When it comes to getting a look of your youth, people need to look no further than your face.
Researchers at the University of Edinburgh have learned that one from about one's childhood can find by looking at the symmetry of a person's face, the UK's the Telegraph reported.
"Symmetry in the face is considered a marker of what's called developmental stability-ability of the body to resist environmental stressors (stressors) and not be knocked the development path. We were wondering if face symmetry either the stressors faint in early life, that we may be particularly important record would, or the total accumulated effects of stressors through the life cycle, "said Professor Ian Deary of the University of Edinburgh Psychology Department of centre of cognitive aging.
One of the first findings was that people with disabilities were on had deprived childhoods asymmetric faces more likely than those with symmetrical faces.
"The results indicated that deprivation in early life that some impression on the face. The Association is not very strong, which means that other things also face symmetry also affect, "he added.
The Telegraph said the researchers found the symmetry of faces give early childhood experiences such as nutrition, illness, exposure to pollution and other signs of a hard upbringing.
These features are displayed, even if one is a rags-to-riches change, the study found.
In their study published in the journal economics and human biology, the scientists suggested facial symmetry can be used with other medical markers such as hypertension to identify people who might be at an increased risk of disease.
But expensive said there was still a lot of work before it can be used like this. "It is a measure based on research and quite tricky to figure out at this time," he said.
292 topics
Deary and his colleagues examined the facial features of 292 83-year-old people who participated in the Lothian 1921 Birth Cohort. The study followed the participants through their lives.
The researchers compared the facial symmetry of the participants with details of their social status at the youth, including their "parents occupation, how crowded their house was and whether they had a indoor or outdoor toilet."
Also, they looked at 15 different facial features, including the positions of the eyes, nose, mouth and ears.
What they found was a "strong association between social class and the symmetry of the face in men", said The Telegraph.
But the results in women were not as clear.
"A small link of parental status face symmetry does not mean people are trapped by their circumstances. Far from it-as evidenced by the high levels of mobility in society, not only people like Gordon Ramsay, but to a lesser extent by millions of people, "said Professor Tim Bates, who co-authored the study
Attraction
The associated press also said the link between facial symmetry and exposure to stress in early life may help to explain why many studies found that people with a symmetrical face attractive.
"Unbalanced facial features can be a signal that a person is less desirable as a degree due to the stress they experienced in early life that could them vulnerable to disease and early death unconscious," said it. — TJD, GMA News
