    Study Notes

    Body and Mind

    • Grandson's playground visit prompted reflection on ageism and attitudes towards aging
    • Self-deceptive prejudice towards others recognized as ageism
    • Study of later life (65+) explores attitudes, biosocial changes, cognitive aspects (disease, decline, improvement, wisdom)

    Understanding of Old Age

    • Science and baby boom generation both contributed to the change in understanding old age
    • Demography studies populations, showing significant change in age distribution
    • Proportion of older adults (65+) increasing globally, especially in developed nations
    • Average life expectancy has significantly increased globally, more so for low-income nations due to improvements in healthcare, sanitation, nutrition, and newborn care
    • COVID-19 pandemic reduced average life expectancy in the United States for several years
    • Ethnic disparities exist in the impact of the pandemic on average life expectancy.

    What Kind of Old?

    • Different categories of older adults: young-old, old-old, oldest-old
    • Young-old healthiest, most active and independent.
    • Old-old have some physical or mental impairments and need some support
    • Oldest-old require intensive care, live in skilled nursing homes or hospitals, or with family.
    • Ageism in negative perceptions of aging influence actual attitudes and behaviors of older people
    • Ageism exists in expectations/stereotypes of health, behavior, and activity levels that influence the lives of the elderly

    Ageism and Health

    • Ageism in response to COVID-19 affected treatment prioritization in healthcare settings
    • Concerns about overwhelmed healthcare systems in response to aging populations are often exaggerated
    • Older adults spend fewer days in the hospital, on average, than they did in the past
    • Negative stereotypes of older age influence healthcare and social interactions.

    Theories of Aging

    • Wear and tear theory: body wears out from use and environmental factors
    • Cell theory: cellular changes, like shortening telomeres, lead to decline
    • Genetic theory: genes influence lifespan and aging-related factors, including various alleles of the ApoE gene

    Biological Mechanisms

    • Exercise plays a crucial role in maintaining health and well-being for elderly people
    • Calorie restriction studies show that reducing consumption of calories can lead to increase in lifespan
    • Sleep patterns change with aging and there are methods to treat sleep disturbances associated with aging
    • Body systems such as circulatory, digestion and muscle systems are affected by aging and these systems can be compensated for

    Sexuality and Aging

    • There is variation in sexual activity in older adults
    • Attitudes, social norms, and personal circumstances influence sexuality in older adults
    • Preferences and social aspects of sexuality are affected by circumstances beyond biological factors such as culture and traditions
    • Individual differences exist in older people's sexual expression.

    Technology and National Policy

    • Importance of universal design for inclusivity of older populations in modern environments
    • Health challenges with age influence technology choices for older adults
    • Technological tools and societal norms impact aspects of aging such as transportation
    • Policies and cultural norms influence access to healthcare, housing, and other forms of support for older populations

    Conclusion

    • Aging patterns and individual differences affect how older adults experience aging and their overall well-being in society.
    • Acknowledging, combating ageism and embracing diversity in aging are important steps to promoting older adults' overall well-being.
