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.

You may or may not be aware that love can result in strong infatuation. The same serotonin levels reported in persons with obsessive-compulsive disorder, an anxiety disorder, are found in those with infatuation. This is most likely why you can't seem to think of anyone else while you're in love.

Dresses were worn by men from many cultures around the world. The Scottish kilt, for example, and the toga worn by the ancient Greeks were all examples of menswear. Dresses were only later appropriated by women, and men stopped wearing them.

Italy was a dictatorship until 1945, while having a royal dynasty until 1946. Following WWII, the country decided to become a republic, and King Umberto II governed briefly from May 9 to June 12, 1946. He spent the rest of his days in exile in Portugal. In Italy, he is regarded as "the May King," a reference to his exceptionally brief rule.

Do you consider all of your decisions, weighing all of your options and calculating the impact of each outcome? You may believe you are, but you are incorrect. The majority of your decisions are made subconsciously because your conscious mind would be overwhelmed with information and you would likely become mentally frozen. This is because your brain receives over 11 million bits of information every second, and there simply isn't enough "brainpower" to process it all consciously.

When explaining behaviour, we often attribute positive outcomes to internal factors and negative outcomes to external forces. When it comes to other people's actions, however, we usually attribute them to internal characteristics. For example, if we receive a poor grade on a paper, it is the fault of the teacher; if a classmate receives a poor grade, it is because he did not study diligently enough. The actor-observer bias refers to this tendency.

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.

Komorebi, for example, means "sunshine flowing through leaves." It's an odd term, but if you start learning Japanese, you'll discover many more. Furthermore, the harshest curses in Japanese are "fool" and "idiot." Another fascinating aspect is slang. For example, "gaijin" means "foreigner," "baka" means "fool," and "baka-gaijin" is slang for "American."

The United States government physically poisoned booze during Prohibition. When individuals continued to drink alcohol despite its prohibition, law enforcement authorities were dissatisfied and decided to try a different form of deterrent—death. They directed the poisoning of industrial alcohols made in the United States, which were frequently stolen by bootleggers. The federal poisoning operation is estimated to have killed at least 10,000 individuals by the end of Prohibition in 1933.

Scientists from the University of Birmingham investigated bikers aged 55 to 79 who ride their bikes for many hours each day. These researchers discovered that cycling in old age keeps muscle mass and strength from deteriorating. And the fat and cholesterol levels remained constant. However, the most incredible discovery is that cyclists' systems generate immunological T-cells in equal numbers to 20-year-olds. It's incredible since T-cell production begins to decline around the age of 20. This demonstrates that riding a bicycle makes the immune system younger.

Why doesn't your stomach digest itself if it has so many enzymes and acids that it can digest a piece of meat? It turns out that it sort of does. The cells that line your stomach proliferate fast in order to replace the cells that are killed in the course of their everyday tasks. Every three days, we develop a new gut lining.

It's extremely unusual, yet it has happened. The event known as "coffin birth" happens when a pregnant woman dies and her kid is born spontaneously owing to gases that build up in the abdominal area, placing pressure on the mother's uterus and driving the baby through the birth pathway. According to Smithsonian, one example of this was discovered in the grave of a mediaeval woman who was buried in Italy in 2010.

In terms of the most educated population, Ukraine ranks fourth in the world. 99.4% of Ukrainians aged 15 and up can read and write. 70% of adult Ukrainians have a secondary or higher level of education. Even Ukraine's current heavyweight champions, Vitali and Wladimir, have doctorates.

Unfortunately, Apple has officially announced that they will not share the iPhone sales figure anymore back on November 1, 2018. So, we actually don’t the current sales figures of the iPhone. However, we can tell you the number from 2007 to 2018, though. Reports say that Apple has sold over 2.3 billion units of iPhone in this period. And, they sold about 220 million iPhones in 2018 alone.

We frequently predict how we will react to a future event, only to find out that we reacted completely differently than we anticipated. We put our faith in the ability of a single event to change everything, but we frequently discover that it has little effect on how we feel.

Fetuses with short protuberances have been observed as early as 16 weeks of gestation. While there haven't been enough studies to determine why this happens, some point to the age-old "use it or lose it" theory—the Los Angeles Times reported that periodic movements are required to keep the penile tissue oxygenated and healthy.

According to University of California researchers, we spend 30% of our time daydreaming every day. This proportion can go as high as 70% at times (for example, during long travels), but there's nothing wrong with it. According to studies, those who enjoy floating in the clouds are more creative. They're also superior at problem-solving and stress relief.

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.

There is a lot of evidence that following a pattern for 66 days will make it habitual. If you want to be better at cleaning your house or going to the gym, make a concerted effort to do so for 66 days, after which it will become a habit and be easier to maintain (this also works for breaking habits).

You may have noticed that women take more risks than men, and there is a scientific reason for this. Women have a larger anterior cingulate cortex than men, which is the part of the brain that weighs options when making a decision. Some argue that this was evolution's way of making women better caregivers and saving the "tribe" when it came to gathering food and establishing social structures.

iPhone was released in the USA on 29 June 2007. At that time, 2 models of the iPhone were released. The difference between the two models was in the internal storage and the price. The 4 GB model was priced at $499 and the 8 GB model was priced at $599. Tens of thousands of people waited days before the launch for the iPhone in front of the AT&T and Apple retail stores for buying the iPhone. Matter of fact, lots of stores reported stock shortage within half an hour of the release.

Archaeologists uncovered a tablet in Iraq in 1976, which has since been lost. Researchers, on the other hand, were able to interpret and decipher the writing from an image of the tablet. What were the outcomes? We know the tablet contains jokes, but the complete context has been lost in translation. The world's oldest your mother joke is "...of your mother is by the one who has relations with her." "What or who is it?" Do we comprehend it? No way, but we know a "your mom" joke when we see one!

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.
