younger I saw my mom doing laundry and when she pulled out a bra I asked her what it was. She told me it was a 'boobie hanger' So for the longest time I thought that was actually what it was called. Needless to say I was embarrassed when it came time to get a bra :D
