Why does a person get old ?
In the eyes of Islam and science
Allah is the One who created you and kills you, and turns some of you to a useless age (old age) so that even knowing everything, you do not know. Indeed, Allah is All-Knowing and All-Powerful. Surah Al-Nahl verse 70 in the eyes of science
Branch of Biology
"Gerontology"
Relates to what we commonly call aging in a very simple sense.
First of all, the definition of old age should be understood, what is old age or "aging".
Aging can be defined as changes in physical or physical characteristics that occur in all living organisms but its order and principles are common to all people.
It is also possible that its rate is low in some people and high in some people, so a significant difference can be found
Due to old age/reasons
First of all, science has identified two main reasons for this
Science of genetics/heredity
The secret code of aging lies in our DNA molecule which causes aging at any given stage (if you are a science student). As the cell divides itself, it becomes very slow and present in the cell
"Telomeres"
The size of the cells decreases which eventually leads to aging
"Mitosis"
The process of division by division is found to be the driving force behind this whole process.
We call this the first reason
"Primary Cause Of Aging"
say
As DNA becomes damaged during aging.
Changes in the membranes and enzymes around the cell. Disruption of delivery system or
"Malformation In Transport System Of Ions & Nutrients
etc. Many changes in the chromosomes lying in the nucleus of the cell eg
Fragmentation, Shrinkage , Clumping
Included
Environmental elements/factors and their effects
The environment of any organism is considered to be its environment which consists of both living and non-living things.
Environment is considered a secondary cause of aging.
A great example of which is that you can best replicate this experiment by placing two twins in two different environments to see who ages early and who ages late, but this secondary cause is preventable ie.
"Preventable"
And primary reason number (a) is beyond our control
The process/method of aging or aging
Its simple definition is that the gradual changes in physical characteristics are called aging or "aging", which is positively identified with the loss of organs over time and the progressive decline in the musculoskeletal system and their functions. Slow down or slow down
Signs of aging
First is energy depletion
Changes in sleep
Loss of memory
Skin and hair changes such as wrinkles
Halos around the eyes
Brown marks on the skin
Loss of elasticity in the skin
Loss of hearing and vision
Sexual infertility
Problems with small urination
Menstruation or changes in menstrual periods
Abdominal enlargement and inability to lose weight
Not exercising
smoking
Excess of fat
etc. are the main symptoms
hint
We can prevent the secondary causes of aging by using creams etc. but we are powerles
