CULTURAL QA 05-2023-05 BY Mr G AND ERROR MODIFICATION BY KR IRS 6523 Q1 What are the most mind-blowing facts about the human brain?
KR: Repeated Q and my Repeated Q: Where is Hindustan? G The human brain is the only object of any kind that can contemplate itself. KR: How the brain would contemplate by itself sir? G Sixty percent of the human brain is made of fat. That make it the fattiest organ in the human body. KR: The brain is an organ with no actual muscle except for the muscle tissue in the middle layer of the arteries that carry blood to the brain. While the brain may not be a muscle, as many believe, you still need to exercise it — and the rest of your body — to keep it healthy and functioning at its best. The brain is an organ, and a very unusual and complex one at that. It plays a role in every one of our functions, controlling many organs, our thoughts, memory, speech, and movements. At birth, the average brain weighs 1 pound and increases to approximately 3 pounds by adulthood. The majority of that weight — 85 percent of it — is the cerebrum, which is divided in two halves. Your brain <https://www.healthline.com/health/your-brain-and-you> also contains cells, nerve fibres, arteries, and arterioles. It *also *contains fat and is the fattiest organ in the body — nearly 60 percent fat. (1.8 Lbs); {what is meant by the fattiest organ? Not weight sir; fat content is an organ formation; that is why in accidents brain is smashed lie potatoes; by weight its nothing: Liver normal may weigh 3 lbs; enlarged liver is much more; women 2 breasts would weigh 3% of the total body weight vis say 60 kg a women weigh breast may be 1.8 Kg or 4 LBS.} Exercising your brain using cognitive training tools, which are also called brain training games or brain exercises, may help improve your cognitive functioning. {KR It cannot meditate by itself.} Some studies have found that brain exercises improve memory <https://www.healthline.com/nutrition/ways-to-improve-memory>, executive functions, and processing speeds, while others have shown little to no effect. The impact of brain exercises may have something to do with age. Some studies have shown an improvement in cognitive abilities in young people and older adults. Brain exercises may also be beneficial in slowing age-related changes in the brain and those associated with neurological conditions, such as Alzheimer’s disease <https://www.healthline.com/health/alzheimers-disease> and dementia <https://www.healthline.com/health/dementia>. A study published in 2017 showed that a brain-training intervention known as “speed-of-processing training” significantly reduced dementia risk. If you’re looking to exercise your brain, you don’t necessarily need to resort to brain training games and apps. There is evidence that regular stimulation that comes from engaging in artistic activities such as painting and sewing, listening to music, and even socializing have been shown to improve and preserve cognitive function G The brain does not have pain receptors, so it cannot feel exterior pain. KR: The answer should have been better; fatty contents do not feel the pain as it has no receptors. The diabetic neuropathy feet do not know the pain as the receptor to reflect the feeling is dead or incapacitated. So too the brain. No use of harping to Sekar about me. Because simply like parrot throwing the cards by pulling, the brain receptors of Mr G did not function. Neurosurgeons are able to operate for 6 hrs continuously only because of that non-feel in that area. Or otherwise, pain receptors are placed in proximity to that area. It is like a loudspeaker cannot make any sound by itself. There are no pain receptors in the brain itself. But he meninges (coverings around the brain), periosteum (coverings on the bones), and the scalp all have pain receptors. Surgery can be done on the brain and technically the brain does not feel that pain. With that said, the brain is the tool we use to detect pain. Let’s say you’re on the beach and you step on a sharp shell. Special pain receptors in your skin activate whenever there has been an injury, or even a potential injury, such as breaking the skin or causing a large indentation. Now, an impulse is heading through the nerve into the spinal cord, and eventually all the way to your brain. This happens within fractions of a second. Your spinal cord is a complex array of nerves, transmitting all kinds of signals to and from the brain at any given time. The spinal cord is also in charge of your reflexes. The brain does not have to tell your foot to move away from the shell, because the spinal cord has already sent that message. The pain signal continues to the brain. This is because pain involves more than a simple stimulus and response. Your brain needs to make sense of what has happened. Pain gets catalogued in your brain’s library, and emotions become associated with stepping on that shell. When the pain signal reaches the brain it goes to the thalamus, which directs it to a few different areas for interpretations. Some areas in the cortex figure out where the pain came from and compare it to other kinds of pain with which is it familiar. Was it sharp? Did it hurt more than stepping on a tack? Have