People with long, thin faces can be left-handed

A new discovery from people with slim, slim faces receives the curious attention of the medical world.

Specifically, a study from scientists at the University of Washington has found that people with long, thin faces are capable of left-handed rates higher than 25%.

The researchers analyzed 13,536 individuals participating in three national surveys in the United States and also found that those with slender faces and structures were involved in overbite - when Clenched teeth, teeth on the teeth are too much, the lower teeth are sunk deep into the alveolar bone and tuberculosis.

About one in five American teens with narrow teeth and previous studies have shown that the incidence of overbite and tuberculosis in humans has a slimmer, slimmer face.

Philippe Hujoel, professor at the School of Dentistry and professor of epidemiology at the School of Public Health, said: "Almost 2,000 years ago, a Greek doctor first identified people with faces. slender as a sign of TB susceptibility and he has correctly identified ' .

Studies in the 20th century confirmed the accuracy and objectivity of his clinical affirmation. In addition, the expression, structure of the face, slender, slender teeth have become a clinical sign for TB birth defects.

At the same time, the Centers for Disease Control and Prevention also showed that this is a sign that the sensitivity of TB risk is very high. The team believes that genetics is very responsible for making facial shapes, and it also increases the risk of tuberculosis and does not exclude the possibility, possibly related to increased ability. Left-handed in these people.

Scientists also said that considering the geographic factor, England is known as the tuberculosis capital of Western Europe, here, the infected people are proportional to the elongated face and most is left handed.
