In fact, friendship can be powerful medicine. There are numerous studies that show strong social support can increase self-esteem, ease anxiety, and improve overall health. More than one-third of adults aged 45 and older feel lonely, and nearly one-fourth of adults over age 65 are socially isolated. While loneliness has long been associated with a decline in mental health, it also poses an increased risk of dementia, heart disease, and stroke. Finding quality friends is an obstacle at any age, but older adults may have a more difficult time. While younger people often find socialization within school and hobbies, older adults may spend their time prioritizing their family or career.
