In the third episode of a question and answer series, the host answers several interesting questions. Ángel Murillo asks why we close our eyes when we sneeze. The host explains that sneezing is a natural defense mechanism that serves to expel germs and bacteria. It is difficult to keep your eyes open while sneezing due to the activation of nerves that control your eyes and nose. However, it is not impossible for some people to do it. The myth that sneezing with eyes open could cause your eyes to come out of their sockets is debunked, as it would require very intense pressure.
Miley Nahyan asks what planet we could live on if the Earth were destroyed. The host suggests that we could potentially live on Mars, which has frozen water at its poles, or on Venus, despite its extreme temperature. Human beings could potentially live in floating cities on Venus, where the gravity and temperature are almost identical to those of the Earth.
Pedro Suárez asks if the size of the countries that we see on the maps is correct. The host explains that maps are based on a specific projection to help ships navigate. However, this projection can distort the real size of the countries and continents. The Fuller projection accurately shows the extent of the countries and continents.
Arianna asks what is the animal that can live the longest in theory. The host explains that the Antarctic sponge can live up to 1500 years, but the Icelandic clam can live more than 400 years.
Daniel Maldonado Domínguez asks if it is true that house flies live only one day. The host explains that house flies go through a complete metamorphosis throughout their life cycle, from egg to larva, to pupa, to adult fly, and then they live as flies for about 15 to 25 days.
Katia Ramírez asks why sleeping a lot makes us more tired. The host explains that sleeping too much can confuse the body's cells and create a feeling of tiredness.
Mike. Pérez asks if it is true that when you die you go to the bathroom. The host explains that when we die, all the muscles in our body, including the intestines and sphincter, relax and it is common for corpses to expel waste that was inside the body before dying.
The host ends the episode with a discussion about tears, explaining why they have a salty taste due to the high salt content in our body.
1. The video is the third episode of a series where the host answers interesting and curious questions from the previous episode.
2. Ángel Murillo asks why when you sneeze you close your eyes. The host explains that sneezing is a natural defense mechanism to expel germs and bacteria from our body.
3. The host debunks the myth that sneezing with your eyes open could cause your eyes to come out of their sockets. This is because the pressure required for the eyes to come out of their sockets is very intense and is impossible to produce through sneezing.
4. Miley Nahyan asks what planet we could live on if the Earth were destroyed. The host suggests that Mars and Venus are possible options due to their potential for life.
5. Pedro Suárez asks about the size of the countries as depicted on maps. The host explains that the maps we commonly use are based on a type of projection that distorts the real size of the countries and continents.
6. Arianna asks which animal can live the longest in theory. The host mentions the Antarctic sponge and the Icelandic clam as potential contenders.
7. Daniel Maldonado Domínguez asks if it's true that house flies only live one day, despite being worldwide. The host explains that a house fly goes through a complete metamorphosis throughout its life cycle, with the adult stage lasting about a month.
8. Katia Ramírez asks why sleeping a lot makes us more tired. The host explains that sleeping too much can confuse the body's cells, leading to a feeling of tiredness.
9. Mike. Pérez asks if it's true that when you die you go to the bathroom. The host explains that after death, the muscles in our body relax and it is common for corpses to expel waste from the body.
10. The host explains why tears are salty, stating that our body is composed of a large amount of salt, which makes fluids such as sweat, urine, and tears salty.
