### Transcript

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 the tongue is covered in about 8.000 taste-buds, each containing up to 100 cells helping you taste your food. Every 7 years your cells are dying and being replaced all the time.

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.

Submitted by Caspiterin89 on Mon, 08/03/2020 - 14:56

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!

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.

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.

Submitted by user on Tue, 03/24/2020 - 17:04

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.

Did you know your body is 75 percent water, and also, your brain is 80 percent water. Thats why if you don't drink anything in 3 days, you may die.

Submitted by nadia0 on Wed, 08/21/2019 - 20:46

Do you know any amazing facts about the human body? Yes I do. For example, did you know that you can may die if you do not drink water for 3 days, buy you'll survive if you do not eat for 3 days. It happens because our body is 75 percent of water, so, we need water to survive before food.

Hi ali,

Have you tried right clicking on the word 'download'? I've just checked it and it works fine for me, so I think the problem must be a local one on your computer.

Can you try on another computer or device, or try a different browser? You can also try to 'clear the cache' on your browser then try again.

I hope that helps!

Best wishes,
