Does looking younger than one's age means longer life?

According to a new study, people who look younger than their age tend to live longer than those who look older than their years. The research also found that perceived age was significantly associated with survival, even after adjustments were made for actual age, sex and the environment in which each pair of twins was raised. The bigger the difference in perceived age, the more likely it was that the older-looking twin died first.

The research also said the relation between association between perceived age and physical and mental functioning and common genetic factors influencing both survival and perceived age.

I just want to ask you people, do you also believe that looking younger than one's age means in longer life?
