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.

If you're using romantic whispers to impress a potential partner, make sure to speak into his or her left ear. An MITCogNet study discovered that when emotion stimuli were delivered to the left ear, recall accuracy was more than 6% higher than when the same stimuli were delivered to the right ear.

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!

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.

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.

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...

This curiosity has a social explanation rather than a scientific one. For centuries, society and the media have pushed women to hold themselves to a certain standard, whether it's small feet or a perky behind, and the majority of women have chosen stylish presentation over comfort.

Guns and tiny toddlers are the ideal mix for having fun. A terrific location to take your kids, ages 12 to 18, that is completely safe. Simply purchase a ticket for them and they are set to enjoy their time at the military "Disney" camp. Despite the fact that this location is officially affiliated with Disney, the character of this "amusement park" is everything from childlike. Professionals teach children how to handle assault and sniper rifles and even introduce them to bare-handed fighting. Every day that they stay there, they practise their survival abilities, as the campers typically take on an obstacle course and form teams for sporting contests after breakfast.

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.

Einstein was leaving a ceremony in his honour on his 72nd birthday. Photographers begged him to grin for the camera as he was getting into his car. Einstein, on the other hand, was weary of smiling for photos—he'd be doing it all evening—so he stuck his tongue out instead. Einstein was so taken with the photograph that he had it printed as greeting cards.

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.

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). Women are also more likely to suffer from alcohol-related brain damage, such as loss of mental functions and reduced brain size.

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.
