60 Happy Facts That Are Actually True

Happy facts work better when they are true. Most lists of them are not, which is why this one was pulled apart and rebuilt in August 2026. The myths came out, the shaky numbers were checked against a source, and what is left is sixty facts that survive being looked up.

Cute, wholesome, feel-good and occasionally very strange. Take one as your fact of the day, read the lot in five minutes, or take the one about the squirrels and think about it for the rest of the week.

Animals turn out to be stranger, kinder and better organised than anyone tells you

1. A group of flamingos is called a flamboyance.

2. Millions of trees grow every year because squirrels bury nuts and then forget where they put them.

3. Many penguin species return to the same mate season after season. Emperor penguin males hold the egg on their feet through the Antarctic winter while the female feeds at sea.

4. There is an antelope called a dik-dik. It is roughly the size of a cat and it has enormous eyes.

5. Sea otters hold hands while they sleep so they do not drift apart.

6. One jellyfish can reverse its own ageing. Turritopsis dohrnii reverts to its juvenile form when it is injured or starved, which in principle makes it biologically immortal.

7. Butterflies taste with their feet.

8. Rats laugh when tickled. The sound sits above the range of human hearing so you need equipment to catch it, but the response is real and it is repeatable.

9. Seahorses often keep the same partner and swim together with their tails linked.

10. Puppies handicap themselves during play. The bigger one holds back so that the game carries on.

11. Cows have best friends. Put a cow beside its preferred companion and its heart rate drops.

12. A group of porcupines is a prickle.

13. Sloths climb all the way down from their tree about once a week, purely to go to the toilet.

14. Dolphins sleep with half the brain at a time. One eye stays open and on watch.

15. Cows give slightly more milk when someone plays them slow music. Researchers at the University of Leicester measured about half a litre a day more for slow tempo tracks than for fast ones.

16. Scotland’s national animal is the unicorn.

17. Outside the nesting season the common swift stays in the air. It drinks, feeds, mates and sleeps on the wing, and tracking studies have recorded birds staying aloft for ten months without landing once.

18. Baby rabbits are called kittens.

19. Baby puffins are called pufflings.

20. A group of hummingbirds is a charm.

21. Push a sea sponge through a fine mesh and the separated cells find one another and rebuild the sponge. Henry Van Peters Wilson demonstrated it in 1907 and it still sounds made up.

People keep quietly doing decent things and almost none of it ever makes the news

22. A rural station in Hokkaido, Kyu-Shirataki, stayed open until the single high school student who used it had finished school. It closed in March 2016, the month she graduated.

23. On the day he was killed, Martin Luther King Jr had a pillow fight with friends in his motel room.

24. Mister Rogers answered his fan mail. All of it, for decades.

25. Volvo patented the three-point seatbelt in 1959 and then gave the patent away so that every other manufacturer could use it.

26. Apollo 17 astronaut Gene Cernan wrote his daughter’s initials in the lunar dust. With no wind and no water up there, they should still be legible in fifty thousand years.

27. Wayne Allwine and Russi Taylor, the voices of Mickey and Minnie Mouse, were married to each other in real life.

28. The Netherlands sends thousands of tulip bulbs to Canada every year. It has done so since 1945, as thanks for sheltering the Dutch royal family and helping liberate the country.

29. In Istanbul, vending machines dispense food and water for stray dogs in exchange for recycled plastic bottles.

30. Bhutan has measured gross national happiness alongside its economy since the 1970s.

31. There are more public libraries in the United States than there are McDonald’s restaurants in the United States.

32. Norway has a knighted penguin. Sir Nils Olav lives at Edinburgh Zoo and holds the rank of brigadier in the Norwegian King’s Guard.

33. Tolkien invented a word for the opposite of catastrophe. Eucatastrophe: the sudden turn near the end where everything comes right.

34. Handshakes are thought to have begun as a way of showing that you were not holding a weapon.

35. Finland has been named the happiest country in the world every year since 2018. Finns receive the news each March with visible embarrassment.

