Can pretty face play some biological role?
The answer to this question could be found by a group of scientists who researched the correlation between attractiveness and health of a person.
During the experiments 159 photos of real people were shown to almost 500 volunteers who had to choose most attractive faces.
At the same time, the people in the pictures underwent different medical examinations.
As a result, researchers discovered that people whose faces were described as more attractive had on average a better immune system than others did.
This study suggests that attractiveness can have a biological role, signaling the health of the body and the “quality” of heredity.
