Every time I look in the mirror, there are people who sigh that it seems to be getting older differently. But does a person really grow old little by little?

The bottom line is that you don't grow old at a constant rate, but you're old. Research shows that aging in humans occurs only three times in a lifetime.

According to a paper by Stanford University researchers published in the journal Nature Medicine, aging progresses rapidly at 34, 60, and 78 years of age.

Stanford researchers isolated plasma from 4,000 blood of various ages and analyzed proteins in the plasma.

As a result, we found that some of the protein levels increase with age, and the most noticeable period of rapid change is 34, 60, and 78 years of age. .

In addition, most of the protein in the blood is taken from other organ tissues, but if the protein is from the liver, it means that the liver is aging.

Unfortunately, the causal relationship has not yet been determined whether the protein levels change because humans are old.

But if the research goes on, a drop of blood can measure an individual's level of aging in the body, and the protein may be able to rejuvenate an aging organ.

In any case, I don't need to be too hasty to get one year old and one year old every year.
