About one in ten thousand people born with mirrored arrangement hanachu of internal organs: heart, stomach and spleen are located right at it, and liver and gallbladder - left. These people are more common heart defects, but most lead a normal life and often not even aware of their features.

For this reason, many surgeons hanachu use it as material for tissue repair other damaged muscles.
Dream of the common man is 7-8 hours a day, but in the presence of mutations in the gene hDEC2, regulating the sleep-wake cycle, the need for sleep can be reduced to 4 hours. hanachu Carriers of this mutation is due to the additional time often achieve more in life and career.

Japanese scientists led by Tamami Nakano found that people often do not blink at random times, and at the conclusion of an event - for example, in the end of a sentence when reading companion during a pause or change the scene in the movie. Study using computed tomography showed that in such moments of blinking in the brain activity of a neural network plummets attention and the brain goes into "passive mode". This may indicate that our frequent blinking resets attention and "reset" a responsibility in nerve cells.
Many people, cut paper, experiencing much more severe pain than when cut with a knife. This is because the cut paper generally shallow and there is allocated enough blood or not it is released hanachu completely, leaving the closure exposed to nerve irritation air. If cut deep, in the course are other factors: first, the heterogeneous structure of the paper is rough skin causes microscopic lesions more than flat edge of a knife, and second, additional irritation caused by chemical hanachu substances that are impregnated paper fibers.
