Hating Red Bull Causes

People often reminded to be careful if adjacent to a bull if wearing a red shirt. Does red bull really make angry? In fact, the bull can not see perfectly, because of partial blindness.
What causes a bull is disturbed, because someone is waving a cloth in her face. View of color is a deceptive subject. In the view of the human eye has a rod that is sensitive to light, but does not provide information about the color. But the bull got, and it works well in dim light or dark.
Like when seen at night, color perception become blurred because of the dark. Stem the human eye is equipped with three types of cone cells, each sensitive to different wavelengths of light, waves of red, green, and blue. Every color that we know, can be represented as a combination of basic colors.
When something goes wrong with the basic view of this aspect, it produces color blindness, which usually form an incomplete inability to distinguish colors, rather than narrow the range of colors that can be felt. Humans have a common view of color as in fish, reptiles, amphibians, and birds. Some animals see more colors than we can, for example bees.
Partial BlindColor perception is the brain's response on the stimulus received by the retina. Has identified three types of cone photoreceptor cells (which needed to be able to distinguish colors) namely blue, green, and red. It takes a minimum of two cells to be able to distinguish colors, and normal color vision is required on all three. Color blindness is usually caused by hereditary factors. Of heredity is the most frequently found are red-green defect cells. Color blindness is associated with X-recessive gene, so descended by the mother (not necessarily having a color blind, because the gene is recessive) to his son. In a person with partial color blindness, may have defects in red or green cone cells so it can not perceive color and its derivatives, is also difficult to distinguish.
Ga bull Cause like red cloth itself because it's actually ga bull like waving the fabric, not the color of the fabric itself. Bull had a disease which he ga partially blind can see the color / color-blind. But as usual emang udah pake matador red cloth as a tool for action against the bull, we consider the red color of the bull who ngebuat ballistic.

10 Ways to Exercise the Brain

Exercise the brain as important as the sports body. With a brain sport, will form new nerve that can protect against dementia or dementia symptoms. Here are some ways you can do to exercise the brain.
Here are 10 ways to train or exercise the brain:

1. Familiarize active as a left-handed (on the left hand) and also the right

Perform tasks with non-dominant hand, if the normally dominant right-handed then use your left hand (lefty) and vice versa. For example when using a computer mouse, brushing teeth and tying shoes in the opposite direction. According to the Franklin Institute, this type of exercise can strengthen the neural connections that exist and even form new nerve.

2. read Reading can flex the muscles of the brain, good light reading (such as comic books or magazines) as well as reading for information. And according to Dr. Nikolaos Scarmeas padaa study in 2001, reading can help build "cognitive reserve" to delay the onset of dementia.

3. Play puzzles or crosswords

Crossword, puzzles, Sudoku puzzles and other types, can train the brain, especially the left hemisphere, according to cognitive training center LearningRx. Add new strategies to effectively exercise the brain, such as solving crossword puzzles with an unusual theme.

4. Play strategy games Strategy games like chess, monopoly or other computer games, will use the right brain that can help people to think more creatively.

5. change routine According to Lawrence Katz, professor of Neurobiology at Duke University Medical Center, changed routines and new ways of living can activate the brain connections that were previously inactive. Exercises can be done for example, bathing with eyes closed or reset your office or desk.

6.learning a foreign language By learning a foreign language will enable parts of the brain that has not been used since you started talking. A 2007 study at York University in Toronto, found that the use of multiple languages ​​can improve the blood supply to the brain to maintain the health of nerve connections.

7. Enjoy the music Besides listening to music, learn also to play a musical instrument. The experts also recommended to enable the two senses at once, such as listening to music and smell the flowers.

8. physical exercise Physical exercise also can improve brain health, because it can increase blood flow to the brain. According to the Stanford Center on Longevity and the Max Planck Institute for Human Development, physical exercise can improve attention, reasoning and memory.

9. social life The brain can be trained with your social life, for example by visiting a friend. A 2006 study by Dr. David Bennett of Rush University Medical Center found that having a social network can provide protection against clinical symptoms of Alzheimer's disease.

