Reading guide: Age may really be just a number, or that for different people, the concept of time is different, at least in physical performance------ child doctor
What is the concept of time, and is age really related to time?
We all keep track of our age, thinking how old we should be to do what we should do at that age, as if this is a consensus, and even considered the truth.
From young to old
But is it true that our physical age is increasing as we age?
In daily life, we have seen too many people who are not old and decrepit, and we have also seen many "myths of immortality", and even some people are obviously the same age, but they are completely like two generations.
In this regard, Dr. Tong believes that age may be just a false proposition.

Perhaps, some people will say that even if different people are of the same age, it is normal for the influence of lifestyle habits and other factors to change the degree of aging of the face.
This seems to make a lot of sense, but what would Dr. Tong think about it if Dr. Tong told you that even if a person is not aging in sync with the various organs in his body?
Recently, scientists from Stanford University in the United States published a relevant paper in the journal "Nature", showing that the aging is not the same between individuals, and the aging rate between different organs of the same biological individual is not exactly the same.

Regarding the research results of British scientists, Dr. Tong instantly had a sense of enlightenment about some medical doubts.
Generally speaking, the aging of various organs of the same human body should be relatively synchronized, but many people suffer from diseases at a relatively young age that should not be at this age.
This is a typical manifestation of inconsistent aging of individual organs, and many diseases are getting younger and younger, does this mean that these individuals have congenital defects in their diseased organs?
If this is really the case, then whether we can judge the "true" age of a certain body organ in advance by means of a certain week, and then intervene or treat this organ that ages significantly faster than other organs, so as to avoid the emergence and development of diseases, will become a new treatment idea for future medicine.
medicine
Importantly, this solution is feasible, and scientists in the United States can infer the true biological age of a person and an organ by analyzing the protein expression of a volunteer's proteome sample, and analyzing the effect of the protein on the biological age of different organs with the help of machine learning models.
Once we know the true biological age of a certain organ, we can calculate how much risk the person will have in the future to suffer from diseases of that organ, for example, when a person's heart ages too fast, the risk of heart failure will increase by 2.5 times, the risk of cognitive decline will increase significantly in individuals with rapid brain aging, which means that they are likely to suffer from Alzheimer's disease in the future, and the kidney will age too quickly will cause diabetes and high blood pressure.
Medical monitoring
At the same time, the researchers also found that more than 20% of the volunteers had at least one organ in a state of Progeria, while the proportion of more than two organs in a state of Progeria was 1.7%, and the researchers also said that individuals with two or more organs with Progeria had a 6.5 times higher risk of death than normal individuals.
Perhaps in the future, we can use the detection of premature aging of human organs as an important means to reduce the occurrence of certain diseases, which is of great significance for human health promotion.
Young is full of energy
In addition, Professor Wyss-Coray of the research project said, "Even premature aging is not incurable, and perhaps some organs can be rejuvenated by blood replacement," adding that he had done experiments in 2014 to make the brains of older individuals younger by transfusing blood from young mice.
Although birth, old age, sickness and death are natural laws, but the premature aging is something that everyone does not want to meet, and our medical development still has a long way to go, but every discovery is a ladder on the road of human medical progress.
