Blind Sight is enough to pick emotions

What if someone says that you don’t need to consciously look at faces (of other persons) to pick emotions on them? Is it really possible for us and if yes then exactly how? Do only faces can express and convey emotions? Does the sixth sense really exists? Is mind reading just by looking at bodies possible?
These are the few basic questions Prof. Dr. Beatrice D. Gelder (a renowned Cognitive Neuroscientist and Neurophysiologist) and her team has conducted an elaborate experiment at Tilburg University to find answers for. What they call this amazing (or “supernatural”) ability to pick emotions without clear visual clues is as ‘blind sight’. It's really interesting!
Faces with emotional expressions
She conducted an elaborate scientific experiment in a lab with a numerous individuals (or subjects) having or suffering from blind sight or blind vision which is a phenomenon in which visual cortex in one hemisphere of brain gets damaged due to stroke which ultimately leads to the deficiency of conscious visual perception or clue collection.
(Affective) Blind Sight or Blind Vision is the residual visual ability in the patients who has suffered damage to their primary visual cortex (V1, striate cortex). They react reliably to the emotional degree of stimuli presented to their blind visual fields but they cannot consciously report presence and properties of the stimuli.
Bodies expressing different emotions
The team found that the patients responded unconsciously by moving or twitching muscles of their own faces to mimic the same emotions when different emotionally charged faces were shown to the eye of patients suffering from the blind sight or blind vision phenomenon. Movements and twitches of their facial muscles were recorded with sensors.
This is a revolutionary discovery about our brain's ability to pick emotions in others. Her work was published by Scientific American journal. Also, a short clip on the entirely experiment was broadcasted in the episode “Is there a Sixth Sense?” of the famous scientist documentary series called as “Through the wormhole”.
Please kindly view below clip (link: thoroughly to understand what she and her team tried to reveal or unearth circuits or parts inside our brain that help us to decode emotional clues on faces and bodies of others without conscious visual perception of them.

Turtle Effect: Body response under threat

We all remember our good old childhood days and especially cheerful play time with our family and friends. Out of many amusing and thrilling activates that each of us might have had, tossing in air and catching back in repetition done by elders was mixed with excitement and fear. Even though the vertical distance a child is tossed at isn’t unsafe but definitely frightening for it.

Almost every child on this planet might have experienced the mixed feelings deep inside even though it couldn’t explain it into words. Still, that very mixed feeling thrills and amuses or most of us in our routine life.

We like to get scared but obviously in a controlled situation and we’re ready to pay for same too. In fact, whole multimillionaire amusement industry has spread its roots over the planet by scaring and thrilling us only. Now, this same industry is looking forward to scare and amuse us above surface of earth.

I’m talking about space tourism or zero-gravity experience that a person other than astronauts could enjoy. I really don’t know the exact date I could (afford) fly in an outer space but I always wanted to take similar kind of experience on ground.

Recently, I got an opportunity to visit Adlabs Imagica - an amusement park which is located near Khopoli (Mumbai, Maharashtra, India) and close to Yashwantrao Chavan Expressway. Coincidentally, my wife was with me to experience an enormous thrill of different rides and simulations.

By taking three different roller coaster rides, I could test my courage and also feel the thrill deep inside my gut. Almost everybody was screaming and shouting till each ride coming to an end. Even after trying harder, we couldn’t stop ourselves by doing so because body was in total control of an unconscious mind.

While coming down from height quickly, moving faster on banked turns and getting rolled   in 360 degrees on steel rail; our bodies were getting hurled or tossed and pushed abruptly in almost every direction. Many of us must have felt mild, moderate or strong tingling sensation inside stomach especially while looking down at steep slope from very highest points but suddenly realizing that we cannot escape from moving seat going down on same path.

Body’s quickest (within milliseconds) and natural response in this kind of situation is to protect itself from potential harm that might cause by falling down from above. Watch this video clip and experience what a rider might be feeling.

