No matter how many books you read, there is always something that can totally change your perception of even the most ordinary things. A Reddit user asked this question, “Which 2 and 2 did you just recently put together?” and people shared their new discoveries. You may even feel awkward while reading some of them, because they’re a surprise to you too.
Honestly speaking, many of these replies were pretty unexpected, even for us at Bright Side — and we write about all sorts of things, every day. This article includes not only the user’s discoveries, but also some of our own.
- The blacks of the eye are black because there’s nothing there. It’s just a hole. You’re seeing the inside of the eyeball, but you can’t see anything because there’s no light in there. © Zorafin

- Sonic the Hedgehog’s best friend is named Miles Prower. “Miles Per Hour.” Why did it take me 30 years to realize this? © TheMike85

- That dog units are called K-9 because they are canines. © Lars2500
- Macintosh is a type of apple. Now I see why Apple named their computers this way. © exuseus
- Sweatbands worn on your wrist are used for wiping the sweat off your forehead… I thought they were to keep the sweat from dripping down your arms and onto your hands. © YaBooni

- At the age of 26, I realized that Russia and the US are very close and I used to think that we were in different parts of the world. These 2 countries are much closer to each other than I thought. The closest point is in the Bering Strait, so the distance between the countries is just 2.4 miles. © ripppy
- The second pilot is not some kind of assistant. He is just as much a pilot as the first one.
- The stripes on the back window of a car heat it. They are metal threads that transmit electricity. © emmyjoe311

- Alphabet = Alpha Beta. Apparently, everyone knows this. I’m in my forties… The name comes from the first 2 letters of the Greek alphabet. Most languages have this word, and it sounds similar regardless of the language it’s spoken in. © SaskatoonRJ
- Not extremely recently, but it took me 21 years to notice that my birthday is exactly 9 months after Valentine’s Day. I’m a product of love. According to science, this is not for sure, but the probability is very high. Try to calculate, maybe 9 months before you were born, it was some interesting date. © ginelectonica
- Hens don’t need a rooster to lay eggs. More than that, we mostly eat these types of eggs. The eggs made by a hen without a rooster have fewer calories, but a chick can’t hatch from them. © SlummyBummy

- The “I” and “O” on the power switch of a computer (and many other electronics) is actually a 1 and 0 for the binary settings “On” and “Off.” It is easier to memorize if you realize this fact. If a button serves for both functions (like on a remote) both signs will be there. © Solest044

- Up until recently, I did not know that Ctrl + Backspace cleared a whole word — thinking about the number of times I’ve unnecessarily hit that key in my life makes me physically sick. © BasiKs
- The holes at the bottom of a padlock are there to allow water to leak out.
- I’m 32. I didn’t realize soap doesn’t kill bacteria. It just makes it slippery so the bacteria wash off. My wife had a good laugh at me when I realized that. Molecules have interesting properties: one side repels water and the other one attracts it (like a magnet). So, when washing hands, the first side collects all the bacteria and dirt and the second one is ready to remove all the mess once the water stars pouring over them. © islanders571

- Ray Bans ban rays from your eyes. I’m embarrassed to admit I thought a guy named Raymond Ban owned a sunglasses business. © KarlMalownz
- Saul Goodman = it’s all good, man. I’m mind-blown. It clicked after watching all 5 seasons of Breaking Bad. Twice. © besteni
