Conclusion
3. In this topic ‘AGING’ we will know that what
aging actually is and how it occurs. A little bit
of history. Does it occurs in all living beings or
all cells of a multicellular being or just in
particular cells. We will also study that how it
proceeds on or how can we explain the fact
aging. How the aging is optimal? Further more
I'm going to tell that how aging can be slowed
down. And about the life extension and life
extension sciences. At the end we will look
down upon the strategies to lengthen the
cellular life.
7. Life span and the death are all
programmed
A biological clock controls cell behavior
and lifespan
There are specific number of meiosis for
every kind of cell
Some of the cells do not divide and just
age
8. life span of a cell or organism is
genetically determined
The number of repeats in a telomere
determines the maximum life span of a
cell, since each time a cell divides,
multiple repeats are lost. Once telomeres
have been reduced to a certain size, the
cell reaches a crisis point and is
prevented from dividing further
9. Changes in immune system are
responsible for the effects of aging
The system that
produces antibodies loses its ability to
distinguish between “self” and foreign
proteins.
11. Cells are damaged by free radicals
They oxidize DNA
organisms age because cells
accumulate free radical damage over time
12. Mutations are those inheritable changes
that occur in the cellular DNA.
Chromosomes are damaged or the
mutation occurs due to radiation or much
sun exposure
Any change in genetic complement of
somatic cells leads to aging
13. animals and cells, like machines, simply
wear out
however, unlike machines, have some
ability to repair themselves
waste products accumulate within cells
and interfere with function
15. For successful ageing the activities should
be changed
Activities of an individual effect the aging
process
16. Ones behavior also determines the extent
and speed of aging
Thoughts are very important
17. Peoples ways of engaging with a society
effects aging
A lonely person will age faster than others
18.
19. The first formal studies of ageing appear
to be those of Muhammad ibn Yusuf al-
harawi (1582) in his book entitled Ainul
Hayat
20. Optimal aging refers to the fact that if one
is aging properly or not
According to the age of the person
According to physical health
21. No physical disability over the age of 75 as rated
by a physician;
Good subjective health assessment (i.e. good self-
ratings of one's health);
Length of undisabled life;
Good mental health
Objective social support
Self-rated life satisfaction in eight domains, namely
marriage, income-related work, children, friendship
and social contacts, hobbies, community service
activities, religion and recreation/sports.
22. Life extension science, also known as anti-
aging medicine, indefinite life
extension, experimental gerontology,
and biomedical gerontology
the scientific study of the biological,
psychological, and sociological phenomena
associated with old age and aging is called
gerontology
It also includes how to prevent various aging
issues
23. By eating good food
Living happily
Making social
connections
32. Aging is the accumulation of changes in a
person over time. Also it’s a natural
process it cannot be prevented but can be
slowed down by taking care of oneself.
There are a lot of theories being proposed
to explain the process of aging. But none
of them can completely explain the
process.
