Why do we age? A new theory scientists

If a careful observer will look at our society from the outside, you will certainly notice the widespread obsession with anti-aging. According to experts, the market of anti-aging agents within the next five years will reach 271 billion dollars. Today consumers enjoy a variety of anti wrinkle, including hair restoration, their colors, and numerous beauty treatments. In the future, such goods and services will become even greater. At the same time, so popular creams and anti-wrinkle focused primarily on the external aspects of aging and eliminate only the symptoms, rather than internal key factors of aging. But what science knows about aging?

Perhaps in the future we will be able to defeat aging

Based on what the popular theory of aging?

Researchers have proposed numerous theories of aging with the appearance of two main categories: programmed theories of aging and the theory of errors in DNA. Programmable theory based on the idea that aging is genetically programmed into the body and may be a by-product of reproductive considerations. The theory of errors is based on the concept that dysfunction of metabolic pathways and accumulation of metabolic byproducts such as reactive oxygen species (ROS) or free radicals gradually impair cellular and tissue structures of the body, which leads to potential loss of vital functions.

To better understand the theory of aging, we recall an integral part of evolution by natural selection. It is no secret that each of us has a phenotype of certain genetic characteristics, which can vary due to genetic mutations. Some mutations do not affect us, unlike other. Good mutations are passed to future generations, the bad will disappear.

Some people can’t deal with their own aging

However, many genetic diseases still exist. Experts believe that the fact that some mutations which lead to the development of diseases in older age, can have a positive effect on the body at an early age. So, a great example is the gene mutation causing Huntington’s disease. They improve fertility, reduce risk of cancer and protect against malaria. Also mutations associated with cystic fibrosis improve fertility. And these are just some examples of many. Thus, our knowledge about aging is based, as described above, on two main theories. But we moved scholars forward in the study of the nature of aging?

A new theory of aging

In 2006, scientists put forward new theory. According to her, we age because of the activity of certain proteins and genes responsible for their creation. The role of these proteins is to let the body cells if nutrients. However, some proteins are also enzymes that contribute to chemical reactions in the body. Among these enzymes professionals particularly interested in one called TOR.

The life of every living organism on the planet, as the life of the planet and our galaxy one way or another ever end

The activity of the enzyme TOR gives the cells the user growth. It is necessary for human organism in the early stages of development and puberty. However, the need TOR further in life and in older age disappears. Today, scientists became aware of the fact that the increased activity of this enzyme is associated with the development of many diseases, including cancer.

Does this mean that the TOR enzyme and other enzymes and genes are the cause of aging? In the course of the study, experts found that TOR accelerates the growth of cells, but at the same time reduces the work of protective mechanisms such as antioxidants. This means that damage to DNA can be viewed as the result of excessive activity of certain enzymes and genes that are responsible for them. However, it is only the result of aging, not its causes. Experts call it the new theory of hyperfunction of aging.

Can we defeat aging?

Despite the fact that numerous scientists in laboratories around the world are trying to unravel the cause of aging, it’s about the fact that in the near future we will be able to turn these processes back is not. In the end, aging is an incredibly complex process. Perhaps it is a payment for the survival of our species. It is also possible that all the matter in the selfish genes — this theory was put forward by the British biologist Richard Dickinson. According to Dawkins all living organisms are “survival machines for genes”. This means that the main goal of all living organisms is the transfer of genes, and not the length of life of a particular living being.

People can be happy at any age

Regardless of which theory of aging do you agree and what not, you should listen to what scientists already know. And it is a lot of data on healthy aging. In the end, proper nutrition, sleep, exercise and care about their health not only today but in the future can make your life better.