Even if we consciously know that we won’t fall off (of course, until protecting arrangement malfunctions) the seat, we tightly grip the straps, bars and railings to avoid falling. While going down deep from above or taking a dive, we unconsciously push our bodies towards the back of seat to minimize gravitational drag and retain center of gravity at its place as much as possible.

Most astounding thing we can easily observe or realize is that most riders on roller coaster or inside any threatening simulators pull all movable parts of body inside and towards torso (an upper body).

This phenomenon is called as ‘Turtle Effect’ because a turtle does same in face of danger. It pulls all movable body parts (legs, tail and neck) inside its shell to avoid potentials injuries to them and thus increase chances of survival. We clearly know that we don’t carry any natural or artificial shell or armor like a turtle all the time and also we walk on two feet only.

Still, we protect our neck by raising both shoulder high as if they are about to touch ears. We clench our feasts and tug or keep our forearms close to our neck. We clasp our legs together, pull them towards abdomen, lock them at ankles and grip them tightly sometimes.

How this response might have evolved in us in the first place? It has evolved in us the same way we’ve evolved into humans from creatures. Our remotest ancestors didn’t roam on two feet (limbs) but four. In fact, they used to roam and forage inside oceans only with help of fins before evolving into land roaming quadrupedal (four limbed/legged) amphibians.

Let me make it clear here that our remotest ancestors weren’t fishes but they were having overall philological features almost similar to a fish - except the ability to breathe by nose.

Retreated Turtle
Vertebral and quadrupedal body structure i. e. ability to adapt different postures with the help of spine or backbone (vertebras connected in an elongated shape) and roam on limbs, ultimately led to development of rib-cage - an astounding structure made up of bones to cover and protect different life supporting organs.'

Still, stomach remained unprotected because of its functions like storing food, digesting it and exerting wastage. Since stomach needs to expand and contract in cycles, any solid structure or protection can hinder its normal functions.

In face of any physical risk or an advance of a predator, only thing any vertebral and tetra-pedal creatures can do is to pull all moving body parts inside to provide protection to them and also to cover exposed stomach. Thus two great goals are met while defending most of the body and multiplying the chances of survival.

This strategy was further inherited by all descending species that evolved to roam on land and fly in the sky and climb on trees. As we evolved from the greater apes, we still adapt same defense tactics that was evolved before millions of years ago.

If you get an opportunity to ride a roller coaster or seat inside a scary and body shaking simulator, try to keep all your movable body parts in perfectly normal position. You may not because of unconscious suggestions you might get from deep inside.

Since we are not designed to fly and dive from tens and hundreds of feet like bird, our body tries to protect itself from falling on ground and getting hurt by either moving hands rapidly like a birds or getting itself pulled inside like a turtle.

Couple in trouble?

When a man and a woman fall in love with each other, it speaks loudly through their body language. Love doesn't remain hidden or suppressed for a long time and shows up in one or other form. People start talking about them and different stories are shared or gossiped.
Eventually, we come to know that the couple has decided to live with each other together. Knot is tied between both of them and they are officially declared as a married couple publicly by performing some rituals and by giving a feast to the attendees.

Some couples may choose to stay in a short-term, a live-in relationship or an uncommitted 'venture' but still they have to make some adjustments. Relationship between a man and woman is natural and wonderful but it is also filled with many challenges, unforeseen incidents and uncertainties.

every romantic relation has a glorious and rosy beginning, not all stories progress ahead very pleasantly. Every couple experiences rough days, monotonousness or stagnation in their relationship but their mindset determines future of their relationship.
Those who give enough time to develop healthy and positive outlook towards each other, survive through rough patches and keep flourishing in unimagined ways. Developing a strong, healthy and respectful bond between two individuals takes a a lot of time..

