According to research, our brain can only keep 3-4 pieces of information at a time. Furthermore, this data can only be saved for 20-30 seconds. We forget it after this period unless we keep renewing it in our minds over and again. For example, you are driving while chatting on the phone (do not do this!). The person on the other end of the line gives you a number, but you can't write it down, so you memorize it. You repeat the number several times to keep it in your short-term memory until you disconnect and write it down.

Seattle residents Peter Cicero and Richard Sclafani are credited with inventing the number-themed eyeglasses that are now seen at New Year's Eve parties around the world. According to the Wall Street Journal, their first set, which read "1991," sold 500 pairs. The following year, approximately 3000 sets were purchased.

Apple has various devices like iPad, iPod, Mac, watch, and more. However, the most popular of them all is the iPhone. They reported that they have got revenue of about 25.99 billion USD for Q3 2019 from the sales of the iPhone.

When you burp on Earth, gravity keeps the solids and liquids from the food you just ate at bay, allowing only the gas to leave your mouth. Because the gas cannot separate from the liquids and particles in the absence of gravity, burping effectively becomes vomit.

Walter Arnold of the English town of Paddock Wood, Kent, was the first person to be charged for speeding, according to Guinness World Records. On January 28, 1896, Arnold was caught driving four times the speed limit in his 19th-century Benz—but because the speed limit at the time was only two miles per hour, he wasn't travelling too fast by today's standards. The officer had to track him down on his bike, issuing a £4 7s penalty and earning Arnold the swift distinction.

If you want to do something creative, such as write a short story or design a dress, do it after a long and stressful day. This is because studies have shown that when people's brains aren't functioning as well as they should, they become more creative. This is one of the main reasons why people frequently come up with brilliant ideas while taking a shower after a long day at work.

Scientists can detect whether a gene has been effectively inserted into an animal's DNA by adding some type of clearly recognised marker to it. When testing an anti-FIV gene in 2011, scientists at the Mayo Clinic employed a fluorescent protein from a particular jellyfish. The tests were successful, however the cats did glow in the dark. In fact, these cats' offspring sparkle in the dark! Nonetheless, their accomplishment is only one step toward an ultimate solution for AIDS.

During the first year of being in a romance, a protein in our cells called Nerve Growth Factor (NGF) that is vital for the functions of particular sympathetic and sensory nerve cells, appears to thrive. During youthful love, our senses are heightened, and our fight or flight reaction system is activated.

There is a spa in Japan where you can bathe in coffee, as well as wine, tea, and other beverages! Bathing in coffee is said to have recharging, relaxing, and skin beautifying properties.

The amount of bourbon barrels in Kentucky outnumbers the state's population by more than two million. That's quite a bit of bourbon. Kentucky is the home of bourbon and produces 95 percent of the world's supply.

The "Pygmalion effect" or "Rosenthal effect" refers to the phenomenon that higher expectations can increase performance. Professor Robert Rosenthal was the first to demonstrate it. In a California elementary school, he conducted an experiment and discovered that when teachers are made aware of students who have a high chance of success, their expectations rise. As a result, they paid special attention to those students and sometimes treated them differently. Essentially, the teachers subconsciously acted differently toward those students, which promotes their success. This has a positive impact on the student, and their performance improves as a result.

It may be difficult to believe, but we have roughly the same number of hairs on our bodies as chimps; the difference is that our hairs are useless, being so fine that they are almost invisible. We're not sure why we lost our furry protection. It has been proposed that this was done to help early humans sweat more easily, to make life more difficult for parasites like lice and ticks, or even because our ancestors were partially aquatic.

Cheese rolling is one of the oddest sports that takes place every spring in Gloucestershire, in the west of England. An 8-pound round of Double Gloucester cheese is rolled from the top of Cooper Hill, and competitors pursue it down to the bottom. They are intended to catch the cheese, but it is nearly impossible, thus the first person to cross the finish line wins the cheese.

