Brown Eyes vs Other Colored Eyes

"The only difference between brown eyes and every other colored eye is that brown eyes have more pigment."

Animals Which sleep on their back.....

"The only animals that can naturally sleep on their backs are humans. No other animal actually does--apes usually sleep sitting up and leaning on something."

Origin of Salute....

"The military salute originated during the medieval times. Knights in armour used to raise their visors to reveal their identity, and the motion later evolved into the modern-day salute."

A salute (also called obeisance) is a gesture (often a finger gesture) or other action used to display respect. Salutes are primarily associated with armed forces, but other organizations and civil people also use salutes.

The exact origin of this salute has been lost to time. One theory is that it came from Roman soldiers' shading their eyes from the intense light that was pretended to shine from the eyes of their superiors. Another theory is that it came from when men-at-arms wore armour—a friendly approach would include holding the reins of the horse with the left hand while raising the visor of the helmet with the right, so that one would know they meant not to battle them. A third theory is that the salute, and the handshake, came from a way of showing that the right hand (the fighting hand) was not concealing a weapon. A combination of showing an empty right hand, palm outwards, which was then raised formally to a helmet to raise a visor would demonstrate non-aggressive intentions, and therefore respect. In Tudor times the helmet of a suit of armour was known as a 'sallet', a word very similar to the word 'salute'.

Shell Company - Origin

"The Shell Oil Company originally began as a novelty shop in London that sold seashells."

The name Shell is linked to the Shell Transport and Trading Company. In 1833, the founder's father, also Marcus Samuel, founded an import business to sell seashells to London collectors. When collecting seashell specimens in the Caspian Sea area in 1892, the younger Samuel realized there was potential in exporting lamp oil from the region and commissioned the world's first purpose-built oil tanker, the Murex (Latin for a type of snail shell), to enter this market; by 1907 the company had a fleet. Although for several decades the company had a refinery at Shell Haven on the Thames, there is no evidence of this having provided the name.

Human Nostrils....Smell

"Each nostril of a human being registers smells in a different way. Smells that are made from the right nostril are more pleasant than the left. However, smells can be detected more accurately when made by the left nostril."

A nostril (or naris, pl. nares) is one of the two channels of the nose, from the point where they bifurcate to the external opening. In birds and mammals, they contain branched bones or cartilages called turbinates, whose function is to warm air on inhalation and remove moisture on exhalation. Fish do not breathe through their noses, but they do have two small holes used for smelling which may be called nostrils.

The Procellariiformes are distinguished from other birds by having tubular extensions of their nostrils.

In humans, the nasal cycle is the normal ultradian cycle of each nostril's blood vessels becoming engorged in swelling, then shrinking. During the course of a day, they will switch over approximately every four hours or so, meaning that only one nostril is used at any one time. The nostrils are separated by the septum.

Flamingos -- eats heads high.....

 

"A flamingo can eat only when its head is upside down."

Flamingos or flamingoesare gregarious wading birds in the genus Phoenicopterus, the only genus in the family Phoenicopteridae. There are four flamingo species in the Americas and two species in the Old World.

Flamingoes are well attested in the fossil record, with the first unequivocal member of the extant family Phoenicopteridae, Elornis known from the Late Eocene. A considerable number of little-known birds from the Late Cretaceous onwards are sometimes considered to be flamingo ancestors. These include the genera Torotix, Scaniornis, Gallornis, Agnopterus, Tiliornis, Juncitarsus and Kashinia; these show a mix of characters and are fairly plesiomorphic in comparison to modern birds.

Kiwi - Hunting

 

"KIWIS are the only birds, which hunt by sense of smell."

Kiwi are flightless birds endemic to New Zealand, in the genus Apteryx and family Apterygidae.
At around the size of a domestic chicken, kiwi are by far the smallest living ratites and lay the largest egg in relation to their body size. There are five recognised species, all of which are endangered.
The kiwi is a national symbol of New Zealand.

OSTRICH - Digestion....

"OSTRICH eats pebbles to help digestion by grinding up the ingested food."

The Ostrich, Struthio camelus, is a large flightless bird native to Africa. It is the only living species of its family, Struthionidae and its genus, Struthio. Ostriches share the order Struthioniformes with the kiwis, Emus, and other ratites. It is distinctive in its appearance, with a long neck and legs and the ability to run at maximum speeds of about 70 km/h (45 mph), the top land speed of any bird.[3]largest living species of bird and lays the largest egg of any living bird (extinct elephant birds of Madagascar and giant moa of New Zealand laid larger eggs). The Ostrich is the

Dolphins - Sleep

 

"DOLPHINS sleep with 1 eye open."

 

Dolphins are marine mammals that are closely related to whales and porpoises. There are almost forty species of dolphin in seventeen genera. They vary in size from 1.2 m (4 ft) and 40 kg (90 lb) (Maui's Dolphin), up to 9.5 m (30 ft) and 10 tonnes (9.8 LT; 11 ST) (the Orca or Killer Whale). They are found worldwide, mostly in the shallower seas of the continental shelves, and are carnivores, mostly eating fish and squid. The family Delphinidae is the largest in the Cetacean order, and relatively recent: dolphins evolved about ten million years ago, during the Miocene. Dolphins are among the most intelligent animals and their often friendly appearance and seemingly playful attitude have made them popular in human culture.

Countries which do not follow Metric System...

"United States and Burma are the only countries that do not use the metric system for their principal units of measurement".

Blood Cell Circulation....in body

"An individual blood cell takes about 60 seconds to make a complete circuit of the body."

A blood cell (also called blood corpuscle) is any cell of any type normally found in blood. In mammals, these fall into three general categories: 

red blood cells — Erythrocytes 

white blood cells — Leukocytes 

platelets — Thrombocytes 

Together, these three kinds of blood cells sum up for a total 45% of blood tissue by volume (55% is plasma). This is called the hematocrit and can be determined by centrifuge or flow cytometry.

Lack of Sleep - Death

"A person will die from total lack of sleep sooner than from starvation. Death will occur about 10 days without sleep, while starvation takes a few weeks."

Cough - Spped

"A cough releases an explosive charge of air that moves at speeds up to 60 mph."

A cough, in medicine, is a sudden and often repetitively occurring defense reflex which helps to clear the large breathing passages from excess secretions, irritants, foreign particles and microbes. The cough reflex consists of three phases: an inhalation, a forced exhalation against a closed glottis, and a violent release of air from the lungs following opening of the glottis, usually accompanied by a distinctive sound. Coughing can happen voluntarily as well as involuntarily, though for the most part it is involuntarily.

A cough is a protective, primitive reflex in healthy individuals, and thus can occur while a person is unconscious. The cough reflex is initiated by stimulation of two different classes of afferent nerves, namely the myelinated rapidly adapting receptors, and nonmyelinated C-fibers with endings in the lungs.
