Have you ever seen a 191-year-old tortoise? It's no joke, it's a true story.
The turtle's name is Jonathan, and it is an African tortoise that was born in 1829 and currently lives on the island of St. Helena in the South Atlantic. It is the longest-lived terrestrial animal in the world and one of the oldest animals alive today.
It has seen two world wars, four British queens, and more than a dozen American presidents. It is even older than the oldest building on the island of St. Helena.
Jonathan's birthday is March 14 every year, and this year it celebrates its 191st birthday. So, why did Jonathan live so long? Is there any special secret to it? Let's find out.
1. The mystery of the tortoise's lifespan
Turtles have a very long lifespan, generally living to be 50-100 years old, and some can even live to be more than 200 years old. The lifespan of turtles has a lot to do with their physiological characteristics and Xi habits.
Turtles have a low metabolism, which means that their bodies use very little energy, which reduces oxidative damage to cells and the production of free radicals.
Free radicals are unstable molecules that can damage the structure and function of cells, leading to aging and disease. The low metabolism of turtles also allows them to survive for a long time without food and water, as they can use their own fat and water to stay alive.
Turtles are also genetically special in that they have a structure called telomeres that are located at both ends of the chromosomes and protect the integrity of the chromosomes. Each time a cell divides, the telomeres shorten a little, and when the telomeres disappear, the cell stops dividing and enters the process of aging and death.
Turtles have long telomeres, and there is an enzyme called telomerase that repairs damage to telomeres, thereby extending the life of the cells.
Turtles have a strong immune system, and they can fight off various pathogens and keep their bodies healthy.
There is a substance called antithrombin in the blood of a turtle that prevents blood clotting and prevents the formation of blood clots. Blood clots are dangerous blockages in blood vessels that can lead to fatal diseases such as heart disease and stroke. The turtle's blood also has a substance called antimicrobial peptides, which can kill a variety of pathogens such as bacteria, viruses, fungi and parasites, enhancing the body's ability to fight disease.
The lifestyle of turtles is also good for slowing down aging, they are rarely disturbed and stressed by the outside world, and can enjoy the beauty of nature quietly. They don't need to fight for food and territory, they don't need to compete for reproduction, and their sex can also change according to the temperature of the environment, which avoids the spread of some genetic defects and diseases.
They can also hibernate or hibernate according to seasonal and climate changes, which can save energy, reduce losses and prolong life.
2. The enlightenment of the life span of the turtle to mankind
The mystery of the tortoise's lifespan has always fascinated human curiosity, and humans have been looking for ways to extend their own lifespan. By studying the physiological characteristics and living Xi habits of turtles, humans can get some inspiration and reference from them.
Humans can reduce the production of free radicals and protect the health of cells by regulating their metabolism.
This can be achieved through a sensible diet, moderate exercise, adequate sleep, and reduced stress. Humans can also supplement some antioxidants, such as vitamins C, E, and β-carotene, to neutralize the harm of free radicals and delay the aging process.
Humans can extend the lifespan of their cells by improving their genes. This can be achieved through technologies such as gene editing, gene therapy, or stem cell transplantation. Humans can modify their telomere and telomerase genes to increase the number of cell divisions and prevent cell aging and death.
Humans can also repair their own genetic defects to prevent and treat some hereditary diseases, such as cancer, Alzheimer's disease, and Parkinson's disease.
Human beings can maintain their health by strengthening their immune system to resist various pathogens. This can be done by getting vaccinated, taking antibiotics, etc.
Human beings can delay their aging and improve their quality of life by improving their lifestyle. This can be achieved by maintaining a positive mindset, cultivating a good Xi, and enjoying a harmonious environment.
Humans can reduce their worries and stress and increase their sense of happiness and satisfaction by Xi learning some of the turtle's wisdom, such as conserving resources, avoiding conflict, and adapting to change.
summary
Turtles are very amazing creatures, and the mystery of their lifespan has always inspired human exploration and innovation. By studying the physiological characteristics and living Xi habits of turtles, humans can get some inspiration and reference from them to prolong their own lifespan and enjoy a long and happy life like turtles.
