Human aging rate is related to environmental cues

Psychologist Professor Lange pointed out that “the frailty, helplessness, and illness of the elderly is often a learned helplessness rather than an inevitable physiological process.” Many stereotypes of aging cannot withstand scrutiny. . For example, when people get old, will their memory definitely decline? In the face of time, are we really powerless? Is it possible to set a person’s psychological clock back 20 years? Here, psychology will discover this “possibility” for us. The Possibility of Rejuvenation Psychologist Professor Allen Lange, 63 years old, is a professor of psychology at Harvard University, the first woman to receive a professorship in the Department of Psychology at Harvard University, and a member of the Department of Gerontology at Harvard Medical School . He has won many awards such as the Guggenheim Art Foundation Award and the American Psychological Association’s Outstanding Contributions to Public Psychology. In a new Hollywood film “Countdown Clock” that is about to start filming, Jennifer Aniston will play Professor Lange. The main line of the movie is an experiment she did in 1979. In an old monastery in Pittsburgh, Professor Lange and his students carefully built a “space-time capsule”, which was arranged exactly like 20 years ago. They invited 16 elderly people, all in their 70s or 80s, in groups of 8 and let them live here for a week. In this week, these old people were immersed in the environment of 1959. They listened to music from the 1950s, watched movies and sitcoms from the 1950s, read newspapers and magazines from the 1950s, and discussed Castro’s work in Cuba. In military operations, the United States launched an artificial satellite for the first time. They are all asked to live a more active life, such as setting up a table together and tidying up the dishes. No one helped them dress or walk on their feet. The only difference is that the words and deeds of the experimental group must follow the present tense—they must strive to live in 1959, while the control group uses the past tense—to talk and remember what happened in 1959 in a nostalgic way. The result of the experiment is that the physical fitness of the two groups of old people has improved significantly. When they first appeared in Lange’s office, most of them were accompanied by family members, they were very old and faltering. One week later, their eyesight, hearing, and memory have been significantly improved, their blood pressure has dropped, their average weight has increased by 3 pounds, and their gait, physical strength and grip have also been significantly improved. However, in contrast, the experimental group, that is, the elderly “living in 1959” made more amazing progress. Their joints were more flexible, their hands and feet were more agile, and they scored higher in intelligence tests. Several elderly people even played rugby. . Outsiders were asked to look at the photos before and after their experiment, and they could hardly believe their eyes. Over the years, doubts about this experiment have never stopped. After all, this is a field experiment. Because of the lack of laboratory control, a result can have many different interpretations. In fact, until today, Professor Lange still finds it difficult to explain how the brains and bodies of these old people interacted during that week. The only certainty is that these old people psychologically believe that they are 20 years younger, so their bodies cooperate accordingly. In order to maintain a sense of time, those elderly who “live in 1959” must pay more “focus”, that is, “live in the present” more consciously, so their improvement is more obvious. Although it will not “rejuvenate”, this experiment at least proves that the aging in the last stage of our lives is not irreversible. “Aging is an instilled concept.” She went on to say, “The weakness, helplessness, and illness of the elderly are often a learned helplessness, not an inevitable physiological process.” Many stereotypes about aging It cannot stand scrutiny. For example, when people get old, will their memory definitely decline? Evidence from neuroscience shows that more than half of the elderly have the same level of brain activity as young people in their 20s. Their abilities in short-term memory, abstract reasoning, and information processing speed should not be worse than those of young people. So, what is it that inhibits their true potential? According to Professor Lange’s analysis, this is because we are in a society that worships youth and detests old age. When we are young, we take it for granted that we will never grow old. At the same time, we stubbornly and rashly believe that aging is inevitable with weakening. One morning when we woke up, we were horrified to find that we were in old age. This mindset is often extremely lethal. When we find ourselves remember

