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!

Did you know that if you were to uncoil all your DNA it would be able to stretch from Earth to the Sun and back 61 times!
Many of the data that were mentioned I didn’t know, everything that is inside our body is impressive
I do not know many curious facts about the human body but some of the ones I know are:
- the largest bone in the body is the femur
- most of the bones are in the feet
- the skin is the largest external organ of the body
- About 32 million bacteria live in every centimeter of skin
I don't know I wanna comment ¯\_(ツ)_/¯
I found all the conversation very interesting, specially de cells part, because I had never thought about all the things that compose my body, and how small they are.
Before that I didn´t knowed much interesting facts about the body.
I know that a newborn baby has about 300 bones, but an adult human has 206 bones because some bones grow together.
I didn't know that it's amazing
Interesting lesson...
My fun fact:
Your body produces 25 milion cells every second. And thats a lot.
It’s really interesting but when I heard about mites I was like: ,,Ewww” I know that it’s a normal thing but know that something lives in your eyelashes and eyebrows is just... weird? I don’t know but I rather won’t think about that too much.
I know that bone is stronger than steel.
Lol, your avatar make me laugh XD
I knew about mites in human's body from one TV programm. I was really surprised when I knew it, but that fact didn't make me beeing scared.
I didn't know any of these things but I know that infants are born with approximately 300 bones, but as they grow some of these bones fuse together and by the time they reach adulthood, they only have 206 bones.
i knew about the mites in the eyeslashes, and that bacterias are useful for digest food
I am really like,“ I really would have preferred not to know that." Amazing fact learning.
very interesting lesson :)
I didn't khow the amazing fact too
Honestly, the human body is one seriously complex and mysterious mechanism that sometimes confuses even the most qualified specialists.
I knew an interesting fact about our body that deeply impressed me. You have two kidneys, but you can live without one of your kidneys. Some people are born with only one because the other one did not grow properly, or was damaged, and they can live long happy lives. This is an amazing thing.
The facts were really curious! Another shocking fact about our body is that with all the iron that we have in our body we could make a nail long 7 cm!
Amazing Facts About Our Body
1.Smile 17, frown 43 running muscle, so smile is much easier!
2.The energy produced by our brain can burn a 10 watt bulb.
3.The total length of the veins in our body is 96.500 kilometers!
I really like biology so listening this courses helps me know another things. then thanks to British council to share with us this audio. I know another fact like, there is bacteria in the human body that can help also human digest food they called them enzymes without them we can't digest the food.
People sometimes think that they don't use most of their brain cells but it's not true. We use 100 percent of our brain cells. But everybody can't grasp or process everything. Thus the difference between fools and intelligents.
Unfortunately, I'm not interested in Biology but I start loving it by listening to these beautiful facts about our body
Interesting! How many things we learn practising our English skills!
one incredible fact is that our heart strat to work when we are 2 monts old
I don't know if someone commented this, but the fact is: if you stretch all DNA of your cells and put it together as one string, that length would be twice the diameter of the solar system
These are really interesting facts about human body. Unfortunately, I do not know any facts.
I found it interesting where an experiment was done and he says that animals do not survive without bacteria unless they are subjected to a special diet. I think it is impossible to try to identify them with the naked eye.
Interesting facts about micro size of human body. And I can add this, the vaccine is injecting some bacteria to our body to gain immunity against bacteria. So in a possible infection, body can identify the bacteria and beats them.
