This study investigates how age and mental experience affect psychological factors, and how this, in turn, impacts the community. Our aim is to examine how life expectancy, resilience, and locus of control vary across different age groups. We recruited 382 male and female students from Tehran as participants, using a causal-comparative design. The research involved the administration of three separate questionnaires. Our data analysis, conducted at both descriptive and inferential levels, revealed some interesting findings. The results indicate a significant correlation between subjective age categories (younger, equal, and older than the birth certificate age) and variations in life expectancy, resilience, and locus of control.
