An Elderly Grandfather Does Not Get Out as Much as He

An elderly grandfather does not get out as much as he formerly did. Although he is healthy and still drives, he tends to associate with family and a few close friends, whereas in the past, he was busy with social activities. He seems satisfied with his life, but his family is worried that his social circle is too limited and that he may be unhappy yet unwilling to talk about his unhappiness. Discuss briefly the cognitive, social, and emotional changes that occur in later adulthood.
