Things that are actually pretty weird when you think about them?

OOH!

Also, time zones.

Logically I get it, but when I speak to my colleague in my morning time, her afternoon (she's 7 hours ahead of me) I always want to ask her what that day's been like so I know what to prepare for

I often wonder if I've ever drank the same water molecule twice...

And the thought that solid objects are actually made up of empty space (ie the spaces between the atoms that make up the materials)

And that we're all stuck to this blob of rock flying around the solar system at 67,000mph, and that blob of rock itself is then spinning at 1,000mph.

Things like this are the reason I don't sleep well!

Commerce and industry- all us humans , who are just a bunch of cells , sitting in concrete boxes , fiddling about with paper and files and systems, getting all het up if a mistake is made , it’s just so weird . Why can’t we just concentrate on surviving? I’d like to go back and live as a cave woman and worry about the basics.

Life in general, it fascinates me.. people just going about everyday lives, the ups and downs, on this tiny planet in this huge empty expanse.. its so weird

Similar to the sleeping thing when everyone lies down in the dark at the same time, I always think that on Christmas Day how strange it is that most people are doing exactly the same thing and eating the exact same food up and down the country!

But also 'technology' im typing this on a 'phone screen' and immediate, all of you, all around the world can read it.

Yes, I always think it's so bloody weird that these blobs of grey jelly can formulate a thought (and, like, what even is a thought??), convert it into sounds and transmit that thought into other grey jellies, who then also have that thought, that new information. And we've collectively agreed on these sounds and their meanings, and come up with markings to represent them as well.

I mean, even the notion that every person who ever lived was an "I" with thoughts, fears, hopes, secrets, and that when we die those thoughts disappear forever, just... argh

Also, that whole idea about things being the last time you did something and you didn't even realise it at the time.

Like, I've seen numerous posts about 'One time, your parents put you down and never picked you up again.' or 'One time, you and your friends went out to play for the last time and didn't even realise it.'

Along the same lines, (sorry this is slightly grim), I remember reading a quote (I think from Tess of the d'Urbervilles) where it says about the important days of the year, birthdays etc. It points out that the day you're going to die is in the year somewhere. and every year you pass over that date without realising/ thinking about it. Which is true, if quite creepy and weird when you think about it! That quote always creeped me out and stayed with me.

Clapping.

We all bash our hands together when we like something

Once you've got that in your head you can't clap normally again

Space!!!!!! Weirds me out just thinking about it

@Mizydoscape i have thought this for so long but not been able to put it in to words but you nailed it!

@MrsMaryBOOface i have never even had this thought before but now i am lay in bed imagining my neighbours in bed like sims

I've always been quite bothered by cheese. The idea that someone in the past was so hungry mouldy cows milk looked appealing.

Dinosaurs also make my head hurt. The idea that massive monsters lived on this planet and that this planet is at least 250 million years old.

Lots of shit really, but the thing currently blowing my mind are fungi. The fact that there isn’t just one fungi, there will be a massive web of them all interconnected through a forest or field. And that they cause rain

@PutItInYourPocket
I remember a male workmate saying when I was pregnant ''Isn't it like having a parasite, like a tapeworm?''

I replied ''Not at all''.... Silly man.

Space as in, Solar system used to make me feel strange as a kid...

All that infinity, ending nowhere...The vastness of it made me feel quite strange : ''But it HAS to end somewhere?''... Evidently not.

That we drink milk from other mammals

I get the eating the flesh as we have killed it for that reason

But the milk is for their babies

Doesn’t stop me drinking milk I love it (cows milk) but it is odd

Acting. Why am I entertained by someone pretending to be someone else. I will literally sit and stare avidly at what I know to be a completely fake situation between people who are just pretending to be the people I'm watching. Such a weird thing.

I know in many ways bees are more impressive but I can't get over wasps nests. Those tiny mouths chew up bits of wood, make a sort of paper and then fashion it into a beautiful delicate structure full of lots of little rooms. Just WOW.

How do cds work, really?
And when you get those blank plastic discs in car parks, how on earth do they store all that information? Time in / paid... likewise chip and pin and contactless. Cheques made sense to me.

Three things I find weird...

-Having babies. The fact that 'you can make a whole new human being just from things you have around the house'. I read that as a quote somewhere and I'm paraphrasing it.

-The concept of money. That the only thing that really keeps money going is the belief in money. 'I have these metal discs and paper that I say have this value'. When you look at your account balance, you're just seeing a number on a screen.

-The writing system. It bears no relation to actual spoken language really. We just decided that this squiggle represented that sound (I'm massively oversimplifying of course, but you get the idea).

Used to live in a terraced house on an estate, so all the other houses were pretty much the same layout. I used to visualise us all like Sims

Meals. Who decided that you have three a day. Why do breakfast, lunch and dinner always vaguely stick to the same theme ie, cereal, sandwich, meat and two veg. Why is it not ok to have a chicken salad when you get up in the morning? I know anyone can eat whatever they like but really most people don't do they? Why don't people have apple crumble for lunch and cornflakes for dinner. Who made these rules? I want to know whose idea it all was!

The Big Bang. Nothing, not even time, existed before, then immediately everything came into being.

That if your brain were simple enough for you to understand you would be too simple to understand it. Mind blowing.

Wallpaper is weird, why do we bother to glue bits of paper onto our walls . I know it looks nice and have it in my house but still think it’s an odd thing to do.

It’s weird that one day I decided I wanted a pet so I went somewhere, looked at a cat and said yep I’ll take that one and now she just lives in my house with me. I wonder how weird it must have been for her too. She was born in one house, then I went to look at her and basically to her view stole her from her territory and took her to my territory to share it with me?

Oh also!! I said to my husband the other day how weird it must be for a Baby before they learn how to talk. Like living in a foreign world in which you don't understand anything.

Nerdy, but the concentration of oxygen in the atmosphere.

It's about 21%. Just high enough for combustion.

Not so high that the air could cause explosions and not so low that a spark can't become a flame.

We can survive on lower and higher oxygen levels, but fire can't.

Without that 'just so' amount of oxygen in the air, early man wouldn't have had fire, gathered round for warmth and companionship and cooked food.