you ever stepped on a shell before, and if so was more or less painful? Signals are also sent from the thalamus to the limbic system, which is the emotional center of the brain. Feelings are associated with every sensation you encounter, and each feeling generates a response. For example, your heart rate may increase, and you may break out into a sweat. G Your brain has an autopilot setting allows us to perform common tasks like driving without actively thinking about them. KR: The problem of Mr G is, making an illiterate feel as if so, simple viz that is all. AUTOPILOT is not like autopilot in planes. Autopilot means doing the same thing in LOOP, as we hear music repeat. Many why all 100% would be looping some kind of thought, music, words etc unaware in their sub-conscious stage. That looping is autopilot. And that is the space of few seconds, when there is no other, MIND PROCESS. While looping thus, in the next 30th second, you want to know what happened to that? Q being answered; and immediate the autopilot loop is cut. Hence the science world thinks that few seconds, in immersed CAVING IN OR LOOP IS YOUR WELL BEING INTO THE CONSCIOUSNESS OR IN VEDIC WORD THE BRAHMAM; IMMEDIATELY ONCE ANOTHER THOUGHT CUT ACROSS, YOUR SUBCONSCIOUS STATE IS WIOED OUT. Many people stubbornly cling to the old distinction between the instinctive unconscious and rational consciousness, with a preference for the latter. But, as I have shown, this view is untenable. Unconscious processes greatly control our consciousness. Where you direct your attention, what you remember and the ideas you have, what you filter out from the flood of stimuli that bombard you, how you interpret them and what goals you pursue—all these result from automatic processes. Timothy Wilson of the University of Virginia considers this reliance on the unconscious to be the price that we pay for survival as a species. If we were forced always to consider every aspect of the situation around us and had to weigh all our options about what to do, humankind would have died out long ago. The autopilot in our brain—not consciousness—makes us what we are. Q4 What are some mind-blowing facts about Pakistan? G Sure, here are some mind-blowing facts about Pakistan: KR: Sure, really mind out flowing!! G Pakistan has the world's second-highest mountain peak, K2, which is also known as the Savage Mountain. KR Why I call G a liar?. *K2*, Chinese *Qogir Feng*, also called *Mount Godwin Austen*, called locally *Dapsang* or *Chogori*, the world’s second highest peak (28,251 feet [8,611 metres]), second only to Mount Everest <https://www.britannica.com/place/Mount-Everest>. K2 is located in the Karakoram Range <https://www.britannica.com/place/Karakoram-Range> and lies partly in a Chinese-administered enclave of the Kashmir <https://www.britannica.com/place/Kashmir-region-Indian-subcontinent> region within the Uygur Autonomous <https://www.merriam-webster.com/dictionary/Autonomous> Region of Xinjiang <https://www.britannica.com/place/Xinjiang>, China <https://www.britannica.com/place/China>, and partly in the Gilgit-Baltistan portion of Kashmir under the administration of Pakistan <https://www.britannica.com/place/Pakistan>. [image: K2] <https://cdn.britannica.com/16/176816-050-1B617971.jpg> K2 <https://cdn.britannica.com/16/176816-050-1B617971.jpg> The glacier- and snow-covered mountain <https://www.britannica.com/science/mountain-landform> rises from its base at about 15,000 feet (4,570 metres) on the Godwin Austen Glacier, a tributary of the Baltoro Glacier. The mountain was discovered in 1856 by Col. T.G. Montgomerie of the Survey of India, and it was given the symbol K2 because it was the second peak measured in the Karakoram Range. The name Mount Godwin Austen is for the peak’s first surveyor, Col. H.H. Godwin Austen, a 19th-century English geographer. KR Is it only Pakistan mind or China too mind? See map above. G The world's largest deep seaport, Gwadar Port, is in Pakistan's southwestern province of Baluchistan. KR The *Gwadar* Port ( Urdu: گوادر بندرگاہ [ˈɡwaːdəɾ ˈbəndəɾɡaː]) is situated on the Arabian Sea at Gwadar in Baluchistan province of Pakistan and is under the administrative control of the Maritime Secretary of Pakistan and operational control of the China Overseas Port Holding Company. Calling itself as the largest is dubious since in the world Malacca like deep seaports, may be bigger than this also. Not confirmed as such. G Pakistan is home to the Harappa and Mohenjo-Daro civilizations, which are among the world's earliest human settlements. KR who is this Zakir Hussain @ Goebel? After the division of Pakistan, it is in the Pakistan; so it is not revealing Muslim culture. Epporul yar vayk ketpinum apporul meipporul kanbadu arivu; and G does not like Tamil and knows nothing in Malayalam also; or else wont be cautious to handle a Muslim write up conch blowing? G The world's largest irrigation system, the Indus Basin Irrigation System, is in Pakistan and supports the country's agriculture. KR *Great Man-Made River (GMR)*, vast <https://www.britannica.com/dictionary/vast> network of underground pipelines <https://www.britannica.com/technology/pipeline-technology> and aqueducts <https://www.britannica.com/technology/aqueduct-engineering> bringing high-quality fresh water <https://www.britannica.com/science/water> from ancient underground aquifers <https://www.britannica.com/science/aquifer> deep in the Sahara <https://www.britannica.com/place/Sahara-desert-Africa> to the coast of Libya <https://www.britannica.com/place/Libya> for domestic use, agriculture, and industry. The GMR has been described as the largest irrigation <https://www.britannica.com/technology/irrigation> project in the world. (Indeed, the Libyan government proudly proclaimed it “the Eighth Wonder of the World.”) Since 1991 the project has supplied much-needed irrigation and drinking water to populous cities and farming areas in Libya’s north, which previously were dependent on desalination <https://www.britannica.com/technology/desalination> plants and on declining rain-fed aquifers <https://www.britannica.com/science/aquifer> near the coast. G Pakistan is the only Muslim country to have achieved nuclear power status. KR I need not answer but all of you pl check G The Khyber Pass, a historic mountain pass that connects Pakistan with Afghanistan, has been a key trade route for centuries. KR It was when the Bharatha varsha was; today it is illegal soldier by pass road. G 13. Pakistan's military strength is ranked as the seventh strongest in the world according to the Global Firepower Index 2023. The country has a large standing army, air force, and navy, as well as a growing nuclear capability. Pakistan also has a robust defence industry and has been able to develop and produce its own military hardware, including fighter jets, tanks, and missiles. KR: G is hired by any ISIS? Pakistan Army surpasses Israel, Canada to become 10th most powerful in world. India can wipe out overnight. G 14. Pakistan is known for its rich spiritual heritage and is home to many famous Sufi saints, including Saint Shahbaz Qalandar from the 12th century and Saint Shah Sadaruddin Lakyari from the 11th century. The saints taught about love, tolerance, and spiritual devotion and continue to inspire people from all over the sub-continent. KR A way out to think. All India records since Dayan Chand to Qalandar nor branded das Pakistan well. Q9 Why do not crocodile attack hippos? KR Parroting again Q10 What are some of the most mind-blowing facts? A10 Hafiz Suboor, Mar 26 The Nazis were the first ever people in modern history to start an anti-smoking and tobacco movement. KR NO NOT AGAIN and I had answered already There are at least six people in the world who look exactly like you. There is a 9% chance that you will meet one of them in your lifetime. KR OMG again In a survival situation, if you were to drink seawater, it would rapidly dehydrate you and soon lead to your death. However, it is vastly less harmful to eat frozen seawater. This is because it has a tenth of the amount of salt in its liquid form since the salt is separated from the water when freezing as it does not fit into the crystalline structure of ice. KR oMG again If a part of your body “falls asleep,” you can always “wake it up” by shaking your head. KR again and again The reason the taste of artificial banana flavouring, and artificial banana flavoured products does not taste like bananas is that it is based on a type of banana that was wiped out by a plague in the 1950s. KR oops Your shoes are the first thing people subconsciously notice about you. Wear nice shoes. KR How many times? Viagra, when dissolved in water, can make cut flowers stay erect for up to a week longer than they usually would. Try it! KR Repeat again? There are three things the human brain cannot resist noticing – Food, attractive people, and danger. KR Cant find more words to say repeat so hereafter only ??/ The word “quarantine” derives from the Venetian dialect of Italian and the words “quaranta giorni,” meaning “forty days.” This is because when it was discovered that ships were infested with plague-carrying rats, they were made to sit at anchor outside Venice’s city walls for forty days before coming ashore. KR ???/ You can survive without eating for weeks, but you will only live 11 days without sleeping. KR ???? Laziness and inactivity kill just as many people as smoking. Kr ???? About 1 percent of people alive today are descended from Genghis Khan. KR Another Goebel on the rise? G If you folded a piece of paper forty-two times, it would be thick enough to reach the moon. KR If anyone interested to know the correct answer, please read this which you or no one can fold like that. “Assume the thickness of the paper is 0.1 mm. Then the thickness of the paper folded 42 times is as follows. 439,804,651,110.4mm is about* 439,000 km*. The distance from the Earth to the Moon is about 380,000 km. So, if you fold a paper 42 times, it really reaches the moon.” The human nose can detect more than one trillion smells. KR ???? In China, in 2013, scientists were able to grow a human tooth from scratch using stem cells taken from urine. KR ??/? Your mouth produces about one litre of saliva a day. KR oops Nokia was originally founded in 1865 as a paper printing company. Apt to say, when it was founded, the paper was one of the world’s most used methods of long-distance communication!
