The Human Body – Unusual Facts

I found the article 16 Unusual Facts About the Human Body quite interesting…

  1. Did you know that our tongue has its own unique print, like a fingerprint?
  2. This one is kinda gross… “Humans shed about 600,000 particles of skin every hour”…we lose about “105 pounds of skin by age 70.
  3. As we grow our bones fuse together, so “an adult has fewer bones than a baby.”
  4. Ok, another gross one…we “get a new stomach lining every three to four days”…this is so the acids our stomach uses to digest food don’t digest our stomach.
  5. Our noses can remember 50,000 different scents…no wonder that smell of a perfume or a certain food takes us back to a specific day, place, or person…
  6. Our small intestine is about 18 – 23 feet long, hence the need for it to be looped back and forth upon itself.
  7. “This will really make your skin crawl: Every square inch of skin on the human body has about 32 million bacteria on it, but fortunately, the vast majority of them are harmless.”
  8. The reason some people have smelly feet is because of sweat. “A pair of feet have 500,000 sweat glands and can produce more than a pint of sweat a day”…gross!
  9. “­The air from a human sneeze can travel at speeds of 100 miles per hour or more”. PLEASE cover your mouth and nose while sneezing!
  10. “Our heart pumps about 2,000 gallons of blood” every day and there “are about 60,000 miles of blood vessels in the human body.”
  11.  “The average person produces about 25,000 quarts of saliva in a lifetime…enough to fill 2 swimming pools!
  12. “By 60 years of age, 60-percent of men and 40-percent of women will snore” and “can reach more than 80 decibels”…which “is as loud as the sound of a pneumatic drill breaking up concrete”.
  13. “The average human head has 100,000 hair follicles, each of which is capable of producing 20 individual hairs during a person’s lifetime”.
  14. Fingernails grow faster than toenails, and fingernails on your dominant hand grow faster than those on your other hand.
  15. “­No wonder babies have such a hard time holding up their heads: The human head is one-quarter of our total length at birth but only one-eighth of our total length by the time we reach adulthood.”
  16. A person can go up to 11 days without sleep…after that, it gets deadly…
