"The authors of the study, a team led by Dr. Bahman Guyuron of Case Western Reserve University in Cleveland, are plastic surgeons who study faces for a living. They analyzed photographs of the faces of 186 pairs of identical twins taken at the Twins Days Festival, a sort of twins' pride event held every summer in (naturally) Twinsburg, Ohio."
"In this study, we looked at identical twins because they are
genetically programmed to age exactly the same, and in doing so we
essentially discovered that, when it comes to your face, it is possible
to cheat your biological clock," said Guyuron.
Researches studied photos of 186 pair of identical twins.
According to the study:
In those sets of twins who were less than 40 years old, the heavier
twin was perceived as being older, while in those groups over 40 years
old, the heavier twin appeared younger."
The study also showed that twins who had been divorced looked 2 years older as opposed to those who had not been divorced.
"The presence of stress could be one of the common denominators in those twins who appeared older," said Guyuron.
