What Old Means?
Do not be afraid of being old. Many positive things can always be done. The question is how to deal comfortably.
Everybody wants to live longer, but nobody wants to be or look old. This phenomenon has happened today. Every kind of how they are made, the more rational and even more illogical to cover the signs of aging.
What is old?
Old or more commonly known now as aging is a natural process and just signed by a decrease in biological function and fertility lower and also by increasing mortality and accumulation of age. Aging process is initiated by sexual maturation continued and when he reached the maximum age (duration / life). Death is the last event of the aging process.
We can also say that aging is the loss of functionality and performance of the system organ in the body, causing a decline in the ability of the body reserves so that eventually cause death.
It ‘hard to distinguish whether the aging process is a kind of disease or biological symptoms. In other words, is primary (the problem is caused by itself) or secondary (effect of or related to other processes).
In terms of biological aging is a universal rule that has happened to all types of creatures. Each creature gets old before it’s time of death. If someone becomes ever larger, he / she becomes easily infected by disease and organ failure. So, to stop the aging process, people must be able to stop the body’s sensitivity to the disease and end organ deterioration.
Aging indicators.
There are some indicators or biomarkers of aging. These indicators are not only appreciated by physical appearance or external, such as gray hair, decreased memory (dementia), or susceptibility to disease. Are also indicated by biochemical and cellular chromosome process.If end of the polymer is becoming increasingly shorter, and the replication of the chromosome is not renewed, it means that the aging process has already happened.
Process that occurs when a person grows older
There are several theories regarding the aging process. In all, the theory of free radicals is the main and the most logical theory that can explain the aging, although aging is associated with functional and structural changes that have occurred, as implicit old.
Free radical theory says that the signs of aging throughout the body including the brain are caused by damage to cells that have taken place due to free radicals (unstable molecules react with oxygen). Free radicals generating oxidative damage to cells. The oxidation process will destroy the mitochondria, the powerhouse in a cell. This problem becomes more serious, because the mitochondria expels amounts of free radicals when it produces energy. Therefore, the cellular damage is even worse, and is expressed in many signs of aging.
Another theory is that aging occurs because of damage damage.The body protein occurs because the protein is chemically linked with the sugar. The latest theory is the theory of telomeres compression. When a cell divides into two (reproduction), not the end of the telomeres shorten, until it stops, the growth of cells to abstain. www.waytobehealth.com.
