When I was little, I always heard that if someone choked or coughed while eating, it was because food 'went down the wrong tube'. As a result, I believed that in peoples' mouths, just past where you could see in the mirror, were three different tubes leading to the stomach: the food tube, the drink tube, and the wrong tube. I even envisioned little plaques above the opening to each, labeling them so whatever I put in my mouth knew which tube to use.
A childhood belief about eating

others believed things like this
- if you eat toothpaste straight from the tube, you will get worms— wormelow
- I used to want hemmoriods so I could use a "float tube" in the tub and have a cushy toilet seat like my dad.— Tami
- We put food in our mouths, so naturally I believed my stomach was in my head.— Timb
- I always believed as a child your stomach was a big hand which squeezed your food out through your bum....— amc
- I was told when I was little that eating too much salt on your food would "dry up your blood".Anon
- I'm autistic, and I used to believe taking some of my sister's food while she was eating it was sharing.Anon
