The world is a big, wonderful place full of facts we never thought possible. For instance, if a pregnant mouse has a sudden medical issue, the fetus will send stem cells to heal the mother, increasing its chances of survival as well. Fetal stem cells have been found in human mothers as well, dubbed by science as microchimerism.
Bright Side dug up some more marvelous facts about nature and its creations, upholding our yearly resolutions to spread knowledge and joy.
1. The heart slows when your face touches water.
As mammals, we can’t breathe underwater, so as part of the mammalian dive reflex, our heart rate goes down in the water — more so if we go underwater. Even splashing the face with water makes the heart slow down, making it a great way to calm down.
2. Fungus can break down plastic in weeks.
It is said that in the future, there may be more plastic in the ocean than fish. This is why the plastic-eating fungus is great news, and there are around 50 new species of such fungi discovered already. One of the fungi discovered can digest plastic within 2 months, so there’s hope for us yet.
3. Newborn babies can support their own weight.
Newborn babies are strong — strong enough to be able to grasp things in their tiny fists and even support their weight as shown by an experiment done in the nineteenth century. Louis Robinson witnessed babies able to hang from a walking stick, from 10 seconds to 2 minutes and 35 seconds.
4. Koala fingerprints have been mistaken for human ones.
We’ve been told that our fingerprints are unique, and they are. But the fact remains that even though we share a common ancestor with the koala that was alive 100 million years ago, koala fingerprints look very similar to human fingerprints, as do chimpanzee fingerprints for that matter.
5. Snails can sleep for 3 years.
If you thought bears had it good with hibernation, meet the snail. Snails can sleep rather than hibernate for 3 years at a time without needing food. Of course, this is with some snail species, not all of them. Meanwhile, bears usually hibernate for just 4-8 months.
6. Sloths need 2 weeks to digest food.
Sloths don’t only move in slow motion — even their insides move slowly, ostensibly to preserve energy, which is why a sloth’s digestive system takes 2 weeks to process the food it ate. Plus, most of what it eats is indigestible, giving it very little energy from each slowly chewed mouthful.
On the other end of the spectrum lies the shrew, whose digestion takes mere minutes and is done so fast, not much of it is fully digested. This is the reason why shrews eat their own feces. They can die of starvation in a matter of hours if they don’t eat.
7. Your brain ignores seeing your nose.
We can see our nose all the time, it’s just that the brain tends to ignore it because it’s a constant visual stimulus. It’s the same with people who wear glasses. After a while, they simply stop noticing them.
8. Your forearm is the same length as your foot.
If you don’t have the time to try on a shoe, measure it from your elbow crease to your wrist. If it fits or is just a little smaller, it would fit your foot because the length of your forearm is the same as your foot. And this is just one of many human body ratios that are a marvel in themselves, including the fact that your femur bone is one-quarter your height.
9. You can “see” your white blood cells.
If you look up at a cloudless, bright blue sky and see some wiggly things at the periphery of your vision, you’ve just experienced the blue field entoptic phenomenon. The wiggly things are white blood cells moving in the fine blood vessels moving in front of the retina, at the back of the eye.
10. Human beings have striped skin, but only cats can see it.
Human beings have stripes and patterns on the skin too, and they are called Lines of Blaschko, name eponymously by the scientist who discovered them, Dr. Alfred Blaschko. These are closer to tiger stripes, forming more of a V-pattern fanning out from the center to the extremities. These lines are visible under UV light, a spectrum that cats can see too, which is why cats can see you as a striped being as well.

Matt Heath: My parting message: Enjoy things while they are around
A lot of big, tragic and important things have happened to this wonderful country of ours since April 2014. None of which I have covered. I was too busy writing about hungover parenting, ancient philosophy and my dog Colin.
Out of the 536 columns I have written, 27 were about that guy. Far too few. He is such a good boy, he deserves an article a week.
Today is the end of an era for me, and whenever these final events pop up in our lives, we can’t help but think about the ultimate end.
Everything we do, we will one day do for the last time. That’s why you have to enjoy things while they are around. It’s not just big events like leaving a job, house or loved one either. Whatever moment you happen to be in now, you will never get it back, and you don’t know how many more you have.
Everything we do in life, from eating pizza to spending time with the people we love, to driving, writing, drinking or breathing, we will one day experience for the final time. It might happen tomorrow. This can be either a depressing or an inspiring thought, depending on how you look at it.
A few years back in this column, I interviewed professor of philosophy William B Irvine, of Wright State University, Ohio, on this very topic. He put it this way on a Zoom call: “Recognition of the impermanence of everything in life can invest the things we do with a significance and intensity that would otherwise be absent. The only way we can be truly alive is if we make it our business periodically to entertain thoughts of the end.”
Today’s column is very meaningful to me because it is my last. Like the last night with a lover before she goes overseas. And just like a lover, there have been some half-arsed efforts put in from me over the years. Last week, for example, I spent 750 words moaning about how bad my cricket team is. But the truth is that any of my columns could have been the final. If I had reminded myself every week for the past 10 years that the end is inevitable, I may have been more grateful for having a column and appreciated writing them all as much as I am this one.
While everything we do could have more meaning with a focus on finitude, some things are inherently more worthwhile than others. There is no doubt my column “The pros and cons of wearing Speedos” from November 2022 was less meaningful than most things in this world. That was a waste of everyone’s time. So, if we only have so much time, how do we pick the best things to do?
Well, Oliver Burkeman, the author of Four Thousand Weeks – Time Management For Mortals, suggested this to me in a 2022 column: “Ask yourself, does this choice enlarge me? You usually know on some unspoken level if it does. That’s a good way to distinguish between options.”
With that in mind, I don’t feel great about my 2018 article on “New Zealand’s best hole”. That didn’t enlarge anyone.
There will be people reading this column right now who have loved my writing in the Herald and are sad to see it end. Others will have hated it and are glad to see me go. Many won’t have any opinion at all. But for those in the first camp, I have good news. I have a book coming out on May 28 called A Life Less Punishing – 13 Ways To Love The Life You Got (Allen and Unwin Book Publishers). It’s a deep dive into the history, philosophy and science of not wasting our time lost in anger, loneliness, humiliation, stress, fear, boredom and all the other ways we find to not enjoy perfectly good lives. It’s available for pre-order right now (google it if you’re interested).
A Life Less Punishing took me two years to write and is equivalent in words to 100 of these columns. Which would be a complete nightmare for those in the hate camp, but as I say, great news for those who want more.
Anyway, thanks to the Herald for having me, thanks to the lovely people who make an effort to say nice things to me about my column nearly every day and thanks to the universe for every single second we get.
Bless!
