period of retirement ( Yao et al., 2020 ), often at a much younger age relative to the general working population (e.g., retirement age in Japan is early 60s, and professional athletes tend to be mid- to late 30s). Despite this age difference, athletic retirement has been analogously compared with work

adults aged 60 years and older may jump to 21.4%, which is more than double their current percentage. In the case of Japan, the older adults (60 years and older) portion of the population rose from 18% in 1980 and is estimated to rise to approximately 34% by 2030 ( Auerbach, Kotlikoff, Hagemann

Few epidemiological studies have examined the potential protective effects of physical activity on insomnia. The authors thus evaluated the association between physical activity and insomnia in a large population-based study in Shizuoka, Japan. Individual data were obtained from participants in an ongoing cohort study. A total of 14,001 older residents who completed questionnaires were followed for 3 yr. Of these, 10,211 and 3,697 participants were eligible for the cross-sectional and longitudinal analyses, respectively. The authors obtained information about the frequency of physical activity and insomnia. Then, the adjusted odds ratios and 95% confidence intervals between physical activity and insomnia were estimated. Habitual physical activity was related to lower prevalence of insomnia. Frequent physical activity also reduced the incidence of insomnia, especially difficulty maintaining sleep. For elderly people with sufficient mobility and no preexisting disease, high-frequency physical activity (e.g., 5 or more days/wk) may help reduce insomnia.

To explore successful aging and high social activity in old age, data from a self-administered survey of 5,239 participants aged 65 years or more were analyzed. The questionnaire inquired about physical conditions and lifestyles of Japanese seniors during middle age and their present social activities in 4 regions of Japan in 1993. The authors first defined social activities and then developed a social-activity measure. Next, they examined the association between present social activity and physical conditions and lifestyles during middle age. Data analysis revealed that the most socially active seniors rated themselves as healthy and physically active during middle age. Socially active seniors differed from less active seniors: They had participated in more hobbies during middle age, had higher levels of education, and had had a more varied diet between the ages of 30 and 50. The data suggest that maintaining general health habits and lifestyles from middle age on is important for successful aging and high social activity in old age.
