• • The main reason for our noses is to smell things, and we can smell a lot of them. In fact, the nose can remember up to 50,000 scents.
  • The femur is as hard as concrete, sometimes harder. It takes over 4,000 newtons to break.
  • You have no sense of smell when you are truly sleeping.
  • Like fingerprints, each tongue is different. So could they track criminals down with their tongues?
  • The sound you hear when you crack your knuckles is actually the sound of nitrogen gas bubbles bursting.
  • The smallest bones in the human body are the ones in the ears. It is only about 1/26 of an inch long.
  • There are 100,000 miles of blood vessels in an adult human body.
  • It would take 8 pounds of pressure to break your jawbone. Those Jawbreakers don’t stand a chance against your jaws of steel.
  • Bananas and humans share about half of the same DNA. Wait, does that mean humans are half banana or bananas are half human?
  • The average human body contains 0.2 milligrams of gold. Wow, humans are worth a lot.
  • In order to live, you have to have blood in your body. One way we get this is through the heart. The heart pumps 2000 gallons of blood each day.
