You'd think if you had inhaled a pen cap as a kid, that memory would stick with you. Not for a man in China, who is only identified by his surname Wang. In case you missed it, Mr. Wang went to the hospital after he began coughing up blood. It was then doctors discovered, and Wang remembered, he has had a pen cap lodged in his lung for the last 20 years.
Surgeons were able to remove the half-dissolved pen cap, which it turns out had caused Wang medical issues his whole life. He says despite having lung infections and a chronic cough, he hadn't connected the dots.
