How does the scientific "physiognomy" identification technology predict life?

Reference News Network reported on July 4 that foreign media said that researchers are studying a new technology to predict people's life span by observing the aging speed of human faces.

On July 2nd, Washington post website published an article entitled "How long can your face reflect your life? Imagine that an insurance salesman comes to your home, records your weight and blood pressure, and takes a snapshot of your face. When the information of wrinkles, spots and loose parts of the face is input into the computer, you can predict how long you will live.

Facial recognition technology has been used to search for criminals and guess the appearance of missing children as adults, but it will soon be used for private purposes. Some scientists are developing a life analysis system based on the speed of facial aging.

Jay Olysansky, a biostatistician at the University of Illinois, said: "We know that some people age faster than others in the process of getting old. We also know that the descendants of people with slow aging tend to live longer than others. "

Olysanski said that the research is still in its infancy, but the idea of using face recognition technology has aroused the interest of insurance company executives, who saw the potential of using this technology to determine insurance premiums.

This technology includes using a computer to scan facial photos to record signs of aging. In addition to considering all factors that affect life expectancy, such as race, gender, education level and smoking history, the computer will also analyze the changes of the subjects' cheeks, eyes, forehead, mouth and jaw. Compared with other people of the same age and background, wrinkles, spots, sagging and other changes related to aging can show the aging degree of the subjects.

Olshanski has to admit that even if facial aging is related to longevity, there are still some people who don't apply this conventional model. He said that the oldest person in the world has been smoking for 100 years, and the president of the United States is often an exception. They are very old when they are in office, but they usually live longer than the average person.

But he said that for most people, the face is a window to the health of the whole human body. He said: "The face can capture many health risk factors, such as smoking (wrinkles will appear around the corners of the mouth), excessive drinking (enlarged nose), sun exposure and excessive stress (brown spots and wrinkles will appear in advance)."

But at least, understanding the analysis results of facial aging may attract participants' attention and try to prolong their life by developing good habits.