However, not every person is the same when it comes to have patience, manage negative impulses and guide oneself into a right direction. When many things go beyond peaceful compromise, a couple starts moving into a disappointing stage - separation.
"What exactly went wrong?"
In daily routine, both men and women often get busy with their tasks at hands in such a way that they could hardly pay attention at each other. Traditionally, it’s the woman who starts filling unsafe when enough attention is not paid at her and some fruitful conversation doesn’t take place between a husband and wife. Sometimes, one partner starts drifting away and taking less interest into an existing relationship.

Many people, mostly men, get into a shock after coming to know that their partner is no longer enthusiastic in the relationship they both had set out for. Unlike flashy and telling courtship signs, a man and woman drift away from each other silently. Aren't there any expression, signs or clues, prior to separation?

Expression of Contempt
According to Prof. Dr. John Gottman (a psychologist well known for his work on marital stability and divorce prediction), a telling sign for a couple on verge of separation is not anger and sadness but contempt and disgust.
Unlike pair bonding facial expressions, gestures and maneuvers; contempt and disgust convey unconscious disrespect and disliking towards each other. Both emotional expressions silent convey the wish to stay away from each other. Both are distancing emotional expressions.

One partner may not realize that the other is expressing contempt and/or disgust during regular interaction but identifying these alarming emotions on face (and body) can help in saving a troubled relationship. Moreover, contempt and/or disgust are expressed not only by couples in rocking relationship but also by any two persons irrespective of their genders.
Expression of Disgust

Contempt can be a result of suppressed anger and/or heightened social status and desirability level of one or both partners. It can be readily observed in today’s liberal environment that allows both partners to climb professional, social, economical and materialistic heights with many potential partners in sight and in presence at their respective workplaces.

On the other hand, disgust simply means - “I don’t want to or can't stay by your smell”. It’s a state of utter dislike but not disagreement with the other person. Disgust is also related with the signature smell (pheromones) that body of one person produces and the another inhales it unconsciously. Pheromones play a greater role to play in romantic lives.

More often these two expressions are given away by one or both partners during every single face to face interaction and also while discussing about partner with some other person; more there are chances of their separation in (near) future.

Out of these two alarming expressions, women are more likely to express disgust and men are more likely to express contempt on their faces unconsciously. Women too can show contempt like men do.

Body Language of Narcissist

Can you spot a narcissist i. e. a grandiose, self-submerged, entitlement seeking and exploiting individual, just by observing its behavior? Both self-confessed and unidentified narcissists are all around us and we’re likely to face them at almost every location and in different situations in our entire life.

Like every other individual living with and around us in our society, a narcissist individual too makes for living and struggles for survival like all of us. Then what’s so wrong with that kind of individual after all?
"I, Me and Myself!"

Everybody needs to sustain itself through adversities, challenges and dangers which is the fundamental necessity of every living and flourishing creature and not just human beings. One needs to harbor self-love, self-respect and self-worth for same. It gives us confidence, strength and social value.

Only thing is that few of us are extremely self-loving individuals and this turns them into narcissist manipulators. Principally what every highly narcissist individual does most of time is attracting attention of others towards oneself and at some extent - exploit and manipulate others for the same.

They have a definite plan, strategy or mission to get identified in the crowd. They may look very charming, intelligent and tidy by their appearance. At some extent, narcissist men or women standout in being a magnet for members of an apposite gender and especially those with genuine low self-esteem.
"WHO else is there, other than ME?"
Unlike open-ended and “away from once body” gestures, they gesticulate in such way that their palms face their own bodies most of time. They try to accentuate their presence and make maneuvers that saliently convey to others, “Hey, I’m here! Aren’t you looking at me?”. They would invade your space suddenly and remind that you didn’t greet them as per their own expectations.

They would raise their voice to make their presence felt without any hesitation about their contribution to noise pollution. They would put on glossy or gleaming cloths and carry costly accessories so that people should praise them. They are prince or princess in their very own eyes, regardless of how others see them.

