Great question! This is probably pretty mild compared to other scientists here, but I remember being genuinely surprised and finding it a little weird that the skin on your eardrum grows outward (like a conveyor belt) to shift earwax. People have drawn on eardrums and taken pictures over time of the dot moving along the ear canal! Don’t try at home 😉
The human body is amazing and there are loads of werid things about it. I think the weridest one I have heard is that we are bioluminescent (we produce light!) but its so weak our eyes can’t see it. How cool would that be if we could be a literal human torch!
Ooh thats a good question. And I love the answers so far!
My favourite is this:
Almost every cell in your body contains a nucleus – and this holds all your genetic material, your DNA etc. Now cells vary in size but are around 1-5 microns (0.001 of a mm). Each cell contains the entire DNA of your body, and it is curled up super tight.
But if you were to unwind the DNA all the way out and lay it out in a straight line – it would be over a metre long. (I’ve read anywhere between 130cm to 200cm). Every cell – so small you can’t even see them, has DNA long enough to stretch over a metre!
And if that wasn’t crazy enough if you took all the DNA in your body and stretched it out you’d have enough to stretch outside the solar system!
I never, ever, get tired of thinking about how amazing that is, how amazing our bodies our and how amazing life is.
Great question, I think one of the weirdest facts I learnt is that you are born with more bones than you will have as an adult. A baby has around 300 bones at both, but this total decreases to 206 bones by adulthood! What is your strangest fact?
