We humans are curious creatures. For example, according to one survey, 73% of American adults consider themselves lifelong learners.

For the most part, they go about it in traditional places — at home, work, conferences, or various institutions such as government agencies or libraries. But through it all, the internet remains an important tool. So let's see what these folks have to share.

A few days ago, Reddit user Clean-Youth8369 asked everyone else on the platform, "What's one thing you accidentally found out that now everyone has to know?" and has received over 8,000 replies.

From hard sociologic data to human behavior tendencies, and even wholesome personal observations, here are the ones that got the most upvotes.

The actual things that happen when you declaw a cat. It’s like amputating fingers. They often get early arthritis and back problems because it changes the way they walk completely. It’s insanely barbaric and any vet who participates in the practice knowing the results is immoral and evil.

You have to get revaccinated for whooping cough as an adult. I didn’t know this until I caught whooping cough in my late 30s. It was honestly one of the worst things I’ve ever been through. I slept outside in a tent as I was keeping everyone awake. I would cough until I either vomited or passed out, and this went on for weeks. I broke a rib and split intercostal muscles. You’re supposed to have boosters every 8 - 10 years as an adult, and it really made me understand how babies and small children can and do die from the infection.

It starts out very much like a simple cold, slightly sore throat and runny nose. It then progressively gets worse with a cough and tightness in the chest.

Now, every time I get a slight cold, I produce a horrible cough that sounds like a braying donkey, even when I feel fine. I wish I knew about needed to get a booster vaccine, now I tell everyone!

Sudden hearing loss.  It happens overnight in one ear, can happen at any age and they don’t know the cause. But if they treat it in 48 hours you have a good chance of it returning- the longer you wait the less likely you’ll recover anything.

If there’s some sort of horrific injury at an accident scene, like a limb sliced off or a decapitation, emergency workers who are first on the scene will warn the other workers on their way so they can mentally prepare for it.

So if you’re reporting an accident, be explicit in describing injuries so your people can prepare.

When putting your fitted sheet on your bed go opposite corner to opposite corner. Like youre making an x. All my life I’ve struggled with the fitted sheet coming off the mattress and my bed sheets becoming a mess until a few weeks ago when I read a comment on Reddit. It’s changed my sleep and comfort in my bed.

i don't know why this blows my mind. but if you have a problem with working out a percentage, flip the numbers and see if it makes more sense.

5% of 200 is the same as 200% of 5,
80% of 50 is the same as 50% of 80.

Try it. It's awesome!

I have aphantasia, didn't figure it out until I was in my 30s. I thought when people said like imagine or picture something it was a figure of speech. Had no idea everyone has brain pictures and a very small percentage of people have no visual imagination or what's called aphantasia.
