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?

That all of the gas planets have rings, not just saturn

I’m almost 30 and only just found out this summer that cows are all female. I also didn’t know that bulls were all male and that you bred cows with bulls to make baby cows/bulls. I just though they were different animals. So bad

I didn't know that such a thing as salivary gland stones existed until a couple of years ago when I had one. They are calcified lumps that pass through the salivary glands and come out in the mouth. I am currently suffering from one at the minute. When I eat the side of my neck swells up because the saliva can't get through until the stone pops out. Eugh!! It is also very painful.

@captainprincess apparently sometimes it is the side of the arm on the petrol pump which acts as the indicator. I can't remember whether there was one in my old car

That when salmon swim up river to spawn they are gradually killed by a combination of swimming in fresh water not salt water and because they stop eating, so they die after spawning. And their mate swims with them so they die too. I found this out this year and it’s so sad I didn’t want to believe it.

Bees sting other bees

Scotland's national animal is the unicorn 🦄. How cool is that?

I read the thing about DNA and unprotected sex. Can’t remember all the details but I do recall that after 3yrs of regular, unprotected sex with a man, the woman becomes a better bet than even close relatives of his for a kidney donation. This remains the case if not forever, for a long time, even if the sex stops.

For cliffdiver and her ilk

Mrswhiplington, DS suffers from salivary gland stones, he's actually had some removed as they wouldn't pop out, he was in so much pain, so you have my sympathy.

OMGshefoundmeout The Salmon run is both sad & amazing to see.Its due to happen very soon, the river is full of Salmon and then within a few days it is full of dead salmon. The smell is intense. Its also a grest time if year to watch the Bears & Eagles feeding side by side at the river

Many moons ago when dp was a teen he drove through dandenong mountain ranges with a mate and actually drove through a 🌈.

He says it's like standing in the middle of a crystal and as the sun hits the crystal all these little colourful sparks light up all around you and also a bit like the sun reflecting off the spray from a waterfall when the sun is high in the sky.

I find it lovely to think that some of my daughters cells are still in my body. She has permanently changed me in more than one way.

Thank you @elQuintoConyo

Sorry but there's a lot of shite here. The Lake District is full of bloody lakes and hair & nails grow faster in hot weather.

There is a book with no Letter Es I’m aside from the Authors name.

If you were to count all the stars in the galaxy it would take you 4,000 years.

32 years is the equivalent to 1 billion seconds.

@OriginofSpecies you have to dip your headlights in fog, not use bright front lights. Fog reflects light back at you, so brighter light actually reduces your visibility.

MissLadyM that one is actually true, it is due to their size, they have different names depending on their size so only one is a true lake. Not sure about pink hippo milk though, (widely disproven)

Aluminium is easily recyclable

Is the lake thing Cumbrian?as opposed to size.

There are 16 large bodies of water in the Lake District, 15 are something mere or something water e.g. Windermere obviously and Coniston Water, I think that’s one, if not, Derwent?

Pretty sure you can’t drive through a rainbow. A rainbow moves as you move because it’s just your perception of sunlight on water, not an actual physical thing.

A rainbow is a circle. It's something I already knew but I saw a double rainbow from an airplane and it was very pretty.

The DN and sex and being a transplant match is shere shite though.

Oh and blood is red, it is always red, never blue (in humans, some crabs have blue blood)cutting yourself is not oxidation. I have had to teach this far too many times to people who have GCSE science.

@Mileymileymoomoo

I always think that could partly be why mothers and their daughters often become closer around the time grandchildren appear, and why women often feel closer to their daughters’ children than their sons’. They can’t help it, it’s like they “recognise” these grandchildren in some way.

@AthollPlace that makes sense also.

@TinklyLittleLaugh don't be so rude. Yes you can.
