Friday Fun: Five Gross and Goofy Body Facts

  • According to the Guinness Book of World Records, Monte Pierce can stretch his earlobes to a length of nearly 5 inches (13 centimeters). Using them like a slingshot, he can launch coins up to 10 feet (3 meters).
  • Know anyone with wrinkly lines on their earlobes? Some scientists say they’re a sign of heart disease. Nobody knows what causes the curious creases. They might form when blood vessels in a person’s earlobes collapse.

  • Most parts of your body will stop growing by the time you graduate from high school, but your ears never stop. Between the ages of twenty and seventy, a person’s pinnas grow about 0.5 inches (1.3 cm).

  • You know that soft, swishing noise you hear when you hold a spiral seashell up to your ear? Some people say it’s the sound of crashing ocean waves. But that’s not really true. What you’re hearing is sound waves bouncing around inside the shell.

  • If your ancestors came from Europe or Africa, your earwax probably forms soft, sticky, yellow clumps. But if your ancestors were Asian or Native American, your earwax probably forms hard, crusty, gray flakes.
