The video is an episode from a series where the host answers intriguing, curious, and embarrassing questions. In this episode, they are discussing 10 questions at random, with future episodes taking questions from the comment box. The topics range from the science behind memory, the composition of clouds and water, how birds handle high voltage cables, the inflation of balloons underwater, the weight of the Earth, the effect of helium on voice pitch, the aging process of hair color, the spoilage of water, the largest tree in the world, and a chicken that lived without a head for over 18 months. The host encourages viewers to leave their questions in the comment box for future episodes.
1. This is a new series of express TV where they answer intriguing, curious, and embarrassing questions.
2. The first episode will take 10 random questions, while the following episodes will take questions from the comment box.
3. The series will address the phenomenon of infantile amnesia, where adults cannot remember anything from their first years of life.
4. Memory is divided into two parts: sensory memory and semantic memory. Sensory memory stores immediate memories, such as what you ate or wore.
5. Semantic memory is where the memories that we will never forget are stored.
6. The reason we forget our first years of life is because our brain is eliminating and creating large amounts of neurons during this age.
7. The largest tree on earth is a sequoia called General Hermann. It is characterized by growing between 50 and 85 meters high and measuring about 5 to 7 meters in diameter.
8. Chickens can live without a head for around 15 minutes. However, a chicken in Colorado, USA, managed to live for more than 18 months after being decapitated.
9. The clouds are made up of billions of frozen water particles so small that they float in the air thanks to the sun.
10. The Earth could weigh around 6,000,000,000,000,000,000 after many mathematical calculations.
11. Helium makes the voice sound higher in human beings.
12. The color of our hair and skin is determined by melanin. As we age, the pigment cells in our hair follicles progressively die, making our hair less and less colored.
13. Water does not spoil us, but it becomes contaminated when it is dirty. This is because of bacteria or chemicals.
14. Bottled water does not expire if the plastic base that contains it does not begin to release toxic substances that when mixed with the water will contaminate it.
15. Birds do not get electrocuted by high voltage cables. Electricity is weak and always looks for the easiest way to reach its destination. Since the metal wire is a much better conductor of electricity than the bird, almost all the current will take the path of the wire instead of wasting time in passing through the body of the bird.
