_____ l Adolescents and old people are both often segregated from the rest of society: young people are isolated in schools, and many old people in retirement communities, assisted-living facilities, and nursing homes. 2 Also, both groups tend to be poorer than young adults or middle-aged people: adolescents because they do not yet have the education or experience to command high salaries, and old people because they are retired and living on their savings and social security. 3 Third, independence is important for both groups---they are conscious of wanting it, whereas young adults and middle-aged people take it for granted. 4 Adolescents want to become independent of their parents; old people want to keep their independence and not have to rely on their children or on social institutions. 5 Fourth, they both tend to have a relatively large amount of leisure time or, at least, time that they can choose or not choose to fill with study or work. 6 By contrast, young and middle-aged adults typically spend most of their time at their jobs or taking care of home duties such as child-rearing.
