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!

Spesking of bananas, I've heard that bananas and gingers are the same kind!
(ﾉ*'ω'*)ﾉ彡┻━┻
I saw photos about mites and it is icky !
euughhh I google it, you're right
Obviously, bananas are different from human bodies. What about the similarity ? 50% of human DNA is the same as a banana.
Wow… Bananas and human have the same root?
I've got some classmates who have allergy to bananas, on the other hand, I like banana. Might this show that my DNA need more banana cells?? Anyway, I think 90% of Mr.Hormer's DNA is the same as a banana! !
(≧ڡ≦*)
I was impressed by the fact that most of the atoms are only empty space ,just air or nothinges and if it took it out our body would be very small. This way we are empty. It is rediculous.
I am very surprised because I did not know that there were so many body cells. Did you know that a nap of 20 minutes is good for our health. In fact, we help to improve our concentration, mood and productivity.
Hey ivantorre! I know that 20min. nap (particularly in the afternoon) is good for our health!
Did you know how long a person's DNA is when it is stretched?
It's 2.5million time around the earth!! A great mystery in our body!!
In my case I find it very interesting that something like bacteria are so useful and necessary to live and that most of the cells are atoms empty , air or nothing. Another interesting factor is that when you look at someone you love, your pupils dilate and when you look at someone you hate,occur the same. Also, an interesting fact is that foot thumbs have two bones
, while others have three bones.
Wow, interesting! In that sense, nobody tells if sb loves me or hates me by judging their eyes?! I always tend to think the former, cause I'm a kind of optimist!

Hi Aitorze. I didn't know that about the big toe (that it only has two bones). That is interesting. Thanks for sharing :)

We need sleep at least eight hours to stay good all day until when you go to bed next day. We have 7 octillian cells in our bodys.
We have 7 octillion atoms in our bodies !
The tongue are consists from sixteen muscle individual.
a cell blood it takes sixty second in tour all the body human.
the tongue are consists from sixteen muscle individual
I know that hair grows us half a millimeter a day.
A cell blood it takes sixty second in tour all the body human.
I know , the Freckles are caused by uneven production of melanin .
I know some things about the human body, for example that 75% of our body weight is water or that people are morning 1cm higher than in the evenings.
I know it, too. In the evenings we are smaller than in the morning because the gravity power crumples up us. I think that science, specially biology, is amazing!
I know some interesting facts about the human body. For example, if we join all the blood vessels in our body, it would measure about 97,000 km.
Wow, it's longer than making the double circuit of the equator!!
Oh, I feel the universe in my body!!
ヽ(´ｰ`)ﾉ
I know another amazing fact: Our thumb is so long as our nose.
All amazing facts I knew about human body are already listed in comments.
I know one amazing fact : A woman's ovaries contain nearly half a million ovules, but only 400 have the opportunity to create a new life.
i knew that when we see the person that we loved, our stomach feels butterflies.
Oh, I knew it! Not so amazing, actually…!

Did you know that blood travels through the whole body and come back to the heart with only a heart pump. In addition, you need to breath by your nasal to enter a clean air to your body. Also, the small intestine is 5 metres long if it is straight, but because it takes a loopy shape in our body it looks much smaller than that.
Something amazing the human body, some people can do forms with language and those people they know how to do if your parents know it.
