Incredible Facts About the Human Body

I came across these the other day, not sure on the source, but enjoy them anyway.


Very interesting facts about the human body you probably didn’t know.

1. The stomach’s digestive acids are strong enough to dissolve zinc. Fortunately for us, the cells in the stomach lining renew so quickly that the acids don’t have time to dissolve it.

2. The lungs contain over 300,000 million capillaries (tiny blood vessels). If they were laid end to end, they would stretch 2400km (1500 miles).

3. A mans testicles manufacture 10 million new sperm cells each day – enough that he could repopulate the entire planet in only 6 months!

4. Human bone is as strong as granite in supporting weight. A block of bone the size of a matchbox can support 9 tonnes – that is four times as much as concrete can support.

5. Each finger and toenail takes six months to grow from base to tip.

6. 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 48kg (105 lb) of skin.

7. When you sleep, you grow by about 8mm (0.3in). Through out the next day you shrink back to your former height. The reason is that your cartilage discs are squeezed like sponges by the force of gravity when you stand or sit.

8. The average person in the West eats 50 tons of food and drinks 50,000 liters (11,000 gallons) of liquid during his life.

9. Each kidney contains 1 million individual filters. They filter an average of around 1.3 liters (2.2 pints) of blood per minute, and expel up to 1.4 liters (2.5 pints) a day of urine.

10. The focusing muscles of the eyes move around 100,000 times a day. To give your leg muscles the same workout, you would need to walk 80km (50 miles) every day.

11. In 30 minutes, the average body gives off enough heat (combined) to bring a half gallon of water to boil.

12. A single human blood cell takes only 60 seconds to make a complete circuit of the body.
13. The eyes receive approximately 90 percent of all our information, making us basically visual creatures.

14. The female ovaries contain nearly half-a-million egg cells, yet only 400 or so will ever get the opportunity to create a new life.

15. The purpose of eyebrows is to keep sweat from running into the eyes.

16. The number one cause of blindness in America is diabetes.

17. You blink over 6,000,000 times per year.
18. The average man spends around 5 months of his life shaving.

19. Hair is the second fastest growing tissue on the body. Bone marrow is the first.
20. Hair is made out of the same substance as fingernails.

21. Around 20% of the oxygen you breathe goes to your brain.
22. You cannot properly tickle yourself as your brain knows that you are touching yourself and will not react in the same way as if something foreign were touching you.

23. In one day, you shed about 10 billion skin flakes.
24. A human salivates an average of 1-3 pints of saliva every day.
25. An adult human body requires around 90 pounds of oxygen per day.

26. The heart produces enough pressure that it can squirt blood at a distance of over 35 feet.
27. The human heart beats an average of 35,000,000 times per year – thus, the average human heart beats around 100,000 times per day.

Upper Cervical Care is about allowing all of these amazing things to happen without interference due to head neck misalignment.

How To Misalign Your Head And Neck...Let Me Count The Ways

(Editor's Note:  Fifty to be exact and this is far from a complete list but it gets you thinking about why it is important to be checked periodically.)

by Dr. Deborah Sesker

In a perfect world, none of us would have been born by forceps, or by Cesarean, or with the doctor pulling with too much force on our heads.

In a perfect world, none of us would have fallen off the side of the bed when we were two, tripped down the stairs at age eight, or rolled our car in the ditch at eighteen.

But these things happen. And when they do they often stress the muscles and ligaments of the upper neck to the point where the bones misalign and lock-down, placing stress on the spinal column and the delicate nervous system inside.

If we were lucky enough to have our parents take us to an upper cervical doctor at a young age, we might have only lived with our neck misalignment for days, weeks, or maybe a few years before having it properly corrected.

But most of us aren’t, which means many of us live one, two, or six decades before we ever have our atlas unlocked by our upper cervical doctor. By this time ligaments are tightened, muscles have developed amnesia, and we have patterns of movements which place stress on the top of our spine without us even knowing.

All of this is to say, that even a really good upper cervical correction may not hold very well, especially in the beginning of our care. And if we want to make the most of our upper cervical  care, we’re going to need to be careful what we do on a day to day basis.  Here are 50 simple ways you could lose your upper cervical alignment.

    Sleeping on your stomach.

    Sleeping on your side without proper neck support.

    Reading in bed with a book on your chest.

    Watching television in bed with your chin on your chest.

    Falling asleep on the arm of the couch.

    Falling asleep upright in a chair.

    Falling asleep upright in a chair and waking up with an ear resting on one shoulder.

    Falling asleep anywhere other than your bed.

    Propping your head up on your hands, fist or palm under your jaw, for more than a few seconds at a time.

    Looking up for more than a minute at a a time, be it stargazing, birdwatching, or painting a ceiling.

    Stretching your neck by pushing it forward, backward, or pulling it to the the side with your hands.

    Having anyone else push or pull your head to stretch your neck.

    Turning your head without moving your shoulder to look behind you while driving.

    Driving and hitting anything going more than five miles per hour.

    Driving and getting hit by anyone else going more than five miles per hour, for that matter.

    Getting into your small sedan by craning your neck to one side to sit down over and over again, instead of sitting down facing outward, and then rotating your body inward.

    Getting into a pillow fight.

    Getting placed in a head-lock

    Getting up, turning over, or moving your body by leading with the head and neck, and not with the pelvis.

Does doing any one of these 50 things mean you’re going to need another adjustment? Not necessarily. Everyone is a little bit different. (Some kids have played high school football without losing their alignment.)

But they are common ways that you can set your upper cervical care backwards, and they’re worth considering if you’re having a hard time holding your alignment.
