The ears are connected to the nose and throat through a channel called the Eustachian tube. This connection helps equalize pressure in the middle ear and allows for drainage of fluid. It also plays a role in maintaining balance and hearing function. 8
Wearing headphones for just one hour can boost the bacteria in your ears by up to 700 times. This rapid increase in bacteria highlights the importance of regularly cleaning your headphones to prevent potential ear infections. 9
Monte Pierce from the USA holds a remarkable record for stretching his earlobes. His left earlobe stretches to an impressive 12.7 cm (5 inches), while his right earlobe reaches 11.43 cm (4.5 inches). This extraordinary ability demonstrates the extent to which earlobes can be elongated. 10
