Danish researchers investigated 387 pairs of twins in their 70s, 80s, and 90s. They discovered that merely glancing at someone’s face may predict whether they would live until old age. If a person appears younger than their actual age, they will live longer than if they appeared older. And scientists have showed that it is pre-programmed at the DNA level. Telomeres, which are key bits of DNA that signal a cell’s reproduction ability, are also connected to how youthful a person seems. People who appear to be younger have shorter telomeres, yet longer life...

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.

In the winter, street sellers offer ice cream from paper boxes on the street. At -30 degrees Celsius, there's no need for a freezer (-22 degrees Fahrenheit).

The Salem witch trials took place between February 1692 and May 1693 in Salem, Massachusetts. Nearly 200 individuals, including the destitute, the elderly, and a four-year-old kid, were accused of witchcraft. The vast majority were imprisoned, and some were executed by hanging. However, none of these people were ever burned alive.

When people meet for the first time, colour recognition accounts for the vast majority of their first impressions. According to studies, those who consistently wear neutral or black make fewer positive first impressions, whereas those who wear brighter colours are more likely to form friendly bonds. Wearing hints of red (for women) or blue (for men) on a first date may result in stronger feelings and a definite second date, whereas those who wear black to a job interview are more likely to be hired.

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.

When Chaim Weizmann, Israel's first president, died in 1952, the Prime Minister invited Einstein to fill the (mostly ceremonial) office. The scientist said no, writing: "I am extremely affected by our State of Israel's offer, and I am both heartbroken and humiliated that I cannot accept it. I've spent my whole life dealing with objective issues, therefore I lack both the natural ability and the expertise to deal with people and carry out official tasks."

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.

Asakusa is a must-see, with its charming streets (and even the metro station) adorned with these beautiful paintings depicting Japanese history. The thick but aesthetically unified murals exude a cultural vibe while fulfilling two functions: art and storytelling. In Asakusa, you can also buy unusual foods and souvenirs and watch cooks produce street delicacies via glass windows. Visit the iconic Kaminarimon temple, albeit you may have to compete with other eager tourists!

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.

During the Victorian era, there was a significant change in the way people dressed. The Victorian dress reform, also known as the rational dress movement, occurred between the 1860s and 1890s, during the middle and late Victorian eras. Reformers proposed, wore, and even designed clothing that was more practical and comfortable than what was available at the time.

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."

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.

Despite the fact that he is a fictitious character, Bruce Wayne has a higher IQ than Albert Einstein! Einstein's IQ was estimated to be between 160 and 180, while Bruce's is 192!

Scientists from Sydney's Garvan Institute of Medical Research discovered that shivering in the cold for 10 minutes burns more fat than a one-hour workout. These new discoveries build on a past study into brown fat, a kind of fat tissue that consumes energy rather than storing it. So Start shivering...

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.

Despite having one of Europe's oldest histories, Italy has only been a country since 1861. Italy was a unified entity throughout the Roman era. It was thereafter separated into independent states, which it remained until 1861. Because of this lengthy history of individualism, the country now has such a diverse spectrum of cultural variants.

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.

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...

This study was inspired by evidence obtained from wrongful conviction cases. The study involved interviewing adult suspects in a comfortable setting and employing poor memory retrieval techniques. Within three hours, the suspects had been interrogated in ways that led them to believe in and confess to crimes they had not committed. They were even able to vividly describe the events, and some of them believed they had committed a crime as serious as assault with a weapon as teenagers. Are you willing to be persuaded?

Though concluding definitively that colour affects a person's psyche has proven difficult, there have been a plethora of studies — some official, some not so official — that have come close. These investigations date back to the 1930s, when neurologist Kurt Goldstein began experimenting with colour and appearance. Goldstein discovered, for example, that people automatically assume red objects are heavier, while green objects are lighter.

In the 13th century, Pope Gregory IV waged war against cats. He said that black cats were Satan's tools. He commanded the annihilation of these felines throughout Europe as a result of this notion. This strategy, however, backfired, resulting in a rise in the number of plague-carrying rats.

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."

Boys, more than girls, are more likely than girls to learn many lessons through experience rather than being told. This can make parenting them difficult, especially if you don't enjoy taking risks yourself. The most difficult challenge may be keeping them safe, so some risks must be avoided. It can also be difficult to be a support person as a parent when the lessons that boys learn bring hardship and tears.