Will there be scars when opening the eyes? | Pang Lichao Plastic Surgery

Spread the rumors today: Will there be scars when opening the eyes? Not necessarily! Why do some incisions sew up without leaving traces, and some incisions will leave a scar when they are sutured? Because some stitches are performed along the Lange lines, some stitches disturb the lines of the Lange lines, which makes skin healing difficult. Langer ’s Line exists in the skin texture and is the connecting line between the subcutaneous tissues. It was proposed by the Australian anatomist Karl Langer in 1861. The Langer line, or skin tension line, is invisible to the naked eye and is an in-skin feature. It is located at the position of the smallest stretch of the skin, exists in the skin itself, and is widely distributed in the epidermis. Like the mesh, it is correspondingly coupled with the collagen fibers of the dermis layer, which constitutes upward support to the skin tissue. So that the skin will not relax, sag, and deform. Its shape, direction, curvature, and elasticity determine the texture, brightness, and overall skin relaxation of the skin epidermis. We are covered with Lange lines all over the body, and Lange lines are particularly widely used in medicine. Surgical incisions made according to the Langer line can achieve the best effect of skin healing. In addition to surgical operations, there are also very popular “line carving” and “embedding thread” that are also operated according to the Langer line. There are many ways to open the corner of the eye. Common methods include “V-Y & quot. Suture method,” Z “plastic surgery and four-valve method. Different eye types can choose different methods. Some doctors will have their own unique methods, but it doesn’t matter. Either way, scars will be left. (Girl, do n’t be afraid, please listen to me if you have n’t finished talking.) Why do I have a lesser chance of leaving scars when opening my eyes? If it ’s mild, the word “one” is more efficient and better But the word “Z” is better for moderate to severe internal eye angle problems. And after the incision, the internal tissue should be loosened, especially the orbicular muscle in front of the inner canthus ligament, to avoid excessive tension, and the front should also be firm at the same time, otherwise Internal muscle tension will increase scar formation. Good operation and design can minimize scars in the inner corner of the eye. Generally speaking, the scars that appear in the open corner of the eye are mainly scar hyperplasia. In fact, surgery does not leave us scars. Because of scar contracture, it is easy to appear at movable joints, such as the neck, corners of the mouth, inner and outer corners of the eyes, etc. This situation does not occur when the stitches are removed, and generally only about half a month after the stitches are removed. Normal In some cases, the scar will gradually recover after about 90 days, and it will hardly be seen in about 6 months. So, the scar at the corner of the eye is only temporary, and it will slowly disappear afterwards. In addition, the experienced doctor will also hide the scar “Rise up. The incision doctor during the operation usually overlaps part of it with the skin folds, or hides in the concave shadow of the corner of the eye, and the scar will not be visible after the wound recovers. However, this requires a higher level of doctors, not only need to be familiar with the eye Anatomy of the part, and also have rich clinical experience and good aesthetic ability. If the incision is too large, the wound is difficult to heal, and it is easy to form scars, or the incision angle is not good, it can not be well hidden, so be careful of the beauty, choose The doctor is also very important. How to avoid scar hyperplasia? 1. Are you a scar physique? Open eye surgery requires surgery, so scars are inevitable, but the average person can recover, and some people cannot recover because of the scar physique. Suggestions Before surgery, you should know whether you have a scar physique. If it is a scar physique, it is best not to perform the operation. The chance of scarring will be very large. 2. Is the doctor qualified? Will the operation of opening the corner of the eye leave scars? It has a lot to do with it. The operation range for opening the corner of the eye is extremely small, the surgical tools used are also very delicate, and the requirements for the doctor are very strict. The highly skilled doctors can basically see no scars after the operation. 3. Are the postoperative care done? Before removing the thread, avoid getting water on the surgical site, and pay attention to clean the wound and avoid infection. These are the most basic. Improper diet and improper care will stimulate the wound and lead to scar hyperplasia. Finally, remind you to choose a regular hospital for corner surgery The premise is that there must be sufficient psychological preparation. Don’t take too much trouble during the scar recovery. You can apply some scar removal products after the operation to help the wound recover.
