 Amazing facts about human body -

Facts 1 The average red blood cell lives for 120 days. 2 There are 2.5 trillion (give or take) of red blood cells in your body at any moment. To maintain this number, about two and a half million new ones need to be produced every second by your bone marrow.That's like a new population of the city of Toronto every second. 3 Considering all the tissues and cells in your body, 25 million new cells are being produced each second. That's a little less than the population of Canada - every second ! 4 A red blood cell can circumnavigate your body in under 20 seconds. 5 Nerve Impulses travel at over 400 km/hr (25 mi/hr). 6 A sneeze generates a wind of 166 km/hr (100 mi/hr), and a cough moves out at 100 km/hr (60 mi/hr). 7 Our heart beats around 100,00 times every day. 8 Our blood is on a 60,000-mile journey. 9 Our eyes can distinguish up to one million colour surfaces and take in more information than the largest telescope known to man. 10 Our lungs inhale over two million litres of air every day, without even thinking. They are large enough to cover a tennis court. 11 We give birth to 100 billion red cells every day. 12 When we touch something, we send a message to our brain at 124 mph 13 We exercise at least 30 muscles when we smile. 14 We are about 70 percent water. 15 We make one litre of saliva a day. 16 Our nose is our personal air-conditioning system: it warms cold air, cools hot air and filters impurities. 17 In one square inch of our hand we have nine feet of blood vessels, 600 pain sensors, 9000 nerve endings, 36 heat sensors and 75 pressure sensors. 18 We have copper, zinc, cobalt, calcium, manganese, phosphates, nickel and silicon in our bodies. 19 It is believed that the main purpose of eyebrows is to keep sweat out of the eyes. 20 A person can expect to breathe in about 40 pounds of dust over his/her lifetime.

21 There are more living organisms on the skin of a single human being than there are human beings on the surface of the earth. 22 From the age of thirty, humans gradually begin to shrink in size. 23 Your body contains enough iron to make a spike strong enough to hold your weight. 24 The surface area of a human lung is equal to that of a tennis court. 25 Most people have lost fifty per cent of their taste buds by the time they reach the age of sixty. 26 The amount of carbon in the human body is enough to fill about 9,000 'lead' pencils. 27 One square inch of human skin contains 625 sweat glands. 28 When you blush, your stomach lining also reddens. 29 The human body has less muscles in it than a caterpillar. 30 If you could save all the times your eyes blink in one life time and use them all at once you would see blackness for 1.2 years! 31 The life span of a taste bud is ten days. 32 It's impossible to sneeze with your eyes open. 33 Give a tennis ball a good, hard squee ze. You're using about the same amount of force your heart uses to pump blood out to the body. 34 The aorta, the largest artery in the body, is almost the diameter of a garden hose. 35 Capillaries, on the other hand, are so small that it takes ten of them to equal the thickness of a human hair. 36 Your body has about 5.6 liters (6 quarts) of blood. This 5.6 liters of blood circulates through the body three times every minute. 37 The heart pumps about 1 million barrels of blood during an average lifetime--that's enough to fill more than 3 super tankers. 38 Babies start dreaming even before they're born. 39 The human body can function without a brain . 40 Humans are the only primates that don't have pigment in the palms of their hands.

S.No Facts 41 10% of human dry weight comes from bacteria. 42 There is more bacteria in your mouth than the human population of the United States and Canada combined . 43 Every square inch of the human body has an average of 32 million bacteria on it. 44 A fetus acquires fingerprints at the age of three months 45 You sit on the biggest muscle in your body, the gluteus maximus a.k.a. the butt. Each of the two cheeky muscles tips the scales at about two pounds (not including the overlying fat layer). 46 The tiniest muscle, the stapedius of the middle ear , is just one-fifth of an inch long. 47 The average human head weighs about 10 pounds. 48 The average human brain weighs three pounds. 49 The DNA helix measures 80 billionths of an inch wide. 50 Your eyeballs are three and a half percent salt. 51 Head lice actually prefer to live on clean heads, not on dirty ones. 52 If Barbie were life-size, her measurements would be 39-23-33. She would stand seven feet, two inches tall and have a neck twice the length of a normal human's neck. 53 It takes about 20 seconds for a red blood cell to circle the whole body. 54 An average human drinks about 16,000 gallons of water in a lifetime. 55 Beards are the fastest growing hairs on the human body. If the average man never trimmed his beard, it would grow to nearly 30 feet long in his lifetime. 56 Humans shed about 600,000 particles of skin every hour - about 1.5 pounds a year. By 70 years of age, an average person will have lost 105 pounds of skin. 57 It only takes 7lbs of pressure to rip your ear off. 58 When you sneeze, all your bodily functions stop - even your heart. 59 Human teeth are almost as hard as rocks. 60 You burn more calories sleeping than you do watching T.V.

