Some older people have strong immune systems, although their metabolism slows down due to physical problems. Some older people, because their immune systems are weaker, have the same metabolic rate as younger people and consume alcohol more quickly during drinking.
Aging begins gradually after 25 to 30 years of age, but the internal or internal performance of different parts of the body is different. Molecular theories related to aging, such as shortening of telomeres and expression of related proteins, take a holistic view of this problem.
There are different types of aging
In the nature Medicine study, Stanford University School of Medicine, us, said people have different aging and genotypes, and researchers said predicting these changes in advance of old age could have a positive impact on longevity.
Norrina Bai Allen, of northwestern University’s Feinberg School of Medicine, said the discovery of differences in the rate of ageing in different parts of the body could shed light on scientists’ understanding of ageing. Researchers at Stanford University said the differences in the rate of ageing among individuals were linked to differences in biological mechanisms known as “types of ageing”. Although people as a whole are aging, some physiological systems in an individual’s body age faster or more slowly than others, even at the molecular level, and are bound to be different as they gradually “wither away.”
Second, the life span also can the human intervention
In this study, the researchers also found that the physiological system aging faster is not the same as the corresponding symptoms. If the idea that there are differences in aging among individuals is true, then the corresponding intervention can be implemented based on the analysis of the type of aging of the individual. The researchers say it is possible to know which parts of the body are aging faster and pay more attention to these changes, based on what type of aging you are.
For example, people with aging cardiopulmonary systems need to pay more attention to cholesterol, electroencephalogram and atrial fibrillation, while people with aging immune systems need to pay more attention to exercise and diet, the researchers said. But the researchers said the study’s time with participants was limited, so many factors, including the role of markers of aging in the body, are uncertain, and further research is needed to build on the theory.
Even so, the researchers have identified four common types of aging — immune, liver, kidney and metabolic — as well as the as yet unidentified heart and nerve types, and the new study sheds new light on the differences between aging and longevity, and why those differences exist.
Have a younger biological age
Average measurements of some biomarkers in the experiment increased with age, while others fell with age, such as heme A1C, a marker that measures how cells metabolize glucose and is also a biomarker of metabolic senescence. But in many people there is a downward trend, suggesting that different systems in different people age at different rates.
Many counter-examples may arise because individuals are making the transition to a healthy lifestyle. People with a significant drop in hemoglobin A1C, for example, either ate healthier diets or exercised more, because both changes boosted glucose metabolism. Lifestyle changes, or supplements, could improve some biomarkers of aging and lead to age-related changes in individuals, the researchers said.
David Sinclair is best known in academia for his discovery of the role of -nicotinamide, a direct precursor to coenzyme I and a central component in the mechanism of action of Letterviken -nicotinamide. According to Global Science, Harvard geneticist Professor David Sinclair made the surprising claim that scientific data showed he was more than 20 years younger than his actual age. A 49-year-old with many of the same physical indicators as a 20-something, what’s the secret?
He said in an online post that he takes a molecule called beta-nicotinamide (the main ingredient in Lightwiggen NMN) every day. He has a resting heart rate of 57, like an athlete. He had the lung capacity and blood pressure of a 20-something.
In fact as early as in 2013, David Sinclair, the team found that coenzyme in mice after supplement the material I level rise, mice aging speed reduced to two thirds of the natural state, its steady state key indicators such as mitochondria mice back to 6 months of age similar state, and then the material is Wright d health market cause.
Adopting healthy living habits can not only prolong life, but also make people live healthier lives. But understanding aging patterns may help people take anti-aging measures in response to major aging pathways. “Once you have identified the main causes of aging, then you can do something about it,” Campisi said. “A person in their 40s or 50s can tell their biological age from a blood test and then you can do something about it This study gives us a solid step in that direction.”