36. The smiley face was proposed by Scott Fahlman in a Carnegie Mellon message board post in 1982, purely so that people would stop misreading jokes.

37. Sikh gurdwaras run langar, a free kitchen that feeds anyone who walks in, with no questions asked about who they are.

The world got measurably better in the last few decades and the numbers are not close

38. The cancer death rate in the United States has fallen 34 percent from its 1991 peak. The American Cancer Society puts that at 4.8 million deaths that did not happen.

39. Smallpox is gone. Outside two secured laboratory freezers it no longer exists anywhere, and nobody will ever die of it again.

40. The hole in the ozone layer is closing. On current trends it should be back to 1980 levels around the middle of this century.

41. Global life expectancy has more than doubled over the past hundred years.

42. Extreme poverty has fallen faster over the last forty years than at any point in recorded history.

43. Guinea worm disease has gone from roughly 3.5 million cases a year in the 1980s to a number small enough to list individually.

44. We are living in the future people used to write stories about. Space travel, a library in your pocket, video calls across oceans, all of it treated as unremarkable.

Your own body is doing several things right now that you would refuse to believe on paper

45. The nitrogen in your DNA, the calcium in your teeth and the iron in your blood were all made inside collapsing stars. You are made of star dust and that is the literal version, not the poetic one.

46. Not one of your direct ancestors died childless. Every single one of them, the whole way back, managed it.

47. Cuddling releases oxytocin, which lowers stress hormones and has been associated with faster wound healing.

48. Smiling and frowning use roughly the same number of muscles. The old line about seventeen against forty-three has no anatomical source and the figures change with every telling. Smiling still lifts your mood, which was always the useful part of the claim.

49. Watching someone else smile makes you more likely to smile back, and more likely to feel better, before you have consciously decided anything about it.

50. You spent about a day of your life as a single cell.

51. Under sudden threat the brain records far more detail than usual. Time does not actually slow down. It simply leaves you with more to remember, which afterwards feels like the same thing.

52. At the moment you were born you were briefly the youngest person alive.

53. Music that gives you chills is triggering a dopamine release. The shiver down the back of your neck is chemistry.

Small joys, useful words and several things that are true for no particular reason at all

54. A group of pugs is a grumble.

55. There is a word for someone who loves rain. It is pluviophile. Ombrophile gets used for the same thing but it belongs to botany and means a plant that thrives in heavy rainfall.

56. Nibling is the word for a niece or a nephew when you would rather not specify.

57. Saying “my cocaine” out loud makes you sound like Michael Caine introducing himself.

58. Count upward through the numbers and, counting the British way, the letter A does not appear until you reach one thousand.

59. There will always be a food you have not tried yet.

60. Happiness behaves like a skill rather than a setting. The habits that produce it can be practised, which means the current reading is not the permanent one.

What changed in this list, and why several old favourites are no longer in it

This list first ran in 2013 and readers spent a decade politely pointing out the holes in it. They were right. The pig, the muscle count, the Beatles tally and the line about matter lasting since the beginning of time have all gone, because none of them survive a check. A few others were corrected rather than cut, which felt more honest than quietly deleting them.

If a cheerful fact cannot take five minutes of scrutiny then it is not cheerful, it is just wrong.

There are more where these came from in our second collection of happy facts, and in thirteen wonderfully weird facts about our wonderfully weird world. For more cheerful reading, discover how Finland’s terrifying Christmas goat became the world’s most beloved Santa, explore why Isaac Asimov is the greatest sci-fi writer ever, or check out 13 celebrities you never knew were Finnish Americans.

Finland has topped the World Happiness Report for nine years running, which Finns themselves tend to receive with polite scepticism. If you want to understand what Finnish happiness actually looks like from the inside, Joel Willans’ 101 Very Finnish Problems is a brilliantly funny place to start.