Madam Marie Curie honoured

Poland will hold observances next year to mark 100 years since the Polish-born scientist Marie Curie won the Nobel Prize in chemistry for her discovery of radioactive elements polonium and radium.

Poland’s lawmakers adopted a resolution Friday naming 2011 the year of the researcher, who was born Maria Sklodowska in Warsaw in 1867.

The lawmakers said she was one of the “most outstanding scientists of our times.”

In 1891 she left Warsaw which was under Russian rule at the time to study in Paris, where later she and her husband Pierre Curie researched radioactive elements. In 1903 they jointly received a Nobel Prize in physics and in 1911 she won a Nobel in chemistry for her discovery of polonium and radium, work that laid the grounds for X-ray tests.

The "Sandwich Gamble".

The Sandwich takes its name from the notorious British gambler John Montagu, Earl of Sandwich. In 1762, at the Beef Steak Club in Covent Garden, London, Montagu spent twentyfour hours gambling without a break. He asked for meat and slices of bread to be brought to him so that he could eat without interuptting his game. The conveniant result appealed to to Londons fashionable society and teh word Sandwich stuck.

Hiccups.

Hiccups

If you've frequently got a case of the hiccups, try slowing down when you eat and drink, suggests Dr. Plasker. Doing either too quickly causes your stomach to swell; this irritates your diaphragm, which contracts and causes hiccups. You may also get hiccups in emotional situations or if your body experiences a sudden temperature change. In both of these cases, the hiccups are a result of a glitch in your nerve pathways, which is why a sudden scare - which might shake up and reset your nerves - can sometimes end an episode.

Gertrude B. Elion

George H. Hitchings

The Nobel Prize in Physiology or Medicine 1988 was awarded jointly to Sir James W. Black, Gertrude B. Elion and George H. Hitchings "for their discoveries of important principles for drug treatment".

Why do we yawn

If your body is low on oxygen, your mouth opens wide and tries to suck more in. Yawning is a way to regulate the amount of carbon dioxide and oxygen in your blood. Unfortunately, yawns are nearly impossible to stifle.

Fascinating facts

• Rubber bands were fitst made by Perry and Co. of London in 1845.
• Charles Gould invented the stapler in 1868 for use in bookbinding.
• A vaccum flask was demonstrated in 1892 by the Scottish physicist James Dewar. His mother in law remained sceptical of a flask made for his son in 1902 and knitted a wollen cosy for it to make sure that its contrnts remained warm.
• Vaccum flasks were first marketed in1902 by the German Reinhold who held a competition to name the invention. The winning entry was Thermos, the Greek word for'hot'.
• In 1900 the Norwegian Johann Vaaler patented the paperclip.
• The aerosol can was invented by another Norwegian, Eric Rotheim, but the idea was not developed commercially until 1941. when Lyle Goodhue and William Sullivan took a patent in the USA. They saw the spray can as an ideal container for insectisides.

The Story of the Escalator

Jesse Reno, Charles Seeberger
An escalator is a conveyor type transport device that moves people. It is a moving staircase with steps that move up or down using a conveyor belt and tracks keeping each step horizontal for the passenger. However, the escalator began as an amusement and not as a practical transport. The first patent relating to an escalator-like machine was granted in 1859 to a Massachusetts man for a steam driven unit. On March 15 1892, Jesse Reno patented his moving stairs or inclined elevator as he called it. In 1895, Jesse Reno created a new novelty ride at Coney Island from his patented design, a moving stairway that elevated passengers on a conveyor belt at a 25 degree angle. Escalator = Scala Elevator The escalator as we know it was later re-designed by Charles Seeberger in 1897, who created the name 'escalator' from the word 'scala', which is Latin for steps and the word 'elevator', which had already been invented. Charles Seeberger, together with the Otis Elevator Company produced the first commercial escalator in 1899 at the Otis factory in Yonkers, N.Y. The Seeberger-Otis wooden escalator won first prize at the Paris 1900 Exposition Universelle in France. Jesse Reno's Coney Island ride success briefly made Jesse Reno into "the" escalator designer and he founded the Reno Electric Stairways and Conveyors company in 1902. Charles Seeberger sold his patent rights for the escalator to the Otis Elevator Company in 1910, who also bought Jesse Reno's escalator patent in 1911. Otis then came to dominate escalator production, and combined and improved the various designs of escalators. According to Otis, "In the 1920s, Otis engineers, led by David Lindquist, combined and improved the Jesse Reno and Charles Seeberger escalator designs, and created the cleated, level steps of the modern escalator in use today. Over the years, Otis dominated the escalator business, but lost the product's trademark. The word escalator lost its proprietary status and its capital "e" in 1950 when the U.S. Patent Office ruled that the word "escalator" had become just a common descriptive term for moving stairways."
