In China, a man had the uncomfortable sensation of something crawling around inside his nose…and bad breath that came directly from it. One night, the unnamed 58-year-old man woke up feeling the sensation in his nostril…which turned out to be a cockroach that crawled into his nasal passage while he was asleep. Eventually, it crawled down his throat, and the man couldn’t cough it out…but was able to finally go back to sleep. The next day, he was able to recall the whole incident…and also noticed that his breath was exceptionally bad. It was when he started coughing up yellow gunk that he finally decided that medical attention was in order. An ENT specialist was finally able to locate the now-dead cockroach and remove it from his trachea. The man has since made a full recovery and his breath smells much better now.
