“…These life stage differences translate into variance in how older, versus younger, people spend their time. Older people, on average, have more free (leisure) time during retirement (Cowgill & Baulch, 1962; Krantz-Kent & Stewart, 2007), spend greater amounts of time volunteering than most younger age groups (Kaskie, Imhof, Cavanaugh, & Culp, 2008; Wilson, 2000), spend less time doing housework (Rexroat & Shehan, 1987; Verbrugge, Gruber-Baldini, & Fozard, 1996), and have more frequent interruptions to night sleep (Ceolim & Menna-Berreto, 2000; Yoon et al, 2003) which likely leads to more time resting during the day, as Horgas, Wilms, & Baltes (1998) find. Younger people, on the other hand, tend to eat out more (Presser, 1999), spend more time at work and in school (Keller, 2001; Nyce, 2007), and take fewer daytime naps (Buysse et al, 1992), than their older compatriots.…”