Some of behavioral characteristics of a highly narcissist men or women, like trying to attract attention of others in crowd or raising oneself above others, can be observed in an individual who is courting or wooing partners.
Only difference is that the courting or flirting  individuals pays equal attention at potential partner, remains submissive yet appealing, tries to coordinate with movements and expressions of deserving partner (i. e. “mirroring”) and appears to inviting or accepting.

On the contrary, a highly narcissist individual tries to overrate oneself and creates a scene of having a great level of self-esteem which the individual completely lacks in the first place. If they're dating or courting somebody then they would try to manipulate them to spill out the words of appreciation and praise about themselves.

Another remarkable characteristic of a highly narcissist individual is that he/she tries to take credit of what has been achieved by others. They would come forth to shake their hands with you and say, “It was only me to encourage you from the beginning.” or “It has happened because of my company.” or “It happened because I greeted you in the beginning”.
They wouldn't be able to show facial expressions that match with their words and actions while appreciating, admiring and praising others. Also, they wouldn’t make statements like “Didn’t I tell you that you could make it?” or “You had all necessary qualities and the potential!”. They would keep reminding you about what ‘favors’ they had done(?).

Following are the other behavioral characteristics and patterns of an extremely narcissist individual:

1) The individual has an extravagant sense of self-importance. The individual tries to exaggerate himself/herself, qualities, skills and talents with expectations of being recognized as superior.

The individual is preoccupied with fantasies and dreams of unlimited success, power, brilliance, beauty or ideal love and always tries to pursue them.

The individual believes that he or she is “special” and unique and can only be understood by or should associate with other special people or institutions.

The individual requires excessive and continuous admiration and appreciation. In fact, he/she seeks every opportunity of getting admired and appreciated.

The individual has a very strong sense of entitlement i. e. unreasonable expectations of special treatment and/or compliance with his or her expectations.

The individual exploits others to achieve or fulfill his own goals and purposes. Such individual often roams only with those appreciate him or her and follow instructions.

The individual lacks empathy and appears unwilling to recognize feelings and needs of others. Such individual creates a group of underachievers and stands in its center.

The individual is often jealous of others but believes that others are jealous of him/her on contrary. They wouldn't control their impulse and let it harm others.

The individual regularly shows arrogant, haughty behaviors or attitudes. He denies or ignores existence of those individuals who reminds him/her about shortcomings.

The individual looks very charming and witty but always tries to make fun of others. Such individuals greets others in a way that he or she’s doing favor on them.
11) The individual is addicted and involved in substance abuse. They may not be able to stay in a one (committed) relationship for a long amount of time.
12) The individual's friendship with other person last as long as it serves the individual and fulfills its empty ego. The individual doesn't bother to disrespect others.

There are number of reasons that turn a tender, loving and easy going child turns into an extremely narcissist or noxic individual in the future who gives importance to itself and doesn't really care about others and their feeling and/or emotions. In fact, narcissist is empty from inside that's why it creates a lot of noise outside.
Narcissist individuals aren’t like psychopaths who have cruel intentions in their minds but actually they are victims of biological, genetic, psychological and parenting factors that shape their personalities in an egocentric manner - exactly like the prince (or princess) who falls in love with his (or her) own reflection in water.

Could you believe that everybody, including you and me, possess certain level of narcissism or excessive self-love? Actually, most of us are narcissists but some are beyond the normal or acceptable level of narcissism. Extremely narcissists are self-destructing individuals.

When put on a scale of narcissism or conducted psychological assessment, every  individual would find itself at different level of narcissism. If you really want to know then you can undergo a test by following this link and giving honest answers only.
Actually, a narcissist individual isn’t a subject to run away from or hate but actually the individual needs great amount of help, care and sympathy from other people to overcome narcissism.

Self-communication by gesturing

Let it be nonverbal, spoken or written, communication is vastest domain of our life. Many of us think that any exchange with only others is communication but this is not true at all. We communicate with ourselves too and on both cognitive (related to perception, learning and reasoning) and emotive (related with emotions) terms.

