Dopamine, a neurotransmitter released during the beginning stage of a relationship, is also triggered when cocaine and nicotine are used. It provides the surge of pleasure and euphoria that makes those narcotics so addictive. It also increases the secretion of testosterone, which, as previously indicated, is necessary for attraction. If you were to choose between the three, we believe falling in love is the safer option.

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.

According to recent study from the University of Bristol, just 0.006 percent of the Korean population carries the ABCC11 gene. This gene is responsible for armpit odour. In fact, the study discovered that most East Asians lack this gene, with Koreans having the lowest amounts. While this may come as a surprise to Americans, it isn't a significant deal in Korea because deodorant isn't widely available!

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.

According to the World Health Organization, only Belarus consumes more alcohol than Moldova. With each person consuming an average of 16.8 litres of liquor each year (excluding under 15s). Well that is a lot of booze..

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.

Women, believe it or not, are more vulnerable to liver disease such as hepatitis (an inflammation of the liver) and are more likely to die from liver cirrhosis (a chronic disease).

Speaking of astronauts, their experience has shown that transitioning from weightlessness to gravity can be taxing on the body. Muscles atrophy and bones lose bone mass in the absence of gravity. According to NASA, astronauts in space can lose 1% of their bone mass per month.

Those enormous Stetsons you associate with cowboys like John Wayne, Billy the Kid, and Wyatt Earp? Yeah. Those were not worn by cowboys. In reality, the headgear of choice for nineteenth-century cowboys was a bowler hat.

Examine the yellow block above for a long time. Is it dizzying after a while? Perhaps even nauseous? If this is the case, you are not alone. A number of studies have found that the colour yellow can make people feel dizzy and nauseated. As a result, it is frequently used sparingly (or very strategically) by those in advertising and is almost never used in the interiors of various modes of transportation, most notably aeroplanes.

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.

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.

You might have already noticed that every picture of iPhones on any advertisement has the time set at 9:41. But why is that? There is a cool story behind this. When Steve Jobs announced the first iPhone, the local time was 9:42 at that time in San Francisco, California. They knew that they will unveil the iPhone at 9:42 and set the time to 9:42 in the slideshow as well.

However, when the iPad was released, they announced it at 9:41. Since then, this is still in effect as of yet. So, whenever you see an iPhone in any advertisement, you will see the time is set at 9:41. And, it is not a coincidence at all. Now you know the story behind this as well.

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."

Martin Lotze, a German researcher, studied the brains of both professional athletes and professional writers and discovered that their brain activity during athletic competition and the writing process was very similar. Lotze discovered an interesting difference between professional and amateur writers: professional writers used their speech-processing centres of the brain to develop their stories, whereas amateur writers relied on their vision centres to imagine the story first.

Robin Dunbar, a psychologist and the director of Oxford University's Social and Evolutionary Neuroscience research department, believes that every guy should spend at least two hours a week with 4-5 buddies. They can use this time any way they choose, from sports to going to bars. According to Dunbar, guys with faithful friends are less likely to be sad and have a better immune system.

Another fascinating Russian truth is that Russians learn not to grin as they get older. While many cultures consider smiling to be a sign of happiness and friendliness, Russians do not. Smiling, according to Russians, is a sign of weakness and not expressing one's actual sentiments. Russians grin when they see individuals they know and care about, but not when they see strangers, as many other cultures do. If you smile at a Russian on the street, don't expect them to reciprocate the favour; nevertheless, while driving around Russia, we noticed that many Russians smiled and waved back.

According to a 2013 research published in PLOS One, a sneeze moves at a pace of around 10 mph. Nonetheless, cover your mouth and nose to protect others from germs.

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.

Now, before you start freaking out, please hear us out! Sedentism is encouraged in today's environment. After all, we sit during our commutes, to eat, to watch TV, to work, to socialise with our friends, and so on. It turns out that even if you exercise regularly, it won't keep you safe from the risks of the "office lifestyle."

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.
