You have these strange questions in life
Have you ever had these strange questions in your life: Do men also grow "orange peel" tissue? Does eating cheese really give people nightmares? What happens if you accidentally swallow chewing gum? In response to these strange questions that often flash in people's minds, BBC Focus magazine has summarized and answered them for your reference. Maybe this can help you solve your early doubts.
1. If we all stayed at home all day, would the flu go away in the crowd?
A: Yes. This would theoretically create a global immune system, but if one person walks out, the germs would spread immediately.
2. If chewing gum is accidentally swallowed, is it really indigestible and will remain for years?
Answer: No. Chewing gum is indeed difficult to digest, but it still cannot escape the normal human digestive system and will be digested in about three days at most.
3. What is the abbreviation for the word OK?
A. The most common belief that OK comes from the misspelled phrase "oll korrect," which means "all correct." It originated in Boston newspapers in the 1840s, when it was very popular to use deliberately misspelled words for humorous effect.
4. Can fish be allowed to live out of water?
Answer: Yes. There are many species of amphibian fish in the world. Likewise, there are about 50 species of flying fish.
5. Do some plants age and die?
Answer: Some plants can live forever if they maintain a good living environment and conditions. But once the external environment changes, their lifespan will end.
6. Is the marine climate good for the human body?
A. Not really. The upbeat smell of the sea breeze is due to a chemical product of coastal bacteria, even though it is present in small amounts in the air. But recent studies have shown that salt in the sea reacts with these chemicals to release harmful gases that pollute the air in the harbor.
7. Is talking to yourself a sign of madness?
A: No. Whether people are stressed or alone, talking to themselves is normal behavior.
8. Do men also have "orange peel" tissue?
Answer: Yes. It's not just women who worry about these pesky orange peel fats. Men have them too, and they're distributed in different parts of the body, like the neck or belly.
9. Where does fear really come from?
A. About 10 percent of people experience a constant internal fear. Some can cause physical problems, some can even lead to trauma. Studies have shown that simple phobias may be genetic, while others are cultural and historical. For example, the fear of spiders originated in the Middle Ages, when spiders were thought to be associated with plagues.
10. Can digital snapshots be preserved for a long time?
Answer: Yes. As long as you print them out and store them away from light or on a disc.
11. Can bacteria live on bacteria?
Answer: Of course. Small bacteria will parasitize large bacteria and attack them.
12. Why is sitting in the back seat of a car more prone to motion sickness and discomfort?
A. That may be because you can't get a good view in the back seat. Motion sickness is more likely when the balance organs in your ears are adjusting to a movement, but your eyes don't have enough vision to tell whether you're moving or stationary.
13. Can we survive with just water and simple supplies?
Answer: No. Carbohydrates, vitamins, minerals, fats and proteins are indispensable. They are not only used to supplement the energy required for life but also play an important role in the repair of cells.
14. Can hot drinks keep us cold?
Answer: Yes. Hot drinks make our bodies feel warm, but we don't actually get the same amount of calories. The satisfaction of this warmth causes our heat loss to accelerate.
15. Does the size of the head determine the level of intelligence?
Answer: No. Research shows that head size is at most only related to brain size, not IQ.
16. Does eating too much cheese give people nightmares?
A: Studies have shown that high-energy eating before bed reduces the duration of rapid-eye-movement sleep (REM), which can lead to dreaminess. But there are no clear results on how cheese affects sleep, dreams, or even the content of dreams.
