CAN SCIENCE EXPLAIN EVERYTHING?– I DOUBT…

 

There are some mysteries of human body that science fails to explain. Everyone keeps pondering upon questions like why do we sleep? Or why do we dream? Why do we yawn?..And the list keep going. Well these questions are awaiting to be unravelled. Till then enjoy this post which only tells about the mysteries of human body that science couldn’t explain because we humans are the biggest mysteries to have walked the Earth.

Vestigial Organs and Certain Body Parts:

The appendix is a vestigial organ whose removal does no harm to the normal functioning of the human body. Neither does it inflict any damage nor disturb our body anatomy. In other words these organs exist in the human body, but serve no apparent purpose.

Though some scientists believe that appendix has a role in strengthening the immune system during foetal development, there is no consensus on this. Likewise, some experts believe the tail-bone or coccyx, and the wisdom teeth are remnants of the over-sized jaw and tail which human beings once exhibited. But now are redundant. In fact, the pain that is inflicted due to these organs, can sometimes be excruciating and unbearable. So, whether these vestigial organs are ancestral, evolutionary or rudimentary is a mystery that continues to puzzle scientists.

Presence of Microbes:

For every cell in your body, there are 10 microbes that reside inside you. Some microbes and bacteria like E. coli, Bacteroides fragilis and Clostridia are present in the nose, mouth, the gastrointestinal tract, and on the skin. They help in the metabolic processes that take place inside the human body. These microbes also protect you against disease-causing pathogens and increase the production of vitamins, thus keeping you fit and healthy.

Thus, we know about the presence of microbes, their types and some role that they play in our body. However, why are they present in such huge numbers and what exact role do they serve is still a mystery waiting to be unravelled.

Yawning:

Though there are a number of reasons behind a yawn, scientists are yet to pin down a definite answer to the cause of yawning. Though it helps increase the intake of oxygen, some scientists think it is a way to prevent the brain from warming up, to make us more alert and active.

Commonly associated with fatigue, boredom, and drowsiness, some researchers think that yawning is inherited from our ancestors who yawned to show off their teeth to scare or restrain others. It may also be a way of communicating with others. There is no definite proof as yet about the validity of these theories but we sure know that it is contagious and can occur anytime (I am sure you have started by now).

Sleep and Dreams:

We know that lack of sleep is bad for our health, but science has not been able to explain why we need to sleep in the first place. A theory suggests sleep is essential for the development of the brain and is a restorative function which gives the body a chance to rest and rebuild for the next day. However, if that is the case, then why are our brains active during sleep. However, while sleeping, the exact opposite happens and the brain is constantly alert and active. It is a mystery as to why this happens.

What deepens the mystery is, why do we dream when we are asleep. There are many theories regarding the occurrence of dreams, some scientists say that dreams are a way of analysing things, they reflect your feelings, fantasies, or desires and may help in forming memories. Whether it is for psychological significance or interpretation of signals, the exact cause still remains unclear.

Memories:

How is it that you remember the taste of the pie your grandma made, and the method/formula to solve an equation in algebra even after so many years? Science does not have an answer to this question as well.

How does your brain recall exactly what you want and when you really need some information? How do you form these memories? Where are these memories stored? These are questions that scientists have no definite answer as of now.

Kissing:

Do you remember your first kiss? Of course, you do! It is a memory etched in your mind forever. But why do we kiss, and what is the purpose behind this act, is still a mystery.

Some scientists say it is a form of social bonding and to express your love. Some think that the act unleashes hormones to initiate mating and create intimacy. Whether it is for pleasure, attachment or a combination of psychological and biological factors, we don't know, however a lip-lock feels good and makes you blush.

Blushing :

That brings me to the mystery of blushing. When faced with a difficult situation, why do you get butterflies in your stomach, or turn red and feel the heat rise in your cheeks when someone compliments or praises you?

These are the questions that are yet to be answered by scientists. Do remember that it is an involuntary action, and try as you might, you have no control over.

Adolescence:

Adolescence is the onset of puberty that brings about physical, biological and psychological changes in the body. Experts believe that this prepares the brain for the responsibilities that await you.

But scientists and medical experts are not able to explain why we humans take so long to mature physically and get ready to face the challenges and obstacles in life? I am sure a lot of you experiencing this phase must be equally eager to know the answer as well.

Intuition:

What tells you whether you should accept the tempting job offer or not? What gives you a feeling that something is amiss or is not right? Some call it the gut feeling and some, the sixth sense and some feel it's merely coincidence. You may call it by any name, however we all experience intuition at one point or another.

There are many psychological theories that describe intuition as a sense of the unconscious, perception or contemplation. This does not hold true for all the beliefs and does not justify each and every case that we come across. Hence, intuition falls under the study of psychology as well as occult interests.

The Brain:

The function and working of the brain and the nervous system is probably the biggest riddle that scientists are yet to solve. How does the brain work so fast? Does the brain work alone, or rely on other organs for its smooth-functioning? What happens in various neurological disorders or injury? These questions have puzzled scientists for a long time and are still unanswered.

With the help of brain imaging we know some functions of the brain, however, the things we know are just the tip of the iceberg and the pursuit to understand our brain and its functions seems a long endeavour.

These processes and occurrences were, are, and will always remain an inevitable part of life. They are essential for our survival. We just hope that some day science will provide us with the answers and keys to unravel these mysteries of the human body that has puzzled not only scientists but every individual since time immemorial.
