A: Hey, I’m reading this really interesting article about the human body.
B: Yeah? Well, we know all about that from biology lessons.
A: No, we didn’t learn much at all at school! They’re discovering loads more things all the time. Really amazing things! Did you know that only about one tenth of the cells in your body are really you? The rest are bacteria.
B: What? I’m not really me?
A: No, of course you are you, but you also have millions, or trillions, of bacteria in you.
B: Eeeeuuugh!
A: No, they’re mostly really helpful. Someone did an experiment to see if animals can live without bacteria, and he found that a lot of them died or had to have a special diet. Animals need bacteria to digest food, you see. So we’re better off with bacteria.
B: Unless the bacteria are bad.
A: Unless they are bad, but they’re nearly all good. Oh yeah, and going back to cells, do you know how many cells you have in your body?
B: Quite a lot, I’d say. A good few.
A: Yeah, but how many?
B: I don’t know. I’m not mathematical.
A: 7 octillion! That’s 7 plus 27 noughts.
B: I knew it was a lot.
A: OK, that’s an amazingly huge number, almost impossible to imagine. But the really weird thing is that most of the atoms are empty space, just air or nothingness. And if you took out the empty space, you could fit your body inside a tiny cube which measures one 500th of a centimetre on either side. That’s a box measuring 0.002 of a centimetre on each side. You’d be much too small to see.
B: Mmm, I can imagine that. It sounds like something that would happen in a really bad Hollywood movie. You know, a mad scientist goes: (funny voice) ‘I’m going to extract all the air from your body’. OK, enough facts for one day.
A: Don’t go! One last thing, did you know …
B: No.
A: Did you know that you probably have mites in your eyelashes?
B: Mites in my eyelashes? What are mites exactly anyway?
A: Yeah, they’re very small creatures, like insects, only not insects. They’re about a third of a millimetre long, so you can’t really see them. These particular mites live in eyelashes and eyebrows.
B: But in mine?
A: Well, maybe not. Only about 50% of people have them, and more older people. So you might not have any. Anyway, they’re completely harmless, they just eat dead skin.
B: Yeah, right, harmless. I really would have preferred not to know that.
A: Sorry.
B: I mean, really!

I know that we have almost the same number of hairs that a chimpanzee
I am very surprised about the fact that the evolution of the use of our hands because they were other feet. However, we were able to walk on two legs and now we use our hands for catching objects and writing, the most important activities for the humanity. CR7 BALON DE ORO.
Hi. Do you know the English name for that? It's called the Golden Ball. But because it's a French award, we also use the name in French (Ballon d'Or).

The eyes receive approximately 90 percent of all information processed by the brain, making us basically visual creatures.
I think the human body have a lot of amazing facts.I know that we can survive two days without water , and seven without food. Also, I remember that human bones are stronger than granito. Finally , women take longer to Burn Fat than men.
I know a bit amazing fact about human's body.
The brain consumes the amount of power as a 10-watt light bulb and nerve signals to and from the brain can travel 273 km a hour.
Our heart is incredible, it pumps about 7570 litres of blood through our bodies everyday. Although the heart has almost nothing to do with feelings, it is said to be the symbol of love.:)
Hi giang!
Amazing, you're like a walking library!
Science, Music, Literature, South East Asia…..
Hmm... insightful!
No no, I am not excellent as you thought. I only know a bit about fields. Our knowledge is just a raindrop of a ocean and just a star of the universe.
Elsa007 is like a librarian who has the key to the library.:D
Ha ha ha ha…
as was expected, I like your wit, giang! ☆
I know that when you are sleeping and you wake up in a fright is because your brain think that you're dying
I know the fact that we exercise at least 36 muscles when we smile. keep smiling :)
I know that the length of the both hands from shoulders to the fingers equal the same length of the body ,Except the basketball players
Totally agree, our Physic textbook mentioned this.
I don't know anything about amazing facts.
Our fist are same size with our heart. Since we were born until we die, Our eyes's size always the same and the last thing is we can't lick our elbow.
I know how long is your thumb finger is exactly the same size of your nose. Have you try to proof it? I did and it worked for me.
I know not all of us see the same colours. And I'm not talking about any disease. Even if the colour is "red" or "green" or anything, you could not see exactly the same colour that I'm seeing. I guess that's the reason some people like some colours that others just don't. I love blue and green.
I know the left hand nails grow slower than the right hand nails, that's because most of the times you use the right hand. Unless you're left-handed, then you use more your left hand so your nails in this hand will grow faster than the other.
I know pubic hair, eyebrow hair and eyelashes hair stops growing at a time, it's not the same thing with the hair in our heads: it just doesn't stop never. (Probably you notice this yet, but I wanted to tell anyway)
I know other things, but I don't know how to say them in english, haha. It will be next time. :) Sorry, hope you enjoy it.
Hi Ofelia,
Wow... Interesting! Soon I examined the length of my thumb and nose, but my thumb is slightly longer anyhow. The result wasn't possibly the same...
But I agree with you about the color. Actually there're many variations in 'blue', 'green' 'purple' etc... so only I can say; I love bluish, for example. Also the combinations of the colors will change the impression of the color you see!
I haven't thought about the fact of nails! But it's understandable as well as hair! They share a common habit that they grow for protection and supplement, depending on DNA...
Well, views in this light, we're never be alone but always with these amazing millions of cells! ツ
Looking forward to hearing your other facts about the body! Thanks for sharing!
Hi Ofelia,
Wow! You know a lot of facts about the human body. I just tested your theory about the thumb and the nose being the same length and I think you're right! It worked for me!

If you stretched out the 300,000,000 capillaries in your lungs end to end, the line would extend from Seattle to San Diego, or about 1,300 miles
The human brain can read up to 1,000 words per minute.
Human fingers are so sensitive, that if your fingers were the size of Earth, you could feel the difference between a house and a car.
I know that when you do something nice , in your brain creates endorphins ( hormone), and also is creating serotonin and dopamine( these hormones addictive). For example when you do sport , in your brain it is creating endorphins.
You know very well, Komorniki! Aha momentツ! Although I've heard that 'nice' can be interpreted differently in individuals. For instance, what a serial killer feels nice would be different from ordinary people....... aiiieee!!
if on how important white blood cells in living organisms
Have you heard about 'Glabella'! It is the space between your eyebrows!
Another interesting word 'Borborygmi' - it is the noise or sound which our stomach makes when we are hungry!
I know that you have no sense of smell when you're sleeping!
I know one amazing fact: When you blush, your stomach turns red, too.
