From zygotes to death, evry life event is programmed by genes. The growth of all body tissue. Age of adolescence,( Here is accelaretion of hormones.) age to bear children, Age of maturity. ( Here hormones are stabilised.) Then after reproductin, Nature is not much interested in you. Then changes of old aging start. There is gradual failure of all organs. ( Organs have very large reserve capacity in young age.) Gradually every organ start to get tired and eventually fails. Progeria is a genetic disorder in which a person matures very early and get old very early. All this is programmed by genes. Some trees live for thousands of years. They are programmed by Nature that way. Turtles live for centuries.

What is the connective tissue theory of aging?
The connective tissue theory of aging proposes that changes in the extracellular matrix, such as collagen, elastin, and glycosaminoglycans, contribute to aging. These changes can lead to decreased tissue elasticity, impaired wound healing, and age-related diseases like arthritis. This theory suggests that targeting interventions to preserve or restore the extracellular matrix could potentially slow down the aging process.
Is there a disorder or disease that stops signs of physical aging?
There is no known disorder or disease that completely stops signs of physical aging. However, there are conditions, such as progeria, that can accelerate aging, causing individuals to display characteristics of aging prematurely. Research is ongoing to better understand the genetic and physiological factors that contribute to aging.
What branch of biology deals with the nature of aging?
Gerontology is the branch of biology that deals with the nature of aging, including the study of the biological, psychological, and social aspects of aging.
How do tissues replenish the cells contained within them?
See if this helps you. The historical concept of aging as an irreversible, inevitable, and inefficient biologic status led to the deterministic view of aging, which resulted in the replacement principle of aging control. For this purpose, the replacements of genes, cells, tissues, or organs have been proposed, but without satisfactory results. The novel concept of aging as a responsive and adaptive response to survival has resulted in the development of a new hypothesis of aging; namely, the Gate Theory. The prerequisites of the new hypothesis are gatekeeper molecules and a responsive aging field. Based on this concept, the modulation of gatekeeper molecules affects the cellular aging field, and result in the adjustment of the senescent phenotype. As a candidate for such molecules, caveolin has been examined with respect to its association with the aging phenotype. This new concept proposes the possibility of a restoration principle, which changes our view of aging in the community from simple longevity to a functional longevity. Functional longevity engenders the notions of active participation, positive thinking, and responsible behavior by the elderly. Therefore, it can be suggested that now is the time to accept the restoration principle as a key approach to individual aging control as well as the long live community in substitution with replace principle.

Can eyelashes turn gray as a natural part of the aging process?
Yes, eyelashes can turn gray as a natural part of the aging process.
What is the programmed senescence theory of aging?
The programmed senescence theory suggests that aging is a genetically regulated process designed to limit the lifespan of an organism. It proposes that aging is a result of the activation of specific genes that control the aging process and ultimately lead to the deterioration of cells and tissues over time. This theory contrasts with the idea that aging is simply a result of accumulated damage and wear and tear on the body.
What was The first social theory of aging?
Activity theory was the first social theory of aging, but only after the development of disengagement theory did it receive both its name and recognition as a distinct theory (Hiller & BArrow, 2007).
Wear and tear theory of aging?
The wear and tear theory of aging suggests that the body experiences damage and deterioration over time due to cumulative damage from environmental stressors, leading to the aging process. This theory proposes that the body's cells and systems become less efficient at repairing and maintaining themselves as they age, contributing to the signs of aging and declines in health. However, this theory is not universally accepted, as other factors such as genetics, lifestyle, and metabolic processes also play a role in aging.
What theory of aging suggests that successful adjustment is fostered by a full and active commitment to life?
The activity theory of aging suggests that successful aging is facilitated by staying involved in activities and maintaining social connections. This theory emphasizes the importance of remaining engaged in life to promote well-being and health in older age.
You maintain that physical changes in late adulthood are largely related to built-in-time limits to cell reproduction it's safe to say that you endorse the theory of aging?
Yes, the theory of aging related to built-in time limits to cell reproduction is known as the Hayflick limit theory. It suggests that cells can only divide a certain number of times before reaching a limit, causing physical changes and decline in late adulthood. This theory is one of several explanations for the aging process.
What is the hormonal stress theory of aging?
The hormonal stress theory of aging suggests that the cumulative impact of stress on the hormonal system over time can contribute to the aging process. Chronic stress can lead to an overstimulation of the endocrine system, resulting in an imbalance of hormones that may accelerate aging and increase susceptibility to age-related diseases. Stress management techniques and maintaining hormonal balance may help mitigate this effect.
What is the connective tissue theory of aging?
The connective tissue theory of aging proposes that changes in the extracellular matrix, such as collagen, elastin, and glycosaminoglycans, contribute to aging. These changes can lead to decreased tissue elasticity, impaired wound healing, and age-related diseases like arthritis. This theory suggests that targeting interventions to preserve or restore the extracellular matrix could potentially slow down the aging process.
What is the genetic theory of aging?
The genetic theory of aging suggests that the process of aging is influenced by an individual's genetic makeup. It proposes that variations in genes can affect an organism's lifespan and susceptibility to age-related diseases. Research in this field focuses on identifying specific genes that play a role in the aging process.
What is advantages to the continuity theory of aging?
The continuity theory of aging suggests that individuals maintain or adapt their lifestyles and personalities as they age, leading to a sense of continuity in their lives. This can provide a sense of stability, self-esteem, and purpose, helping individuals navigate the challenges of aging more effectively. It also emphasizes the importance of maintaining social connections and engaging in meaningful activities to support healthy aging.
What movie character was programmed to buy the book The Catcher in the Rye?
Jerry Fletcher from - Conspiracy Theory (1997)
Which sociological perspective is most closely aligned with the disengagement activity and continuity theories of aging?
The functionalist perspective in sociology is most closely aligned with the disengagement and activity theories of aging. Functionalist theory emphasizes the role of institutions in maintaining social order. Both disengagement theory (withdrawal from societal roles) and activity theory (engagement in activities to maintain well-being) examine how individuals adapt to aging in relation to societal expectations and norms.
Shortening of sarcomeres causes?
In biological theory, some biologists suspect the shortening of sacromeres causes aging.