We communicate with ourselves too but as per situational demand only. We communicate with ourselves in different situations the same way we emphasize, reiterate, remind and draw focus of others at something or somebody by using hand gestures and through touching ourselves or others.

Have you ever noticed yourself stroking or rubbing you chin when you're thinking deeply and trying to understand something complex? Have you ever tried to locate or find something without making any pointing or allocating gestures by your hands?

If you try to refrain yourself from not making any hand gestures to remind, allocate, symbolize or illustrate something; you would experience that you're not able to perform many tasks more efficiently or quickly. So the question is - Why shouldn't we be able to emphasize, reiterate, remind and draw focus at without making hand gestures?

Development of cognitive abilities and intelligence (problem solving) is strongly related with pattern recognition, spatial allocation and establishing co-relation among different entities that we come across throughout our life time. We get inputs through different senses but vision has greatest share - almost 90% in a visually fit person.

Everything we capture through eyes is stored inside our brain (visual cortex) in form of blueprints, maps or something alike. Representation of complex ideas or illustrations is entirely based upon our visual memory. It means that we can explain something based upon what we've saw or observed till date.

So what could be the purpose of hand gestures, touching or even some facial emblems during conversation? Pointing at something, mimicking to position or hold something in front of ourselves (by hand) and representing different things through hand gestures helps us to recall and also strengthen graphical memories related with entities.

It's a kind of close loop communication we do with ourselves. Also, others can easily understand graphical representation over words so we share our memories with them.
Spatial Gesturing: Sensing space around yourself.

Should leaders show emotions?

Modern world and especially workplace has remained not so formal as compared to former generations. We’re witnessing, adapting and adjusting ourselves with new ‘styles’ of leadership. We observe political, corporate and social leaders involving with sub-ordinates more and more than only discussing about serious stuff with others or their superiors.

However, core requisites for being a good, result oriented and accepted (being accepted by followers is very crucial) leader haven’t changed much since hundreds, thousands and perhaps millions of years.
A good leader should be master of its own emotional expressions.
First of all, any leader shouldn’t assume himself/herself as superhuman entity or alien being altogether. Like any other human being, a leader has emotions and ways to express them. Showing and expressing emotions verbally, nonverbally and para linguistically should be used mostly to make followers and sub-ordinates aware of true potentials they have and different areas they could improve.

Throwing speech in an upbeat and firm tone of voice is what good leader can do to motivate its followers and sub-ordinates. We see this in movies - a knight provoking its soldiers to fight with enemy when their morale is down.
Each emotion has a purpose.
Every emotion serves a unique survival and socialization purpose. Throughout million years of our evolutionary history, we've learned and got in heredity the ability and skill to express, read emotions and also control their expressions on purpose i.e. voluntarily manipulation of emotional expressions. A good leader has to have all these skills.

Although most part of emotional expression is entirely unconscious, degree and validity of every expression is entirely contextual - kind of situation, cultural & gender norms, people involved into it, necessity of own (of a leader) involvement and severity & scale of potential outcome of any emotional expression. Context has greater importance when we try to necessitate and also validate an expression of any emotion.

A leader should be motivator.
A leader should be more skilled and also quick (as compared to its followers, sub-ordinates or team members) in picking emotional clues and react to them appropriately - more specifically in constructive manner. If a leader wants to express emotions then he/she should be well aware of contextual factors (as mentioned above) before expressing any emotion.

Sometimes, not expressing emotion at the moment it induces in subconscious mind and conveying a message to sub-ordinates or team members at any other time through a different channel (verbal or nonverbal) could be wise decision. A leader has to gain the mastery in reacting appropriately and reasonably to something in the first place.

If a leader wants to restrain from expressing emotions on face, it can act upon them constructively. Facial emblems, vocal tones, postures, body positions, body movements and hand gestures can be used more effectively to convey emotional message to people.

A leader should express its emotions but should keep their expressions in check as much as possible so that they don’t create mess. Yelling, shouting, grunting and taking out frustration is not expected at workplaces or in public. Negative emotions shouldn't be expressed openly.

