Life expectancy linked to unexpected factor
American researchers have identified a statistical link between physical attractiveness and life expectancy. Analysis of data from over 8,300 Wisconsin high school graduates showed that the least attractive men live on average one year less, and women two years less. A causal relationship has not been proven.
Researchers from Arizona State University and the University of Texas at Austin published a study in the journal Social Science & Medicine that found a statistical association between physical attractiveness and life expectancy. The study was based on data from over 8,300 Wisconsin high school graduates who were followed for approximately 65 years. Scientists used old photographs of participants, rated by independent evaluators, and compared these ratings with mortality data. The most notable differences were found among those deemed least attractive: men in this group lived on average one year less, women two years less. The researchers emphasize that the study identified a correlation, not a causal relationship. Possible explanations include links between appearance and health status, as well as social advantages that attractiveness may confer in professional and personal life. Biological and genetic factors are also considered. The study has limitations: attractiveness ratings are subjective and depend on cultural norms, and the sample is limited to one generation and one U.S. region.
