Weird and Whacky Body Facts

Saturday, 7 March 2009

Did you know that your eyes always stay the same size as they were the day you were born? And that your nose is the same length as your thumb? What about the fact that your height is the same length as your arms stretched out, from fingertip to fingertip? And your foot is the same length as your forearm? Get out the measuring tape and check!

The human body is a fascinating place to live in. It can also be an icky one. If you were freeze-dried, for example, 10 percent of your body weight would be made up of parasites and other cling-ons like bacteria and mites! During your lifetime, you will produce enough saliva to fill two swimming pools. And how about your sweaty dad? He perspires enough sweat each day to fill six soft drink cans! And did you know that your stomach has to produce a thick of layer of mucus every two weeks – otherwise it would digest itself?

Here are some more weird and wonderful (and true!) facts about our bodies:

  • No one can sneeze with their eyes open.
  • When you sneeze, your heart stops.
  • Humans are the only animals to produce emotional tears.
  • Most people blink 25,000 times a day.
  • Coughing can make air move through your windpipe faster than the speed of sound.
  • The surface area of a human lung is equal to a tennis court.
  • It is impossible to lick your own elbow (but go ahead and try!).
  • Human thigh bones are stronger than concrete.
  • A caterpillar has more muscles than a human being.
  • The average person will accidentally eat about a pound of insects over their lifetime.
  • There are 60,000 miles of blood vessels in the human body.
  • Your nose continues to grow your whole life long (eat your heart out, Pinocchio!).