Good posture is Healthy

You can conduct seemingly easy experiment on your own after reading this article. Fill a glass with water (on any other liquid) and hold it in one of your hands. You can choose any other (light or moderate weighted) object too for this experiment.
You might be thinking that what this fellow is asking me to do is what you do routinely - holding a glass, cup, mug or bottle in hand to drink water, tea, coffee or other beverages.

You might be holding or handling these kinds of containers for less than 2 or 3 minutes on average at a single instance. What’s so different with this so-called experiment then? Specifications of this seemingly ordinary experiment are not over yet. Please stay with me.

I’m asking you to hold any object by stretching you hand straight and keeping it away from your body. You have to keep your hand steady and not let it bend at elbow. Obviously, you shouldn’t take support of anything and also take breaks
at all. To arrive at a conclusion of the experiment, you should hold the object until you start feeling trembling, pains and tingling sensation in muscles of your hand.

Why supposedly strong muscles, which have been sophisticatedly designed to lift heavy load than that of one you’ve hold in your hand, started to ache after few minutes only? Answer to this question, which you would know after going through rest of this article, is definitely eye-opening.

Ancestors used to walk on four feet (limbs).
Before evolving into tree dwelling apes, our remote ancestors used to roam on four limbs. As we can easily observe, vertebral column i.e. backbone or spine of all four legged animals remains horizontal. Standing and walking on four legs (i. e. quadrupedal anatomy) offers them more flexibility, good balancing ability and capacity to attain more speed while running.

That’s the very reason why the fastest animal on earth is cheetah and not us. Also, almost all quadrupedal (four-legged) creatures can achieve balance and walk on their feet within just few minutes or hours after taking birth.

"Human body is more vulnerable due to its bipedal anatomy. We can easily adapt a defensive posture in danger."

On the other hand, we have a unique ability to stand and walk on two hind limbs or legs (i. e. bipedal anatomy) that we feel very proud about. Moreover, it's only the bipedal anatomy which developed broader shoulders in men and wider hips in women.
This kind of anatomy allowed us to lift different things by forelimbs or hands, carry them, climb flexibly, observe much clearly over a large distance with wider visual angle and move from one location to other by spending less amount of energy.
Probably you might knew that our spine is made of interconnected bony segments which are stacked upon each other and called as vertebrae. Also, our spine has four different sections and curves which are Cervical, Thoracic, Lumbar and Sacral.

While standing, taking rest, walking or running on four legs; quadrupedal creatures hardly have to pay conscious attention at their body posture and natural curves of their spines. Watch carefully at your dog or cat when it seats, stands or runs.

Only in the condition of not having enough energy and essential body parts unfit or in a bad shape (infested, deformed, amputated or wounded), bad body posture could negatively affect speed of roaming, ability to perform different tasks and their natural spinal curves.

We too are not exception to this but I believe that only we humans suffer from spine related pains, deformities and decay by most. Unlike four legged creatures, we need to maintain accurate balance along with keeping upper body erect to carry our different kinds of static and dynamic tasks.

To be able to adjust ourselves with various operational demands, we eventually alter spinal curves, distance between two vertebrae and pressure on the whole vertebral column. We twist, jerk, pull or burden it instantaneously, momentarily or over a considerable amount of time.

"Pat your back on your own frequently because it reduces issue of frozen shoulders. Simple idea but great effect!"

As many anatomists would agree, the lower section of our back is not much perfectly designed (or not ‘evolved’ correctly through millions of years). When it comes to perform activities by adapting an erect posture, this very design defect speaks (and also ‘hurts’) very loudly. Perhaps, only human babies need to learn and also practice to walk on two feet.

Ability to stand and walk with the perfectly erect or upright posture comes only after few years after a baby's birth. We insist on good posture because it’s an inevitable part of influence and impression in society but we hardly relate it with health.

