The authors conducted a study of 422 women, ages 31 to 77 years, to explore the relationships among friendship networks, subjective age, and life satisfaction. Friendship network size was related to lower subjective age but not to chronological age. More frequent visits with friends were related to lower subjective age and to higher life satisfaction. Satisfaction with the number of friends and a larger number of friends were related to higher levels of life satisfaction. Subjective age, group belonging, and being someone's best friend were significant predictors of life satisfaction.
