Human Body : No Limits!!

Hey Guys!!
It has been a long time since my earlier post. The whole month I was busy with my exams but now I am free and here is what I was wondering.
I was watching this show on the Discovery Channel named "I Shouldn't be Alive" and suddenly a thought took over my mind about The Human Body. Let's dive in.


Do you know that the adrenaline in our body can help us to lift around 3,500 pounds of weight? Can't Believe it. Here's an incident to justify this fact.

In 2006 in Tucson, Arizona, Tim Boyle watched as a car hit 18-year-old Kyle Holtrust.
The car pinned Holtrust, still alive, underneath. Boyle ran to the scene of the accident and lifted the Camaro off the teenager while the driver of the car pulled him to safety. What accounts for feats of superhuman strength such as this one? Are they glimpses into the lives of superheroes' alter egos? Or are all of us imbued with amazing strength?

Although well-documented when they do occur, feats of hysterical strength -- unnatural and amazing strength tapped during high-stress situations -- are not recognized by medical science. This is largely due to the problem of gathering evidence: Instances like these come about without warning, and to reproduce these situations in a clinical setting would be unethical and dangerous.


Not only with strength but our Human Body is equipped with a lot more than this. Our eyes are the most important and delicate sense organ. Any machine or a robotic eye can never compete with our natural ones. They enable us to see the beautiful world around us and also perform wonderful miracles.
A firefighter uses his well trained vision center to find his way through dense smoke to suppress fires and rescue victims. This would not have been possible without the power of the human eye. Our eye has many parts, each of which is designed for a special purpose which it performs brilliantly.



Now moving on from our eyes to our nervous system. Our nervous system comprises up of our Brain, Spinal-cord, and the nerves (neurons). The nervous system monitors and controls almost every organ system through a series of positive and negative feedback loops. This helps us to interact with our physical world. The responses travel at an incredible rate in our neurons. It takes only about 2 ms (0.002 seconds) for a sensation to travel from our sense organs to our brains. This high speed neural network enable a person to fly a helicopter or an airplane which requires high precision and accuracy.


One might say that our bodies perform its best only when we are subjected to the 'extreme' conditions. But, this is not completely true. When we stand, our entire weight is focused on our knees and our ankle. Not only this we also have inbuilt shock-absorbers in our knees and ankle. When we walk or jump a large amount of force is exerted on our legs. But, they perform these tasks quite easily. The largest bone in our body, the Femur (thigh-bone) can withstand a weight of around 1000 kg before breaking. Our body is just amazing. We all are a superhuman from inside.

Well, these are the known capabilities of a human body. But, we can never put a limit to this because we don't know when these limits will be broken. And yes, it does. The Human Body  always pushes its limits. 
                                    
                        I would say that "The Human Body has no limits".
