When I was about 5 years old, I had chewing gum for the first time, and I was told I couldn't swallow it. However, I ended up swallowing it anyway, and concluded that I was the only person who could swallow gum and that I was smarter than everyone else, because they couldn't swallow gum.
A couple of years later, my brother told me that if you swallow chewing gum, it stayed in your stomach for seven years, and I believed him. I was then terrified of swallowing gum, and I counted how many years it would take before the gum I'd previously swallowed would come out...
