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.

Katie Mulcahey, a New Yorker, was jailed in 1908 for striking a match on a wall and lighting a cigarette with it. Why? Because it was a breach of The Sullivan Ordinance, a local ordinance that prohibits women (and only women!) from smoking in public. Mulcahey protested for her right to smoke cigarettes in public at her hearing in district court. She received a $5.00 fine. The Sullivan Ordinance was vetoed by New York City's mayor two weeks later.

In the second millennium BC, ancient Egyptians described hysteria for the first time. The term 'hysteria' was coined by Hippocrates from the Greek adjective hysterikos, which means "from the womb." He blamed hysteria on the womb wandering within the female body, which caused anxiety, tremors, convulsions, paralysis, and a sense of suffocation. Hysteria was first associated with the brain in the 18th century, rather than the uterus. According to Sigmund Freud, it is caused by trauma and can affect both sexes. The DSM did not remove the concept of hysterical neurosis until 1980. Dissociative disorders are now thought to cause hysterical symptoms.

To obey authority figures, people will go to great, and sometimes dangerous, lengths. Stanley Milgram, a psychologist, discovered in his famous obedience experiments that people would be willing to deliver a potentially fatal electrical shock to another person if the experimenters ordered them to.

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!

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.

Traditionally, Russia was Moldova's largest export market, consuming up to 90% of its wine. However, a diplomatic conflict in 2006 resulted in a Russian ban on Moldovan and Georgian products, which has proved disastrous to the economies of both countries. Nonetheless, it is the world's 20th largest wine-producing country (as of 2014).

Men have selective hearing, it's a fact! They can only listen to their female partners for 6 minutes, but this time is more than doubled to 15 minutes when they talk to their male friends. Before you start blaming men for their lack of attention, keep in mind that women pay more attention to conversations with their friends than to conversations with their romantic partners.

The date of February 14 was formally named "St. Valentine's Day" by Roman Pope Gelasius around the end of the fifth century. However, it wasn't until the Middle Ages that the festival became connected with love and passion, a tradition that sprang from the widespread belief in France and England that birds began their mating season on February 14.

A girl's brain is busy developing fine motor skills, verbal skills, and social skills in her first five years of life, all of which are highly valued by parents and teachers. Meanwhile, a boy's brain is hard at work developing gross motor, spatial, and visual skills. All of these abilities are useful for hunting. As a result, when it comes to learning and fitting in, boys frequently start school at a distinct disadvantage.

Apple actually approached Verizon to collaborate in the making of the iPhone. However, Verizon had some conditions that were not liked by Apple. Thus they reached out to ‘Cingular Wireless’(AT&T Mobility)with the proposal. And, both parties agreed to all the terms and conditions and started to work on the project secretively. After working for over 2 and a half years, Apple unveiled the iPhone. The estimated development cost of the iPhone was about 150 million USD.

According to research, the average attention span has shrunk by 12 minutes in the last decade. Human attention spans are now shorter than those of goldfish. Some research has even found a link between device multitasking — such as scrolling through social media while watching TV — and declining attention spans.

Your brain is working on problem solving and learning skills while you sleep. If you're learning a new skill or studying new information, getting enough sleep and having dreams can help you learn faster.

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).

When kissing, 70% of individuals turn their heads to the right. A German scientist who was monitoring kissing couples in airports, train stations, and beaches came to this conclusion. Perhaps this head posture is related to being right-handed.

Queen Elizabeth I used to use ceruse, a combination of white lead and vinegar, to paint her face. Despite how appealing these two components appear, you'll be surprised to learn that they are incredibly corrosive and ageing. "Those ladies that use it on their faces, do rapidly become withered and grey haired, for this doth so terribly dry up the naturall moisture of their flesh," one of her contemporaries observed of women who used ceruse. That sounds like a fantastic concept!

Ventriloquist dummies, like dolls, have become a staple of horror films. A ventriloquist's dummy named Slappy is one of R.L. Stine's most iconic antagonists. If they terrify you, avoid visiting the Ven Haven Museum near Fort Mitchell, Kentucky. Vintage ventriloquist dummies line the walls. This is undoubtedly your worst nightmare if you're afraid of dolls. How funny, these people should have destroyed them, but no, they thought why not show it to the world...

Start counting those sheep, since sleep is crucial. Many of history's worst tragedies, such as Chernobyl, Three Mile Island, the Challenger explosion, and the Exxon Valdez oil leak, were caused by a lack of sleep.

The ability to forget is a sign of high intelligence. According to scientists, forgetting is equally important as remembering. "Bad memory" is a mechanism in your brain that allows you to make more room in your brain for more relevant information. It also prevents your brain from squandering space and energy.

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..
