* The Main Library at Indiana University sinks over an inch every year because when it was built, engineers failed to take into account the weight of all the books that would occupy the building.
* Our eyes are always the same size from birth, but our nose and ears never stop growing.
* Americans on average eat 18 acres of pizza every day.
* Every year over one million earthquakes shake the Earth.
* If our Sun were just inch in diameter, the nearest star would be 445 miles away.
* Without its lining of mucus your stomach would digest itself.
* Each person sheds 40lbs of skin in his or her lifetime.
* The grey whale migrates 12,500 miles from the Artic to Mexico and back every year.
* After the invention of the transistor in 1947, several US electronics companies rejected the idea of a portable radio. Apparently it was thought nobody would want to carry a radio around. When Bell put the transistor on the market in 1952 they had few takers apart from a small japanese start-up called Sony. They introduced the transistor radio in 1954.
* In 1954, a concert manager fired Elvis Presley, saying, “You ought to go back to driving a truck.” In 1962, Decca Records rejected the Beatles, “We don’t like their sound, and guitar music is on the way out.”
* That Sharks apparently are the only animals that never get sick. They are immune to every type of disease including cancer.
* That americans throw away 2.5 million plastic bottles every hour.
* That glass produced from recycled glass instead of raw materials reduces related air pollution by 20%, and water pollution by 50%.
* Although a cow has no upper front teeth, it grazes up to 8 hours a day, taking in about 45 kg (100 lb) of feed and the equivalent of a bath tub full of water. A healthy cow gives about 200,000 glasses of milk in her lifetime.
* The average lifespan of a cow is 7 years. The oldest cow ever recorded was Big Bertha. She reached 48 in 1993. She also holds the record for producing 39 calves.
* Cows release some 100 million tons of hydrocarbon annually – by releasing gas.
* An elephant’s brain weighs 5000g (176oz or 11 lb), a whale’s 10000g (352oz or 22lb). In proportion to the body, the whale has a much smaller brain than man. This seem to give man the edge, until it was discovered that the dwarf monkey has 1g of brain per 27g (0.95oz) of body, and the capuchin monkey has 1g of brain per 17,5g body, whereas man has 1 gram of brain to 44g of body.
* The human brains consists of more than 100 billion neurons (nerve cells) through which the brain’s commands are sent in the form of electric pulses. These pulses travel at more than 400 km/h (250 mph), creating enough electricity to power a lightbulb. The brain consumes more energy than any other organ, burning up a whopping one-fifth of the food we take in.
