Top 8 Explanations Behind Weird Physical Quirks | mole

We all have silly physical quirks like wiggling our thumbs or wiggling our ears, but there are people who are born with truly unique differences. Sometimes nothing changes in your daily life and it’s just intriguing, but there are also rare medical cases that can really ruin your life.

1. People who don’t have a little voice in their head

Hearing a narrator’s voice in your head when you read is called subvocalization ; most people learn it unconsciously when they begin to know how to “read minds”. Even more invasive, many people hear a inner monologue voice, the “little voice in the head”. A large-scale survey would be needed to determine the number of people involved, but it can be estimated thatbetween 10 and 20% of the population do not have an inner voice and we really don’t know why.

On the other hand, there is a hypothesis to explain the existence of the voice in the head: this phenomenon could be related to the download corollary. In short, we never hear our own voice when we speak, but rather a copy of this sound created by the brain. According to Canadian researcher Mark Scott, it would work the same for the inner voice except that the brain is capable of producing an internal message without making a sound.

2. Absence of wisdom teeth

Today, wisdom teeth are completely useless. They were used, before humans changed their diet, for chewing when molars were too damaged. Most often, wisdom teeth are removed because they no longer have room to grow properly in the jawbone, but they can be preserved if they don’t interfere with other teeth.

We can see that the human species is evolving because some people, just under 20% of the population, do not have wisdom tooth roots. It is in any case the only explanation we have today to explain this absence of null teeth.

3. People who don’t get goosebumps

There are very few people who have never had goosebumps and, like missing wisdom teeth, it’s probably a evolution of the species. When you are cold, hundreds of thousands of thermoreceptors distributed throughout the skin send a message to the hypothalamus. It transmits the message to the sympathetic nervous system that activates horrible muscles (hair straighteners) in an attempt to warm up the body. The hairs then stand up against the skin to create a thin layer of insulating air; Goosebumps therefore serve to combat heat loss to protect against cold.

With the evolution of the species, the human body has much less hair than before and therefore this technique is less effective; therefore, we can think that people who never get goosebumps just don’t have these horrible muscles, real human 2.0.

4. The different forms of fingerprints.

There are three different fingerprint shapes: swirl, loop-start, or wave. The thing is that only 5% of people have wave-shaped fingerprints. A new Chinese study revealed in early 2022 that the shape of fingerprints is influenced by the EVI1 gene, which plays a role in embryonic limb development. The patterns of your fingerprints are actually related to the length of your fingers.

5. People who never have a rumbling stomach

Belly gurgles, called rumbleThey are perfectly natural. It is a manifestation of the stomach preparing for digestion and is even stronger when the stomach is empty because it resonates. If your stomach doesn’t growl, it may be because you never eat at the same time: you feel hunger differently and your stomach doesn’t automatically prepare for digestion.

6. Hair of different colors

There is a physical anomaly calledhyperchromia or skin hyperpigmentation; It is characterized by hair with two very different colors. This disorder is due to an excessive accumulation of hair pigments or a disordered distribution of pigments during melanogenesis. It is quite rare but nothing serious.

7. People who cannot recognize faces

people with prosopagnosia they have great difficulty recognizing faces, even those of loved ones or people they see on a daily basis. Some people are even unable to recognize their own in a group photo.

According to some studies, this could be explained by a difficulty in integrating local components into a whole: facial features are perceived independently and not as a whole. Therefore, affected subjects are required to retain the precise features of a face in order to recognize someone.

“We already met in fact” Okay, I don’t remember you. Have you ever thought about being more memorable and less insignificant? »

8. Alien hand syndrome

Alien hand syndrome is a very rare neurological disorder (and definitely more serious than the previous points). As in a bad horror movie, people with this syndrome lose control of one of their hands, which seems to be acting under the will of another person. She can become dangerous and chase after her owner, which is super creepy.

This disorder can appear after an operation that aims to separate the two cerebral hemispheres to relieve epileptic seizures. It can also occur due to a brain tumor, stroke, or other neurological disorders.
