5 unknown facts about human body

1How much you know about yourself? Well, you may be knowing much, but not THIS much! Here are some very funny yet rare facts about human body:

  • People generally read 25% slower from a computer screen compared to paper.
  • Bones in an adult account for 14% of the body’s total weight
  • Do you know the weight of an eyeball! The eyeball of a human weighs approximately 28 grams.
  • Now this is cool! The tongue is the strongest muscle in the human body. None of the diehard foodie reading these would deny it!
  • A human heart pumps enough blood to fill 100 swimming pools in an average lifetime. In the same time it will beat almost two billion times. Have you ever thought about it?
  • Have you ever asked yourself, why laughter is considered to be the best medicine? Here’s the answer! We exercise at least 40 muscles when we smile.
  • When you sleep, you grow by about 8mm (0.3in). The next day you shrink back to your former height. The reason is that your cartilaginous discs are all side typically with the finger like sponges by the force of gravity when you stand or sit. Now, don’t stand in front of your mirror posing asleep in the dead of night? You won’t be noticing the change!
  • The largest organ in the body is the skin. In an adult man it covers about 1.9m2 (20sq ft). The skin constantly flakes away – in a lifetime each person sheds around 18kg (40 lb) of skin.
  • A single human blood cell takes only 60 seconds to make a complete circuit of the body.
  • In 40 minutes, the average body gives off enough heat (combined) to bring a half gallon of water to boil.
