"The term refers mainly to humans, many other animals, and fungi, whereas for example, bacteria, perennial plants and some simple animals are potentially biologically immortal."
The gradual changes that occur in an individual's body and mind as they grow older.
Biological aging: The natural decline of physical and mental functions due to the complex processes of cellular, molecular, and systemic changes.
Psychological aging: The intellectual, emotional, and social changes that occur in elderly individuals.
Social gerontology: The study of social and cultural aspects of aging and how they influence an individual's perception of aging.
Health and aging: A study of the physical health of aging individuals and the potential factors that increase longevity and decrease mortality.
Cognitive aging: A study of the changes in cognitive abilities, including memory, attention, language, and problem-solving as one grows old.
Aging and Longevity: A study of biomedical, genetic, and lifestyle factors that influence the longevity in animals and humans.
Aging and Society: Aging and the role it plays in social and societal relations.
Aging and Mental Health: A study of mental illness in elderly people, including depression, anxiety, and dementia.
Aging and Nutrition: A study of how nutrition can affect aging and the lifestyles of elderly people.
Aging and Exercise: A study of how exercise can affect aging and the lifestyles of elderly people.
Aging and Financial Status: A study of how the retirement period affects individuals' financial status.
Aging and Housing: A study of how housing affects the lifestyles of elderly people.
Aging and Relationships: A study of how relationships affect aging and the lifestyles of elderly people.
Aging and End-of-Life Care: A study of caring for aging individuals in their final years of life.
Biological Aging: Refers to the changes that occur in the body's cells, tissues, and organs as a result of natural processes, such as DNA damage, mitochondrial dysfunction, inflammation, oxidative stress, and telomere shortening.
Chronological Aging: Refers to the passage of time since birth and is measured by the calendar age.
Psychological Aging: Refers to the changes that occur in cognition, motivation, emotion, personality, and social interaction as people grow older.
Sociological Aging: Refers to the ways in which social structures, institutions, and practices affect the experience of aging and the status of older adults in society.
Environmental Aging: Refers to the effects of environmental factors, such as pollution, climate change, and exposure to toxic substances, on the health and well-being of older adults.
Cultural Aging: Refers to the ways in which cultural beliefs, values, and practices shape the experience of aging and the attitudes towards older adults in different societies and cultures.
Disengagement Theory: Suggests that as individuals age, they gradually withdraw from society to focus on their own needs and interests, leading to a decrease in social roles and responsibilities.
Activity Theory: Suggests that older adults should strive to maintain an active and engaged lifestyle to promote health and well-being.
Continuity Theory: Suggests that as individuals age, they seek to maintain a consistency between their past and present selves, using the same coping strategies and adapting to changes in their environment.
Successful Aging: Refers to the maintenance of physical, cognitive, and social well-being in old age, characterized by a sense of purpose, autonomy, and life satisfaction.
"In humans, ageing represents the accumulation of changes in a human being over time and can encompass physical, psychological, and social changes."
"Reaction time, for example, may slow with age, while memories and general knowledge typically increase."
"Ageing increases the risk of human diseases such as cancer, Alzheimer's disease, diabetes, cardiovascular disease, stroke and many more."
"Current ageing theories are assigned to the damage concept, whereby the accumulation of damage (such as DNA oxidation) may cause biological systems to fail."
"Programmed ageing should not be confused with programmed cell death (apoptosis)."
"Obesity has been proposed to accelerate ageing."
"Dietary calorie restriction in non-primate animals slows ageing while maintaining good health and body functions."
"In primates (including humans), such life-extending effects remain uncertain."
"For example, bacteria, perennial plants and some simple animals are potentially biologically immortal."
"Of the roughly 150,000 people who die each day across the globe, about two-thirds die from age-related causes."
"The internal processes (epigenetic maintenance such as DNA methylation) inherently may cause ageing."
"Ageing increases the risk of human diseases such as cancer, Alzheimer's disease, diabetes, cardiovascular disease, stroke and many more."
