A majority of people, women in particular, breathe in an illusion that anti-ageing creams or maybe a face-life is the solitary, sure-shot to look young. However, a recently concluded study, which was carried out by researchers from Germany's Max Planck Institute in Berlin, has offered a very surprising alternative for looking much younger than one's actual age.

As per the study, it has been suggested that smile holds the aces when it comes to looking younger than the genuine age of a person. Researchers claimed that the simple deed of smiling can take many years off the actual age of a person. It is expected that we deem that people who are happy are generally attractive in many other ways, like looking younger than what they actually are.

Temporary wrinkles inspired by grinning tends to make it much more dicey to predict the age of a person and so, the researchers believe that it generally provides people a benefit of doubt when someone is guessing their age. As a result, the one who is trying to predict the age will definitely slip up on the lesser side.

During the study, lead researcher Manuel Voelkle questioned more than 150 men and women of dissimilar ages to predict the ages of the faces shown in over 1,000 photographs.

While expressing his opinion regarding the observations of the study, he said: "Facial expressions have a substantial impact on accuracy. Relative to other facial expressions, the age of neutral faces was estimated most accurately, while the ages of those displaying happy expressions was most likely under-estimated".

Besides, the study also claimed that that it is more difficult to judge the actual age of older faces as compared to the younger ones. While judging the age, younger people trimmed a year or two, while elderly people generally overestimated the age of the photographs used during the study.
