paragraph_text: Older adults
  
  Older adults report high levels of personal satisfaction in their friendships as they age, even as the overall number of friends tends to decline. This satisfaction is associated with an increased ability to accomplish activities of daily living, as well as a reduced decline in cognitive abilities, decreased instances of hospitalization, and better outcomes related to rehabilitation. The overall number of reported friends in later life may be mediated by increased lucidity, better speech and vision, and marital status. A decline in the number of friends an individual has as they become older has been explained by Carstensen's Socioemotional Selectivity Theory, which describes a change in motivation that adults experience when socializing. The theory states that an increase in age is characterized by a shift from information-gathering to emotional regulation; in order to maintain positive emotions, older adults restrict their social groups to those with whom they share an emotional bond. As one review phrased it:
  
  Research within the past four decades has now consistently found that older adults reporting the highest levels of happiness and general well being also report strong, close ties to numerous friends.
  
  As family responsibilities and vocational pressures lessen, friendships become more important. Among the elderly, friendships can provide links to the larger community, serve as a protective factor against depression and loneliness, and compensate for potential losses in social support previously given by family members. Especially for people who cannot go out as often, interactions with friends allow for continued societal interaction. Additionally, older adults in declining health who remain in contact with friends show improved psychological well-being.
