Face scans show how fast a person is aging
Aging is an unavoidable process. No organism can escape from this process. Recognition of aging process by wisdom and experience is a common phenomenon by scientifically is yet to be standardized. With the help of digitalization it is not impossible. According to research published in cell research on March 31st 2015, aging process can be recognize by computer using 3D facial recognition technology.
Scientists from China led by Weiyang Chen identified some characters like facial shape, nose tip, nose width, mouth width, angles of eyelids, slope of eye, asymmetry between slopes of eye, thickness of upper and lower lips and variation in thickness of lips, distance between lips and nose, etc. as the parameter for facial recognition for aging.
There are many changes exhibited in these average faces, especially in the mouth, nose and eye regions. From young adulthood to old age, the mouth elongates, the nose becomes wider, the mouth-nose distance increases and eye corners droop. Young faces are smoother and thinner than old faces; old faces have more face sagging, subcutaneous fat accumulation and fuller cheeks than young faces. Overall, our reconstructed average face profiles reflect the general patterns of facial aging.
Scientists connected change in face as one factor and compared it with age related blood profiles through biochemical test. They concluded that, despite a close relationship between facial morphological features and health indicators in the blood, facial features are more reliable aging biomarkers than blood profiles and can better reflect the general health status than chronological age.
