UMKC study says smiling helps you look younger and thinner
KANSAS CITY, Mo. (AP) — Recent research from the University of Missouri-Kansas City suggests smiling may make you appear younger and thinner.
The Kansas City Star reports that research from the university's psychology department shows that when you smile, other people tend to see you as younger than if you are staring back with a neutral expression or frown. And if you frown, you look heavier.
The age perception research was recently published, and found that no matter the age group, happy, smiling faces were judged as "young" far more often than faces with neutral expressions. Neutral faces were seen as older in each age group than their happy counterparts.
Another recent UMKC study also showed that sad faces were judged by people as being heavier.
