Do people age slowly? In fact, aging always comes suddenly, such as at the age of 34.

We always think that people grow old little by little, but in fact it is different from what we think, because aging always comes suddenly and silently.

When we are young, we always feel that aging is far away from us. When we look in the mirror, we can't even believe how our youthful face will gradually wither. But when aging really comes, it always catches us off guard. At a certain moment, we suddenly feel that we seem to become ugly. This is when aging comes to us. For many people, this moment happens around the age of 34. Why does aging suddenly come from the sky? This starts with the nature of aging.

The human body is made up of cells, from the skin on the outside to the internal organs, without exception, and protein composed of amino acids is an indispensable and important component of all cells.

Human aging is essentially the aging of cells, and the aging of cells begins with changes in proteins. A research team led by Tony Corey, a neuroscientist at Stanford University, found that when people reach the age of 34, the composition of proteins in the human blood begins to change significantly, and the levels of some proteins drop significantly. These disappearing proteins are closely related to appearance.

Because levels of these appearance-related proteins drop dramatically, collagen is lost rapidly and changes quickly become apparent in the skin.

At a certain point around the age of 34, our skin will lose its elasticity and luster, gradually become loose, and even accelerate the formation of wrinkles, and even the muscles will collapse. All this happens so quickly that we don’t even notice the process of this change. Only one day, when we have time to look at ourselves carefully, we will suddenly find that we seem to have become ugly, but for a while we can’t find the reason for the ugliness. In fact, even if we find the reason, what can we do? The only thing we can do is accept it.

The essence of aging has nothing to do with any external factors. It is actually aging at the protein molecular level.

In a person's life, there is not just one time point when they suddenly age, but three, and these three important time points are called the three major watersheds of life. The first is 34 years old. At this time, aging is mainly manifested in appearance, which can be regarded as a reminder from the messenger of time. The second time point is 60 years old. Aging during this period is no longer limited to the level of appearance. Our bodies will be fully affected. At this time, we will become a real old man, our movements will gradually become slow, and our physical strength will also show a significant decline. For most people, strenuous exercise will completely bid us farewell.

If we live long enough, we will reach the last important aging node in our lives, which is 78 years old.

Research has found that at the age of 78, the amount of disease-related proteins in the human body will increase significantly. This aging process will make us lose our health and enter the final stage of life. At this point, we can begin to lament the brevity of life. Why do people have to age? Because DNA cannot be perfectly replicated, errors will occur every time it is replicated. In order to correct this error, telomeres exist at both ends of chromosomes, but every time they are replicated, the telomeres will shorten until they disappear.

Although aging cannot be stopped, it can be delayed.

Studies have found that the shortening rate of chromosome telomeres is closely related to people's living habits. Appropriate exercise can effectively extend the length of telomeres. The good news is that you don't need much exercise, as long as you walk faster, it will work. After studying the genetic data of 400,000 adults, the relevant research team found that compared with people who walk slowly, people who walk at a moderate speed and fast speed have significantly longer telomeres at the same age. Based on this, brisk walking may be a good way to delay aging. Of course, a healthy diet and maintaining an optimistic attitude are equally important.
