Wearing a tie can reduce blood flow to the brain by 7.5 per cent. A study in 2018 found that wearing a necktie can reduce the blood flow to your brain by up to 7.5 per cent, which can make you feel dizzy, and nauSEOus, and cause headaches. They can also increase the pressure in your eyes if on too tight and are great at carrying germs.
100 Mind-Blowing Flow Facts
Wearing a necktie could reduce blood flow to your brain by up to 7.5 per cent.
There were active volcanoes on the moon when dinosaurs were alive. Most of the volcanoes probably stopped erupting about a billion years ago, but NASA findings have suggested there might still have been active lava flow 100 million years ago when dinosaurs were still roaming.
People are more creative in the shower. When we take a warm shower, we experience an increased dopamine flow that makes us more creative.
The Kingsman underwater scene was not scripted. One of the most gruelling scenes in Kingsman is the underwater escape scene. The actors delivered a scene that even had you panicking. However, it’s closer to life than you think. The flooding was a technical mishap that derailed the rehearsed flow of the scene. Director Matthew Vaughn recalls it as a horrible first day of filming. The cut was still used in the film.
The world’s largest single-drop waterfall is the Kaieteur Falls. This is located on the Potaro River in the centre of Guyana’s rainforest. The average flow rate of the waterfall is 663 cubic meters per second.
We are more creative in the shower. Here’s one of the most useful weird fun facts! If you’ve ever felt like you think better in a warm shower, you’re probably right! The warm water increases the flow of dopamine and makes us more creative.
Wearing a tie can reduce blood flow to the brain by 7.5%. According to a 2018 study, in addition to increasing eye pressure and carrying germs, wearing a tie too tightly can make you feel nauSEOus and dizzy, as well as cause headaches.
We are more creative in the shower. Warm water in the shower increases the flow of dopamine and increases creativity.
During the hot summer, our nails grow faster. This weird fact about the human body is because of the increased blood flow to our fingertips.
If you wear a tie, it can reduce the blood flow to your brain by 7.5 per cent. Wearing a tie too tight can cause dizziness and headaches, including more pressure on your eyes.
Earth has a squishy interior. Earth’s interior is not solid but rather has a semi-solid or ‘squishy’ consistency owing to high temperatures and pressures. This squishy consistency allows the mantle to flow and move over geological timescales, which is responsible for phenomena such as plate tectonics, volcanic activity and Earthquakes. One consequence of this squishy interior is a process known as post-glacial rebound. During the last ice age, large portions of Earth’s surface were covered by glaciers, causing the underlying mantle to deform and sink. As the glaciers melted and receded, the mantle slowly rebounded back to its original position over thousands of years, causing the land above it to rise. This process is still occurring today in places such as Canada, Scandinavia, and Greenland, where the land is still rebounding from the weight of the glaciers that once covered the region. Recent research has found that West Antarctica is rising faster than anywhere else in the world, thanks to data from ESA’s GOCE gravity mission. The study of post-glacial rebound provides important insights into the structure and behaviour of Earth’s interior, and how it responds to changes in the surface environment over long timescales.
Earth’s magnetic pole is creeping westward. Unlike our geographic North Pole, which is in a fixed location, Earth’s magnetic north wanders. Until the early 1990s, the magnetic North Pole was known to lie some 1600 km south of true north, in Canada. Yet scientists realised that the location of the magnetic north wasn’t fixed and was drifting at a rate of 15 km a year. Since the 1990s, however, the drift of Earth’s magnetic pole has turned into more of a sprint. Its present speed is around 50-60 km a year and is making a dash towards Siberia at a pace not seen before. Why? Scientists studying the drift of Earth’s magnetic north pole, using data from ESA’s Swarm mission, have pinpointed a change in the circulation pattern of magnetic blobs deep below Earth’s surface. They learned a change in the flow underneath Canada has caused a patch of magnetic field at the edge of Earth’s core, deep within the Earth, to be stretched out. This has weakened the Canadian patch and resulted in the pole shifting towards Siberia.
There aren’t “57 varieties” of Heinz ketchup, and never were. Company founder H.J. Heinz thought his product should have a number, and he liked 57. Hint: Hit the glass bottle on the “57,” not the bottom, to get the ketchup to flow.
The two tiny holes in every BIC pen ensure that the air pressure is the same both inside and outside the pen, which helps the ink flow to the tip.
Throughout history, different cultures around the world have experienced time in different ways. In the Western world, we tend to think of time as linear and flowing from left to right. But this isn’t the case for everyone. Language affects how people conceptualize time, particularly the spatial metaphors they use to describe and map it. Those who read languages that flow from right to left, such as Arabic and Hebrew, generally view time as flowing in the same direction. The Aymara, who live in the Andes Mountains in South America, consider the future to be behind them, while the past is ahead. In their view, because the future is unknown, it’s behind you, where you can’t see it. Some Indigenous Australian cultures, which rely heavily on direction terms like north, south, east, and west in their languages, visualise the passage of time as moving from east to west. If they’re facing north, for example, the past would be to their right, or east, whereas the future would be to their left, which would be west.
