　　Now, scientists believe that they can slow down people's aging rate and make them a healthy life span of more than 110 years, or even 120 years.

　　sounds like science fiction, but researchers have shown that metformin, which is used to treat diabetes, can extend the life of animals. The US Food and Drug Administration has now approved a clinical trial to see if the drug has the same effect in humans. From a biological point of view, if

　　The experiment is successful, so people in their 70s will be as healthy as people in their 50s. This may usher in a new era of geriatrics. By then, doctors no longer need to treat cancer, diabetes, and dementia separately, but only need to treat the basic mechanisms of aging.

　　Professor Gordon Lisgow, a Scottish anti-aging expert, works at the Back Aging Institute in California, USA, and is one of the consultants for the above research. "Taking the aging process as a research topic and delaying aging will also delay all aging-related diseases. This is innovative and unprecedented." Empty. Every cell contains a blueprint for DNA, so the human body can always function normally. Some marine organisms do not age at all.

　　But in our lives, we need to undergo billions of cell divisions to maintain normal body movement. The more units are divided, the more errors will be involved in this process. As cell problems increase, the body will eventually be unable to repair the damage. In the case of cancer, the cells can no longer remove the mutation and the tumor continues to develop. Take Alzheimer's disease as an example. When the brain stops removing amyloid plaques, symptoms of dementia will appear.

　　Scientists believe that the best anti-aging drug is metformin. It is the most widely used hypoglycemic drug in the world, and it can be taken for only 10 pence (about 15 cents) a day. Metformin can increase the number of oxygen molecules released into cells, which seems to increase body strength and prolong life.

　　When Belgian researchers tested the nematode metformin, these worms not only age more slowly, but also stay healthy for longer. They did not slow down, nor did they smooth out wrinkles. After using metformin in mice, lifespan was extended by nearly 40% and bones became stronger. Last year, the University of Cardiff in the United Kingdom found that after taking metformin, diabetic patients actually live longer than non-diabetic patients, but theoretically, the average life expectancy for diabetes should be eight years longer.

　　In the United States, a clinical trial called "Metformin Anti-aging" is scheduled to start next winter. Currently, scientists from multiple institutions are raising funds to recruit 3,000 elderly people between 70 and 80 years old. They want to prove that metformin can delay aging and prevent the onset and onset of diseases.
