*CULTURAL QA 04-2023-20* Q2 What are some of the most mind-blowing facts?
Every time you blink, you miss out on 100 images that your brain could have processed. KR: First, light passes through the *cornea* (the clear front layer of the eye). The cornea is shaped like a dome and bends light to help the eye focus. Some of this light enters the eye through an opening called the * pupil *(PYOO-pul). The *iris* (the colored part of the eye) controls how much light the pupil lets in. Next, light passes through the *lens* (a clear inner part of the eye). The lens works together with the cornea to focus light correctly on the retina. When light hits the *retina* (a light-sensitive layer of tissue at the back of the eye), special cells called photoreceptors turn the light into electrical signals. These electrical signals travel from the retina through the *optic* *nerve* to the brain. Then the brain turns the signals into the images you see. Your eyes also need tears to work correctly. There are two main reasons, said Dr. Brenda Pagan-Duran, a clinical spokesperson for the American Academy of Ophthalmology and an ophthalmologist in New Jersey. First, blinking clears away particles from the eyes. "If there's a foreign body, it helps get rid of it," she told Live Science. "It might be under the eyelid or something that blew in." Second, blinking lubricates the eyeballs. The eyes need a smooth surface for light to properly focus on, so vision doesn't become blurry. Blinking releases a tear film — which mostly consists of water, oil and mucus — to keep the surface of the eyeball smooth. Sir now are the eyes efficient or you wany more images to be processed and lose the vision? An ant can lift up to 20 times its own body weight. KR: OUTMODED ANSWER. In the *Journal of Biomechanics*, researchers report that the neck joint of a common American field ant can withstand pressures up to 5,000 times the ant’s weight. “Ants are impressive mechanical systems—astounding, really,” said Carlos Castro, assistant professor of mechanical and aerospace engineering at The Ohio State University. “Before we started, we made a somewhat conservative estimate that they might withstand 1,000 times their weight, and it turned out to be much more.” Q6 What are some of the most mind-blowing facts? The Nazis were the first ever people in modern history to start an anti-smoking and tobacco movement. KR: YOU MAY HAVE TO RECHECK AS MOST GENERALS AND OFFICERS OF THE German army were smokers. And *The Health Consequences of Involuntary Exposure to Tobacco Smoke: A Report of the Surgeon General* (HHS, 2006) and the Institute of Medicine (IOM) report* Ending the Tobacco Problem: A Blueprint for the Nation* (IOM, 2007). DOES NOT SAY SO Your shoes are the first thing people subconsciously notice about you. Wear nice shoes. KR: Where in India sir? Viagra, when dissolved in water, can make cut flowers stay erect for up to a week longer than they usually would. Try it! KR Who said so? Wrong. There are three things the human brain cannot resist noticing – Food, attractive people and danger. KR: It is hasty generalisation Q8 What are some mind-blowing facts about countries? Iceland the only country in the world where mosquitoes don't exist. KR: Partly correct. Unfortunately, no one really lives in Antarctica, considered on average the coldest, driest and windiest continent <https://www.treehugger.com/windiest-places-world-4869343> on Earth. Though it lacks permanent residents, there are thousands of people who spend weeks or months in research stations in Antartica’s remote areas <https://www.treehugger.com/worlds-most-remote-communities-4869113> to study everything from the weather to the midges. But Iceland is free and people are living under minus 67 degrees going to school.
