Amazing Facts About The Human Being

A well-known proverb says, “He who conquers others is strong, but he who conquers himself is mighty.” And, it is only when one embarks on this greatest adventure, of looking within and conquering oneself, that an amazing fact comes forth: that the technologically superior 21st century human being can far easily communicate from Japan to Canada rather than from the head to the toes. Man realises that he is yet, unknown. Today, the average person knows more about computer software than that of his or her inner body, mind and spirit.In order to bridge this lacunae in our knowledge and wonder, I have compiled some amazing facts on what makes us tick. In this process of introspection, you will discover some mind-boggling facts that will make you wonder once again at the depth and precision of the inner self. And at the same time, thank god for giving us the gift of yoga.When the world is busy bringing technology to 21st century standards, yoga endeavours to bring the human being into the 21st century, not with expensive instruments but simply with what one was born.

# The average brain contains about 10,000 million neurons – microscopic nerve cells. Each neuron is also linked to neighbouring neurons by up to 50,000 connections known as dendrites.

# The thumb is so important to human dexterity that a larger proportion of the brain is devoted to controlling it than to controlling the whole of the chest and abdomen.

# Electrical activity in the brain is great enough to power a 10-watt lightbulb.

# The body of the average adult contains 45 litres of water - about 65 percent of the total body weight.

# Besides water, the body contains an assortment of other substances. On average, it has enough lime to whitewash a small shed, the equivalent in carbon of a 12.7 kg bag of coke, enough phosphorus to make 2,200 match heads, about a spoonful of sulphur, enough iron to make a 25mm (one inch) nail – and about 30 gms of other metals.

# 300 million cells die in the body every minute, but the number of cells remains fairly constant throughout our life. Dead cells are replaced immediately.

# Bone is six times stronger than a steel bar of the same weight.

# The stomach’s digestive acids are strong enough to dissolve zinc. But the cells in the stomach lining are renewed so quickly – 500,000 cells are replaced every minute and the entire lining every three days – that the acids do not have time to dissolve the lining.

# Although the kidneys are quite small – about four inches long and two and a half inches wide – the compressed tubes inside them would stretch for 50 miles if extended.

# The intestines, when opened out, would occupy an area the size of a football field.

# The capillaries in the lungs would extend 1,600 kms when placed end to end.

# The air sacs in our lungs, when opened out, would cover an area the size of a tennis court.

# Human beings die more quickly from lack of sleep than lack of food.

# As you read this, you are making two million billion haemoglobin molecules.

# The weight of gold in the average person is 7 mg., and the weight of uranium is only 0.07 mg., although turned into pure energy, this could drive your car for five kilometres.

# The total weight of the bacteria living in the human body is two kgs.

# The ear has two basic functions: to help maintain balance and to react to sound. The organs in the inner ear help maintain equilibrium by sending the brain information about the motion and position of the head. Astronauts experience space sickness at first, but gradually the brain begins to adapt to signals from the inner ear.

# One square inch of skin may hold 650 sweat glands, 20 blood vessels and more than a thousand nerve endings.

# So many red cells crowd the blood stream of a single human that stacked, these cells would reach 31,000 miles into the sky.

# It takes about 200 muscles to achieve one walking step. Forty or so lift and move your leg forward, muscles of the back quickly compensate by pulling on your shoulders and chest muscles to keep from losing balance; the abdominal muscles then contract to prevent you from falling backward.

# Modern science recognises that sleep is by no means a passive process. A sleeper’s brain often is as electrically active as that of someone awake and alert.

# Half of a bird’s brain sleeps while the other half remains alert. Possibly the reason why some birds sleep with one eye open.

# An electrical impulse (signal) moves along the axon (nerve fibre) at a rate of 100 metres a second (over 200 miles an hour, faster than Formula One cars). This means an impulse from brain to toe can arrive in less than a tenth of a second.

# Man is the only animal that sleeps on his back.

# The sound heard by a listener when holding a seashell to the ear does NOT come from the shell itself. It is the echo of the blood pulsating in the listener’s own ear.

# According to a medical writer, there are approximately 21,000 drugs and drug combinations produced by the world’s drug firms, yet the World Health Organisation (WHO) claims that only 150 to 200 drugs are needed to take care of almost all ordinary illnesses around the world. Many experienced clinicians believe the same needs can be met with only 25 drugs.

# The average housewife walks 10 miles a day around the house doing chores. In addition, she walks nearly four miles and spends 25 hours a year making beds.

# Every person alive today carries within his/her body approximately 300 chemicals, which did not exist prior to 1945.

# Women have the ability to produce around three hundred eggs in a lifetime, and men to manufacture three hundred million sperm in a week.

# Turtles and whales can stay underwater for several hours while birds such as ducks and penguins can stay submerged for up to 15 minutes. We, humans, cannot hold our breath underwater for more than about two to three minutes.

Iyengar Yoga: An Introduction

What is Yoga?
Generally, yoga is known to be a 5,000-year-old subject, meant for the refinement and emancipation of the human being. Its scope includes the emancipation of the human being at the physical, physiological, mental, intellectual, emotional and spiritual levels. Hence it is an art, science and a philosophy. The word yoga is derived from the sanskrit ‘yuj’ meaning to bind, join, or unite. It is basically the communion of the individual soul with the universal spirit. But that is the end of yoga. Not all humans, however, aspire for such lofty ends; not all go on to complete their PhDs. But all aspire for basic learning and/or health and thus yoga has something to give to everyone irrespective of age, class, creed, religion, gender and nationality.The subject and practices of yoga are said to have passed down from generations until sage Patanjali, said to have lived in the 5th century BC and known as the codifier of yoga, codified its subject-matter in his classic text, Yoga S…

Light on Iyengar Yoga

One person has given to yoga what yoga itself gave him years ago: a new life. Today, if people speak of ‘Iyengar’ and ‘Yoga’ in the same breath, it is to acknowledge the inspiring life journey of Bellur Krishnamachar Sundararaja Iyengar, better known as B.K.S. Iyengar or, reverentially, Guruji.

Yogacharya B.K.S. Iyengar’s life story, in a way, is interconnected with the rise and spread of the ethos of Yoga across the world. If many countries now celebrate an International Yoga Day, it is mainly because of the seed of the idea planted by Guruji in a talk he once gave. To him goes the credit of making yoga respected as an art and a science, located within a rich philosophical framework.
In the beginning
But the wide recognition of Iyengar yoga as the global gold standard was preceded by a long and difficult journey for Guruji. When Sundararaja, then 16, started on the path of yoga, the odds were against him. He was a frail child during early years – over time, he had tuberculosis, bronchi…

The True Meaning Of A Yoga Day

The best time to plant a tree was 20 years ago; the second best time is now. –Old Chinese Proverb
This practice of yoga is to remove the weeds from the body and mind so that the garden can grow. – B K S Iyengar
My Guruji Yogacharya B.K.S. Iyengar, who was conferred India’s first Padma (Vibhushan) award for contributions made in the field of Yoga, passed away on August 20, 2014, but he is surely here in spirit to see the world embrace this ancient art, science, culture and philosophy.
But what should be the true celebration of a Yoga Day? To understand that we must know that word comes from the Sanskrit root yuj meaning to unite or bind or join. Thus, Yoga aims to conjoin the individual (self) with the universal (force). It is an instrument to sensitise us,and extend our capabilities. In Yoga, what is the instrument? Only what we were born with – the body, mind and breath. Through the different asana and pranayama techniques, we touch these three dimensions within us to enhance our potenti…
