Psychology research links successful aging to social selectivity

Psychological research suggests that successful aging at age 70 is often characterized by social selectivity rather than high levels of activity. According to the socio-emotional selectivity theory developed by Stanford psychologist Laura Carstensen, as individuals perceive their remaining time to be shorter, they tend to prioritize relationships with deep emotional meaning over a large number of casual acquaintances.

A 2014 study in the International Journal of Behavioral Development noted that while close friendship circles remain relatively stable, the number of distant acquaintances typically decreases.

Other contributing factors to biological age and healthy aging include regular sleep and activity patterns, as well as genetic factors related to muscle repair. A Pew Research report indicates that nearly half of Americans over 65 report aging well, citing health, financial security, and social support as critical elements.
