A series of 'sixth sense' hidden in humans

Call funny is the "6th sense", because this is a premonition to help people distinguish true smile - fake, sniffing potential enemy . that rarely pay attention to.

>>>The sixth sense has been very popular

Surely one of us once dreamed of being able to fly like a superman, reading other people's thoughts like Professor Xavier in the X-Men series or delighting in flying in mid-air like Spider-Man.

These esper powers seem to appear only in comic books or sci-fi movies. However, in fact, scientists have initially discovered special abilities that we do not know we still use every day.

Explore these super powers together by summarizing the Cracked page below.

1. Distinguish real-fake smiles

Does one of us have witnessed the person facing me trying to smile even though that smile is extremely awkward to please those around us? The reason is because of a true smile and a different artificial smile and our brain is able to recognize that difference.

To prove this hypothesis, a group of researchers in Bangkok (Thailand) conducted an experiment. They attached a series of sensors to the faces of the participants and let them talk to each other. The results show that true and artificial smiles are controlled by completely different muscles on the face.

Do you see the signs of this fake smile?

Specifically, a fake smile is created from the initiative, the conscious part of the brain will function strongly, controlling the cheek muscle that causes the cheeks to shrink.

In contrast, true smiles come from the unconscious part and are done automatically. When people feel comfortable, the signals will pass through the brain processing emotions. They cause the mouth muscles to move, the eye muscles and the eye part of the eye muscles to lift the cheekbones, making the eyes open, eyebrows raised a little.

Signs to recognize a true smile

So scientists think that each of us is basically a "psychic " in the field of smile discrimination. We can completely detect and smile back even before the opponent smiles really.

2. 'Sniffing' is potential enemy

The researchers discovered that the smell of a woman close to ovulation triggered an increase in testosterone levels in her partner's body that smelled it.

To test, scientists at the University of Florida studied testosterone levels in some women after letting them smell the T-shirts of other women (including those in different periods of ovulation ).

The results showed that their testosterone levels would increase when smelling the clothes of women who are in ovulation.

Testosterone is a predominant hormone in men, if the concentration of this hormone increases, the subject will get angry and react excessively in some cases, even clashing with others.

This explains why women tend to be competitive, aggressive when "sniffing" to see another woman during ovulation.

3. Detecting men cheating by just watching

Research by experts at the University of Western Australia indicates that women can detect men lying only by glancing at them. To demonstrate this research, experts have conducted an experiment on the topic of sincerity in a relationship.

They choose a group of sincere and dishonest people, take pictures of them and ask another group to point out what is not a sincere object in it.

The people in the group made a completely unknown comment about the people in the picture. As a result, women can guess 62% correctly, while this figure in men is only 23%.

The study also pointed out that the lack of sincerity associated with the temperament of men expressed on their faces and women took this point to make judgments. Specifically, the more a person demonstrates that a man is more likely to be an unfriendly person.

Not only that, women also have a special ability, that is, "sniffing" sexually transmitted diseases (STDs) of men. In this regard, Russian researchers conducted the experiment as follows.

They took a sweat sample under the arm of a group of men over 30 years old. Some of them have gonorrhea, some do not, others have had it but have been cured.

After that, they asked healthy women to smell the sweat patterns and rate them on a 10-point scale, with descriptions like 'very foul' or 'pleasant'. The results showed that the sweat pattern of men who had gonorrhea was much more uncomfortable for women than healthy men.

4. Feeling we can feel very small things

A new study has shown, our emotions are extremely sublime. That sensory organ also helps us to sense things that are tiny, even just the size of a bacterium.

To verify, researchers at the Royal Institute of Technology (Sweden) conducted an experiment that required participants to blindfold and touch 16 different plastic surfaces, from very smooth to slightly grainy. However, these rough places are extremely small, can only be measured in nanometers (one-billionth of a meter) and microns (one millionth of a meter).

As a result, participants can distinguish a surface with a roughness of only 13 nanometers with a perfectly smooth surface. If you still wonder, 13 nanometers is even smaller than the size of a regular flu virus.

This means that if your fingers are as big as the Earth, you can completely feel and feel the existence of cars and houses on the ground.
