Something you didn’t know that blew your mind

My Dd1 had ALL 3 years ago and needed a stem cell transplant.
We knew that her DNA would change and she would have the same DNA as her donor.
However, she’s just spent 8 days in hospital with an infection that turned into pleurisy and suspected sepsis. (Thanks to the selfish bastard who thought going to see an immuno compromised person whilst ill was nothing to worry about)
What we didn’t know was that her blood group has changed, she was O positive, she’s now O negative! The nurse showed us her records where it says “After X date (date of her transplant) ALL blood products MUST be O neg”.

Science and medicine is amazing.
Is there anything you’ve learned that blew your mind?

@StormcloakNord
Not taking the Micky, but genuinely interested in what you thought was happening in the different phases of the moon if it wasn’t the sun shining on it.
My son asked me once if a crescent moon had been bitten!

The thing that took me a while to realise what that the dark side of the Moon is referring to the unknown side of the Moon (the side we never see), so it's not always in darkness - in fact, at a new Moon it's fully illuminated, and the side we see looks dark.

@Pinkyrosie also in Serbia the central heating is controlled by the government - in Belgrade anyway. It makes for some pretty toasty autumn and spring days if there’s unseasonably hot weather!

Zebras are black with white stripes.

There is only one lake in the Lake District

Not true. Ok so most of them are called tarns, meres etc, but those are just words for lake! It would be like saying 'There are no roads in my village' just because they all happened to be called XYZ Lane or XYZ Street. They are still roads, just like Windermere is a lake.

I'm not at all sure about skimmed milk being blue and having a chemical added to make it white..........

If you buy a bottle of full cream milk and syphon the cream from the top, what you have left in the bottle is skimmed milk. White - not Blue or Clear. No additive required to make it white.........

Things that blow my mind include:

Cow's milk is not the milk from just one cow, it is the milk of lots and lots of cows all mixed into one big soup. This is one of many reasons why I'm vegan.

All the water you drink has been drunk over and over before and passed through other bodies before you drink it.

Hardly anything ever leaves planet earth or arrives here. It's all just the same stuff moving about, being recycled, taking different forms.

Chemicals are just concentrations of natural substances. The source of everything is nature.

The moon is 400 times smaller than the sun, but coincidentally 400 times closer, so they appear about the same size. This make me think it's not a coincidence.

My mind is very easily blown.

@Awwlookatmybabyspider similar to your flamingo one-salmon. It's their diet that makes their flesh pink. I was involved in some of the early trials of organic farmed salmon and the first batch were white fleshed. Tasted like salmon but white!

I drive 2 cars and the petrol cap is on different sides on each and I can never remember which is which. I recently found out that next to the symbol of the petrol pump on the dashboard is a little arrow to show which side the cap is! Couldn’t believe I’ve never known this before

This seems to be true on modern cars, but hasn't always been the case. The first car I had, 25ish years ago, had the arrow pointing to the other side. My car wasn't new when I got it.

I suspect this is a case of fact following fiction, in that it became an urban myth that the arrow pointed to the side the filler cap was, and manufacturers just decided to follow that.

Females are born with all the eggs they'll ever have, which means when your DGM was pregnant with your DM, she was also technically carrying you.

This sounds so obvious but blew my mind.

Chemicals are just concentrations of natural substances. The source of everything is nature.

Chemicals are what everything is made of. Splitting an atom gives you chemicals that are not natural, or at least do not occur in nature on our planet.

What we call 'poison' actually depends on the dose. Chocolate is poisonous but we never eat enough one time to kill us. You can die from drinking too much water but it takes a lot in a small amount of time.

We are all made up of stardust, your left arm and right arm might be made from different stars.

In addition to some wine being vegan, Guinness is vegan too.
Something to do with not using animal products in the brewing now.
Doesn't take a lot to blow my mind 😊

Awwlookatmybabyspider I think there's an element of truth in the retaining dna theory from multiple partners. I overheard a Dr. couldn't avoid it tbh telling the lady similar in the cubicle next to me. The Dr. thought it could be the cause of the lady's miscarriage as her body didn't recognise the 'unknown' DNA from her new partner. The lady had 4 children from 4 separate fathers so there was a lot of different DNA involved. Who knows.

If we for some reason retained DNA from men we sleep with, this would be true with everything else as well. So every time you eat, you become a little more potato? I don't think so.

Skimmed milk is not clear. If you get non-homogenised milk straight from a cow, like we did when I was a kid, it will separate and skim the cream off. While it will look slightly blueish next to the cream, the milk is still very much white.

Skimmed milk definitely doesn't have anything added to it.

I know this because I used to bottle the milk from our cows in the dairy. We bottled/produced whole, semi-skimmed and skimmed milk. Nothing is added.

Plus, if something was added it would be on the ingredients list.

There are more trees on earth than stars in our galaxy.
🤯 This fact makes me feel warm and fuzzy!

All of the planets could fit between earth and the moon!

Dinosaurs and humans never roamed the planet at the same time. Was a genuine "holy shit" moment for me. Bloody Flintstones.

@GenuineKlatchianPottery
Your post blew my mind!! I have been looking at the dog ever since thinking "she knows what I am thinking"

Thank you for that amazing post, it will stay with me. Some brilliant posts here.

I haven't much to add, if you break a peanut open very carefully you can see a tiny little nut bunny rabbit in the middle at the bottom.

@FreshwaterBay that was your post about the animals I was talking about, thank you again.

G5000 like I said who knows for sure but the Dr. seemed to consider it as a possibility. The body retains the dna from previous pregnancies and develops a system to prevent it from rejecting a baby with recognised dna. She went on to say it was because the lady had babies from multiple men that this issue occurred.

I'm not a Dr. & maybe somebody more experienced will come along & explain it. The conversation took place in the cubicle next to me separated by a curtain so not very private.

@Awwlookatmybabyspider that's just blown my mind

@meridaofthefabulousredhair I used live in the Dandenong ranges! They're so high & its constantly raining that I'd believe that!

When you snap your fingers the snap actually comes from the sound of your finger hitting your palm.
When you purse your lips to blow air it comes out cold, when you have your mouth open it's hot.

@Aberhonddu it also coats m and ms, under the coloured bit

"
Plus, if something was added it would be on the ingredients list."
This sounds very sensible

Was it the thin cows you got the Skimmed milk from? ;)
