I believe that many people know that by looking at the growth rings of a tree, you can know the approximate lifespan of the tree, which is a way for nature to give organisms a minimum way to judge the lifespan, and experts believe that through the special structure of some organisms, the lifespan of different species can also be judged. In a previous scientific study, there was a new discovery, which can actually judge the life span of a person through his eyes.
Eyes are one of the most important human senses, they not only allow us to see the world around us, but also reflect on our health. A recent study found that the eyes are indeed able to reveal a person's lifespan.
Experts believe that the approximate lifespan of a person can be seen by the age of the person's retina. The retina is the outermost layer of tissue in the eyeball, which contains the optic nerves and blood vessels. Studies have shown that a person's retina changes with age, similar to the changes in age in other parts of the body. The results came after 11 years of research with nearly 50,000 participants. Therefore, by observing a person's retinal age, it is possible to make a preliminary judgment about their health and lifespan.
The retinal age gap is also an important indicator. Some people have a much younger retinal age than they are, which is usually a sign that they are otherwise healthy as well. Conversely, some people have a much older retina age than they are, which can mean that they have problems with other aspects of their body and their longevity may also be affected.
Observing life expectancy is an interesting task. While we can't know exactly how long a person lives, we can get some clues by looking at their retinal age. This new discovery provides a new direction for scientists and an easy way to understand our own health and longevity.
If you want to see the difference between a person's actual age and retinal age, you need to use high-tech means to be able to judge, and this may be a new direction of scientific development in the future, which can also let more people know their future life expectancy. Of course, this study has not been supported by many people, and it is still in the process of research.
