1. You can "eat" garlic with your feet.

Even if you block out the smell of garlic by rubbing garlic on the soles of your feet with a plastic bag or something similar, you will still be able to "taste" the garlic in your mouth and nose about half an hour later.

Why is that? It turns out that garlic contains a substance called "allicin," which has extremely strong penetrating power. It can pass through our skin, enter the bloodstream, and then reach our mouth and nasal cavity, which is why we can "taste" and "smell" garlic.

2. The Strange Origin of "OK"

"OK" is one of the most widely used and common words in the world, but did you know that this word originated from a mistaken joke? Around the 19th century, someone started spelling "all correct" as "oll korrect," and then simplified it to "OK," just like how we now use "酱紫" to mean "like this."

Later, in 1839, the editor of the Boston Morning Post first used the word in a newspaper article, and from then on, the word OK spread.

3. Elephants are the only mammals that cannot jump.

Elephants cannot jump not because of their large size, but because their bones are too dense and the gaps between them are small. This results in poor limb flexibility and a lack of the elastic structure needed to jump.

4. Mario doesn't smash bricks with his head.

Mario games are a childhood memory for many people. Many people probably think that Mario smashes bricks with his head, but in fact, Mario does not have an iron head. If you look closely, you will find that he smashes the bricks with his hands.

5. People in the Victorian era were already "beautifying" photos.

Nowadays, using beauty filters in photos is commonplace; some people even feel embarrassed to post on social media without them. But did you know that people were already using beauty filters as early as the Victorian era?

However, back then there were no beauty apps, so people could only use "physical" methods to enhance their appearance. They would scrape photos with razor blades to make their waists appear slimmer, or use pencils and paint to create more perfect skin. It seems the desire for beauty is truly ingrained in human DNA.

6. A zebra is a black horse with white stripes.

We all know that zebras have black and white stripes, but have you ever wondered whether a zebra is a black horse with white stripes or a white horse with black stripes?

Scientists have shown that zebras are actually pure black in the early stages of embryonic development. However, in the later stages of embryonic development, melanin production is inhibited, resulting in white stripes. Therefore, zebras are actually black with white stripes. Furthermore, each zebra's stripes are unique, allowing them to recognize each other.

7. Applying adhesive tape to frosted glass will make it transparent.

The principle behind frosted glass is that its surface is made uneven, causing diffuse reflection of light, making it difficult to see the other side. However, after applying a layer of tape, it becomes transparent. This is because the tape smooths the uneven surface of the glass, reducing diffuse reflection and allowing you to see the other side.

8. Agatha Christie's novels have sold over 2 billion copies.

Agatha Christie, the "Queen of Crime" from Britain, is the best-selling popular literature author in human history. Her detective novels have sold over 2 billion copies since their inception, earning her a Guinness World Record (2000). Only the Bible and the works of Shakespeare surpass her achievements. Her novels have been adapted into films numerous times, such as *Murder on the Orient Express* and *Death on the Nile*. Have you read any of Agatha Christie's novels?

9. In Europe, mummies were once used as medicine.

Mummification was a method used by the ancient Egyptians to preserve corpses. However, when it reached Europe, for some reason, rumors arose that mummies had "high nutritional value" and could cure diseases.

This sparked a mummification craze in Europe, with large quantities of mummies being exhumed and shipped to the continent, leading to a temporary shortage of supplies. Lured by money, some unscrupulous merchants even used newly made mummies or animal carcasses to impersonate mummies.

Europeans were misled for centuries until the early 20th century, when modern medicine began to develop and this "medicine" was finally abandoned by Europeans.

10. Between 10% and 30% of people sneeze when looking at the sun.

This phenomenon is known as "ACHOO syndrome," also called "autosomal dominant forced sunlight burst," a genetic disease controlled by a dominant gene.

It's okay if you don't understand the terminology, because it describes a very simple and common phenomenon: when suddenly exposed to strong light or looking up at the sun, some people immediately feel an itchy nose, want to sneeze, or even can't control sneezing. This is what "ACHOO syndrome" means.

However, there's no need to worry too much. Although it sounds like a genetic disease, apart from sneezing when exposed to bright light, it doesn't cause any other harm.
