2. Hallmarks of aging - Wikipedia

   en.wikipedia.org/wiki/Hallmarks_of_aging

   Aging is characterized by a progressive loss of physiological integrity, leading to impaired function and increased vulnerability to death. The hallmarks of aging are the types of biochemical changes that occur in all organisms that experience biological aging and lead to a progressive loss of physiological integrity, impaired function and, eventually, death.

3. Biomarkers of aging - Wikipedia

   en.wikipedia.org/wiki/Biomarkers_of_aging

   The main mechanisms identified as potential biomarkers of aging are DNA methylation, loss of histones, and histone modification. The uses for biomarkers of aging are ubiquitous and identifying a physical parameter of biological aging would allow humans to determine our true age, mortality, and morbidity. [10]

4. Evolution of ageing - Wikipedia

   en.wikipedia.org/wiki/Evolution_of_ageing

   Williams noted that senescence may be causing many deaths even if animals are not 'dying of old age.' [1] He began his hypothesis with the idea that ageing can cause earlier senescence due to the competitive nature of life. Even a small amount of ageing can be fatal; hence natural selection does indeed care and ageing is not cost-free.

5. Ageing - Wikipedia

   en.wikipedia.org/wiki/Ageing

   In the field of sociology and mental health, ageing is seen in five different views: ageing as maturity, ageing as decline, ageing as a life-cycle event, ageing as generation, and ageing as survival. [126] Positive correlates with ageing often include economics, employment, marriage, children, education, and sense of control, as well as many ...

6. Aging-associated diseases - Wikipedia

   en.wikipedia.org/wiki/Aging-associated_diseases

   An aging-associated disease (commonly termed age-related disease, ARD) is a disease that is most often seen with increasing frequency with increasing senescence. They are essentially complications of senescence, distinguished from the aging process itself because all adult animals age ( with rare exceptions ) but not all adult animals ...

7. Free-radical theory of aging - Wikipedia

   en.wikipedia.org/wiki/Free-radical_theory_of_aging

   Brewer proposed a theory which integrates the free radical theory of aging with the insulin signalling effects in aging. [36] Brewer's theory suggests "sedentary behaviour associated with age triggers an oxidized redox shift and impaired mitochondrial function". [36] This mitochondrial impairment leads to more sedentary behaviour and ...

8. Old age - Wikipedia

   en.wikipedia.org/wiki/Old_age

   Old age is the range of ages for people nearing and surpassing life expectancy. People who are of old age are also referred to as: old people, elderly, elders, senior citizens, seniors or older adults. [1] Old age is not a definite biological stage: the chronological age denoted as "old age" varies culturally and historically. [2]

9. Cardiology - Wikipedia

   en.wikipedia.org/wiki/Cardiology

   Preventive cardiology also deals with routine preventive checkup though noninvasive tests, specifically electrocardiography, fasegraphy, stress tests, lipid profile and general physical examination to detect any cardiovascular diseases at an early age, while cardiac rehabilitation is the upcoming branch of cardiology which helps a person regain ...
