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

I've read more than one author, I've had sex with more than one man. I tend not to read two books at the same time, or have sex with more than one man.

And lots of people who get noted of it pick up a side book or throw their book in the bin and get a new one.

From an evolutionary perspective it makes sense that you know which man fathered your baby so he can go fetch you mammoth curry for dinner

Monogamy. Imagine just reading one author all your life. Yet we all do it and all get bored with it and stay through some sense of morality

The logistic industry. How do they work out who needs what where? I say this as an HGV driver of three decades. Quite frequently I'll get a job that makes me think people are burning diesel for something that could go in a van.

Lots of thought provoking comments here. I went to see Brian Cox the physicist when he did a UK tour a while ago & it just blows my mind how intelligent he is & all the things he spoke about.

One thing that I’ve always found weird is Bluetooth. The fact that I can have music on my phone that will then play on a speaker that isn’t wired to my phone. I love technology, always been into computers & tech since I was a child, but this is still something that I can’t get my head round 😂

How many ways there are of pronouncing the letters ough. Rough, cough, bough, dough.

@cushioncovers IIRC it's because women naturally have more contrast between our eyes/mouth and our skin. This is why we use makeup to further increase this contrast and look more feminine.

Religion - That otherwise sane and intelligent people can believe in a god with no evidence, & spend their whole lives following a bunch of random rules that they think this god made.

@JaJaDingDong

How do you pronounce them differently? Is it dialect or are you the only one?

@MrsAvocet in my previous job we used to digitally sign documents and if any changes were made you'd need the chain of approval to re-sign.
I would get twitchy if people asked me to resign.

I went to the Paper Mill museum in Basel and learnt that what direction you write in (left to right, top to bottom) and how your letters are formed (straight lines or curvy ones) was driven to a large extent by what materials were used to make paper and what worked best for each medium.
Fascinating

Here's a minor strange thing that I noticed this morning. I was writing that I was pleased to hear that a professional sportswoman that I follow has signed a new contract with her team. So I wrote that I was glad that she had resigned. Then changed it to re-signed. Adding the hyphen makes the words mean more or less the opposite of each other. How did the word for leaving a post come to be the same as signing on again? I'd never noticed before.

Different colour perceptions

www.gondwana-collection.com/blog/how-do-namibian-himbas-see-colour/

Westerners can't easily tell which green square is a different colour in the first circle.
The Himba tribe can't easily detect the blue square

Also the English language using the same sounding words for different things but have different spellings e.g. there and their, meet and meat, flower and flour. Trying to explain the difference between there and their and why they are spelled differently to a 6 year old is fun

I pronounce there and their and flower and flour differently

They don't just hump any passing female for fun

Neither do humans, though. The pheromones have to right for us, too. It's just that humans are in season to some degree or another most of the time.

Re the sex thing - I often wonder when mankind worked out that pregnancy is caused by a sex act. It's not immediately apparent that your pregnant after having sex. Some women don't notice for months that they are pregnant.
I know "maidens" don't get pregnant, but when did we realise what causes it?

And how do we automatically know if a persons face is male or female? If you scrape their hair back and just see a photo of the face not the neck or body, nor the hair style etc you can still recognise most people as either male or female despite the fact that it's just eyes nose and a mouth you're looking at.

The fact that each month a woman releases a different egg so if you fall pregnant in October for example you will have a child that is completely different from a child that was conceived in September.

Why women who spend a lot of time together their periods start to sync

DD and I haven't synced over the last 3 years. Which surprised me. Mine are still in a similar cycle to what they have always been (although I must be nearing the end, surely!) and hers is a week longer. I wonder if it is because I'm old.

Do we know this? I mean, biological urges have to be fun don't they?

I don't think they do it just for fun like humans do (it is what I understand from assorted documentaries, I don't know of any actual research!). E.g. Male dogs search out females who are on heat, so ready to procreate. They don't just hump any passing female for fun (although bedding, cushions and human legs are fair game). Although I think they have proved there are gay animals so who knows...

@ghoulyghosttunnel also tongue curling

In The Red Tent, set around Joseph and his Technicolour Dreamcoat era but from the women's side, they all go off to the Red Tent for a week and take it in turns to bleed into the hay, isolated fr the men as they're dirty. I guess they're safer and he's likely to only go shag an animal not your sister

Ears are weird @JocastaElastic. The fact that we are supposed to hear from them but have all that yucky wax inside which must stop us hearing as much.
Also earlobes. The fact that every single person on earth has either a dangling earlobe or a joined to the head earlobe depending on ancestry. Blew my mind when I found out. Now on telly I look to see how many dangler or joined earlobes there are on any programme. Danglers winning so far. I'm a dangler.