Vertebral column or spine is a bridge of life force that flows between brain and rest of the body. Vertebrae or one of the bony segments of the spinal column that rests on other vertebrae with soft disk or cushion in between, is one of the vulnerable and also complex structures.

Spine connects the whole body with the brain and also provides energy and signals to different body parts through spinal cord. Both stagnant life style and exhaustive workout done by adapting wrong postures accelerate the process of spinal decay and deformation.

Like any other moving body part that is made up of blood veins, nerves, bones, tendons (band of inelastic tissue that connects muscles with bones) and muscles; entire spine or backbone is spring like a long metal spring but a little more complex than it.

One question might be raising in your mind - Why we experience inflammation and pains in back, neck or arms only few minutes after applying pressure or strain? Crucial importance of good posture, workout and physical activities won’t make sense properly until we don’t get answer of this big question.

"Musculoskeletal pains and inflammation, if persisted over a long time, can lead to performance degradation and most importantly - deterioration of self-confidence."

Bone, tendon and muscles: All tied up together
Composed by elastic and fibrous tissues, muscles have their own dynamics and chemical processes. Muscles remain fit and also painless when they are moved in regular intervals because only movements ensure supply of blood and oxygen. Lactic acid gets generated as by-product of exercise but it also needs to get washed out through adequate blood circulation.

Holding any body part in a one position or configuration and putting strain on it in repetition causes contraction of muscles and ultimately disturbance in process of circulation of blood, nutrients and oxygen. You might have heard about an athlete suffering from tennis elbow.
In absence of nutrition and accumulation of lactic acid, muscles start to ache, tingle and inflame. If muscular pain and strain are not relived within proper time then it badly affects not only muscles but also tendons and nerves. Spinal column is also surrounded by muscles, nerves and tissues. Muscles provide support to it.
Which posture you think is correct one?

"Incorrectly lifted load of 5 kilos puts pressure of 80 kilos on lumbar area i.e. 15 times higher than original weight."
While sitting at one place for a long time in any particular posture, we put pressure on our whole spinal structure and thus kicking off the vicious process of musculoskeletal decay. Upper body weight also adds to the pressure on lower body, which is felt in lower back and abdominal region.

If posture isn’t changed or any body movements are not made to re-establish sufficient blood supply then not just spine but all related body parts get exhausted and start to ache and inflame. Over a considerable amount of time (in months or years), person working  stagnantly starts to feel lack of energy, enthusiasm and lightness from inside.

"Nearly more than 80% of today's youngsters in cities suffer from pains in back, neck, shoulders, arms, wrists, palms and feet. Only reason is stagnation and spending a of time with motorbikes, computers, cell phones and television."

Although we all love luxury and relaxation, it's crucial that our body is moved and not  kept stagnant for a long time. In fact, stagnation deteriorates it much faster as compared to a lifestyle filled with movements and actions. While sitting, walking or doing different tasks; only good body posture ensures spinal health and continuity of liveliness.

Try to remain in a good and upright posture as much as possible because it’s not just healthy but impressive too. Respect your body and pay attention at your posture. Be smart and stay fit, healthy and performing for a long time!
Good and impressive sitting body posture with and without computer
"Stagnant lifestyle coupled with bad static and dynamic postures make situation worse or nightmarish."

Between year 2008 to 2013, I've gone through worst health and performance conditions. Pains, swelling, inflammation of muscles and tendons in back, neck, shoulders and wrists was about to put me out of action permanently. However, my own excruciating conditions and ordeal has taught me a great lesson in life.

I've successfully recovered from severe pain in back and neck only by adapting a proper posture, changing it frequently and doing rigorous exercise on regular basis. Good posture is a health insurance and a very impressive too. It has changed my life and also how people perceive me socially.

Would you still like to conduct or continue the experiment, mentioned in first two paragraphs? Certainly not I guess. If you want to test that how your muscles and tendons respond to long lasting stagnation, go ahead and try it out carefully. It would end in ailing but I'm sure that you would become more conscious about your body and its dynamics.
