This video discusses five unusual topics. First, it explores the origin of the expression "comparing apples and oranges," which is often used to convey that two things are not similar. However, the speaker points out that apples and oranges do share some similarities.
The second topic is "technological hallucinations," where people perceive things that aren't there, such as thinking their phone is ringing or vibrating when it's not. This phenomenon is known as "phantom vibration syndrome" and is more common in people who are highly attached to their phones.
The third topic is about a prison program in the US where inmates are allowed to adopt cats. Despite initial concerns, the program has been successful in reducing stress and violence among prisoners.
The fourth topic is about "quantum speed reading," a scam that claims to teach people how to read quickly by turning pages fast or even with their eyes closed. The speaker debunks this claim, explaining that research has shown that reading comprehension decreases significantly when reading speed increases.
The final topic is about the "Manchineel tree," also known as the "tree of death." This tree is highly toxic, and its sap can cause skin irritation and burning. The fruit is also poisonous and can be deadly if ingested. Despite its toxicity, the tree has been used by some animals, such as iguanas, which are immune to its poison.
Here are the key facts extracted from the text:
1. The expression "comparing apples with oranges" is used to imply that two objects, ideas, or situations are not related.
2. This expression is used in many countries, but the comparison may be different, such as comparing bananas or carrots.
3. Apples and oranges are actually comparable in many ways, including their weight, edibility, and sugar content.
4. In old French, oranges were referred to as "lunch apples" because they were not yet known by their current name.
5. In some languages, "apple" is used as a term for all fruits.
6. In modern Swedish, oranges are referred to as "orange apples".
7. The concept of "phantom vibration syndrome" occurs when people mistake other noises or sensations for a vibrating phone.
8. This phenomenon is more common in people who are highly attached to their mobile phones.
9. It is possible to reduce the occurrence of phantom vibrations by changing one's habits, such as changing the ringtone or pocket.
10. Some prisons in the US allow inmates to adopt cats, which has been shown to reduce stress and violence among prisoners.
11. The most popular cat adoption program for prisoners is in Indiana.
12. Inmates who adopt cats are required to take care of them and can lose privileges if they fail to do so.
13. The concept of "quantum speed reading" is a scam that claims to teach people how to read quickly by turning pages or even with their eyes closed.
14. The average reading speed is between 200-300 words per minute, and increasing speed often harms comprehension.
15. The eye cannot cover more than 1000 words at a time, making it impossible to read 100,000 words per minute.
16. The scam of quantum speed reading was created by a Japanese teacher named Yumiko Tobita in 2006.
17. Tobita charges 220,000 yen for her seminars and 1,800 euros for online classes.
18. There is a tree called "manzanillo mirado" or "tree of death" that is highly toxic and can cause severe irritation and even death if ingested.
19. The sap of the tree can cause skin irritation, and the fruit is deadly to most animals that eat it.
20. The tree is camouflaged and can be found in certain regions, making it a potential danger to humans who may accidentally ingest its fruit.