Challenge your brain to learn new skills or things you've never done before. If you are not an artist, try to learn to paint or sculpt. If you can play piano, learn to play guitar. Find something new and exciting to be able to keep the brain active.

3 Tree Root Bridge World's Most Unique

The bridge is one of the engineering infrastructure to facilitate the transportation of men. Bridges built on the site over the river, valley, or the sea that separates them. But somewhere in this world, the bridges that connect the rivers were not built, but alive and growing!

1. Root Bridge in India In the depths of south India, in one of the wettest locations on earth, the bridges are made in a very strange and unique.

Growing from the roots of rubber trees, the people Khasis in Cherrapunjee using areca nut tree, splitting it and removing its contents to create what is called "root pointer". When the spread and reach the other side of the river, they began to incorporate them with the roots from the soil. Over time, the bridge is sturdy and life began to take shape.

Root bridges that some in anatarnya reached 30 meters, takes 10 to 15 years to be able to function fully, and make it very sturdy. Some can withstand loads of up to 50 people at once.
One of the most unique structures in Cherrapunjee known as "Umshiang Double-Decker Root Bridge." Bridge consists of two layers, above and below. Because these bridges are still alive and continues to grow, making it more sturdy. Some of the old root bridge has been used every day by people in the villages around Cherrapunjee since more than 500 years ago.
 

2. Bridge vines in the Iya Valley, Japan One of the three valleys of the "hidden", in Japan, West Iya is the place foggy canyon, the river clean, and the roofs of straw or leaves, such as describing the Japanese centuries ago. To cross the river that flows along the Iya valley slopes, the robbers, the kstria, and refugees make a special bridge made of vines. Below is a picture of a bridge of vines in 1880:

First, the two plants Wisteria - one of the most sturdy vines - planted until the very length of both sides of river. When the plants reach a sufficiently long, then woven together with the board to make a living botanical engineering, soft but very sturdy.
Bridges that have no sides, and a source of Japanese history shows that the bridge is unstable plants, and who tried to cross the first time are often frozen in place, unable to proceed further.
Three of these bridges still exist in the valley Yes. Although some (not all) of the bridges were reinforced with wire and strip the sides, it is still scary to cross. More than 42 meters in length, with a board that is placed every 6 to 8 inches, and the fact that one fell into the water from a 4.5 story, making it suitable for people with acrophobia (fear of heights).
Some people believe the bridges that still exist vines was first built in the 12th century, which makes some of the examples in the world's oldest living architecture.

3. Root Bridge in West Sumatra, Indonesia This is now the mainstay attractions of South Coastal District which is one of the most unique bridges in the strong dunia.jembatan and to liaise between the two regions Jorong (Hamlet) and Lubuak Puluik Puluik-Glare, Glare Lubuak Village, Northern District of Bayang, South Coastal District, West Sumatra.
From the information that was summarized a community leader and chairman of the public nature of youth-puluik, Herman Datuak Bandaro Rajo, the bridge was made because of a scholar who was named Pakih Sokan pity to see students from the public nature mengajinya-puluik often do not come because the stream overflowed often stem shadow .

In 1916 Pakih Pohan planted two sticks ox-ox (a type of broad-leaved banyan tree), ox-ox trees were planted at two locations-one in the public nature of puluik and another in the area Lubuak Glare rods separated by shadows. Then the roots are hanging woven bamboo which is used as a bridge as the root bridge of bone. After 3 years the roots of two trees ox-ox are linked but not impassable.
Then Pakih Pohan held mandabiah goat (goat) and mandarai aka (giving blood at the root of that link). "It's a sign of thanksgiving that the ox-ox roots are connected already linked, as a sign of engagement will happen again," added Herman.
To make a bridge that can be passed requiring time for 20 years then the bridge can be taken Puluik-puluik citizens who want to want to Lubuak Glare.
Until now the bridge has a length of 30 meters and 1 meter wide with a height from the surface of the stem shadows about 10 meters and the current age of the bridge is already 93 years and still can be passed from the public nature of citizen-puluik as many as 25 heads of households as well as citizens who want to stricken area -puluik public nature ...