Wilbur and Orville Wright, popularly known as the Wright Brothers, are famed for inventing the aeroplane, which may lead you to assume they were a well-educated couple, however none of them graduated from college. The discovery gained the brothers fame and money, and thankfully for them, they did not live to become one of those innovators who regretted their creations.

The notion that Einstein struggled at school is a fiction. A pre-teen Einstein would study mathematics and physics for fun over the summers, finally mastering differential and integral calculus by the age of 15. But it doesn't mean he was a model student. Einstein despised rote learning and refused to study things that bore him. As a result, when the stubborn number-lover took the polytechnic school admission exam in Zurich, he flunked the language, zoology, and botany parts.

On Mondays, the chance of suffering a heart attack rises by 20% for men and 15% for women. It's most likely due to the stress of having to return to work. However, scientists caution that alcohol drank over the weekend can potentially be a cause of a heart attack.

Austrians celebrated their victory over Hungary during the 1848 revolution by clinking their drinks during a toast. Since then, Hungarians have avoided clinking their glasses while toasting since it reminds them of their loss. Instead, if you're drinking a beer in Hungary, say "Egészségedre" while looking your drinking companions in the eyes.

In the good ol' USA, around 300 billion pizzas are sold each year. Not only that, but 93 percent of Americans have eaten pizza in the last month, according to a recent survey. Around the Super Bowl, there is a significant increase in pizza delivery sales. It doesn't get any more American than that! Unfortunately, there is no official statistics on how many of those pies were devoured as a result of Amazon billionaire Jeff Bezos' "Two Pizza Rule."

Everyone has experienced the agony of rejection at some point in their lives, but did you know that rejection causes physical harm as well as emotional pain? Even if you are unable to feel physical pain, scientists have discovered that the reactions and cascading events that occur in the brain after rejection or physical pain are nearly identical. Furthermore, the same natural chemical is released in both cases.

You may have outgrown the hours-of-making-out-on-the-couch stage of your relationship, but you shouldn't dismiss kissing as a pleasurable pastime with your partner—and also a type of exercise! According to Woman's Day's sexologist, one hour of mild kissing burns 68 calories. "Oh my god, an hour?" you may be thinking. Yes, an entire hour. You've got this! You've always wanted to work out with your hubby, and now is your chance.

If you're familiar with Spider-Man, you'll know that one of his most potent talents is his renowned Spider Sense. This heightened sense had alerted him of impending threats and had saved his life several times. His spidey sense was always on and practically hard to avoid. It was unaffected by darkness or blindness. That alone makes it incredible, but it is far more potent than you may expect. It alerted him of existential hazards to his well-being in addition to acute bodily concerns. It would even warn him to any possible witnesses when he changed his outfit, for example.

Researchers at Arizona State University made the ground-breaking discovery that the ability to see red in all its glory is frequently gender-dependent. There is a gene that allows people to see and interpret red and its related colours such as cardinal, maroon, crimson, and so on, and that gene is linked to the x-chromosome. Because women are born with two x chromosomes, they have a better ability to see the entire red spectrum, whereas men, with a single x chromosome, aren't necessarily equipped to tell the difference between red and, say, cardinal.

If you don't like grapes, wearing crimson underwear on New Year's Eve is also said to bring good luck. The custom of wearing red underwear on December 31 is widespread, spanning Italy, Spain, Bolivia, and beyond. Everyone is welcome to take part; men and women alike follow the tradition. Participants also have a variety of clothing options as an added bonus. Others wear socks, bras, and garters, while some wear red boxers, briefs, or panties.

Tooth decay occurs when bacteria in your mouth convert sugar into acids, further eroding the tooth's surface and causing cavities. Cocoa beans contain antibacterial agents that inhibit the growth of these bacteria and help to prevent tooth decay. Dark chocolate contains more cocoa than milk chocolate. However, this does not imply that you consume chocolate on a daily basis.
