Scientists calculate the limit of human life span
Every creature living in nature has a certain life span because everything in nature cannot be immortal, this is the law of nature, man can not change, however, the life span of various creatures, including humans, is determined by a variety of factors, such as genetic survival environment and a series of factors.
In ancient times or decades ago those poor years, people's life expectancy is relatively short, however, nowadays human society has long undergone radical changes, and coupled with the continuous improvement of medical standards, people's life expectancy has also been extended.
But since ancient times, both at home and abroad, there are many people have sought the method of immortality, such as many ancient emperors have been exploring the secret of immortality in their lives, but ultimately ended in failure, and then the ancient Egyptian pharaohs will be mummified after death, hoping to resurrect someday in the future.
This issue has to cause us to think deeply, humans can do immortality? In fact, for this matter, once scientists have also given authoritative research and calculations, in the end how the results, here we take a look.

Even so far, people's life expectancy has a certain limit, but I believe we should have heard of those "centenarians" and "longevity village" cases in our daily lives. Although these centenarians have not reached immortality, why their life expectancy can be a further breakthrough? Is it that the human body is still to be developed?
Biologists speculate that the limit of human life expectancy usually does not exceed 140 years, for a normal person, if the body has not suffered major trauma in life immune system is very strong, and life expectancy beyond 100 is not a problem.
However, due to the poor living in the past, nutrition can not keep up, although our living conditions have changed a lot, more and more people have formed bad life and behavior habits, these factors may also affect human life expectancy.
Along with the increase in the average age of the world, the division of the human body's life expectancy also has a new definition, according to the age to divide, within 44 years old for young people, 45 to 59 years old for middle-aged people, 60 to 74 years old for the young elderly, 75 to 89 years old for the elderly, more than 90 years old is a long life.
It can be seen that the middle age of the human body is backward, the average life expectancy of human beings in recent years can already be determined to be about 80 years old, for whether the human life expectancy will be broken, or whether this can be achieved, according to years of experiments and calculations, biologists to all aspects of the impact of factors as a basis for investigation eventually came up with a larger category of signs, that is, 110 years old to 170 years old in the middle.
They speculate that in the future the average life expectancy of people may be maintained at 130 years old or less, although for this value many people feel disappointed, this is only the scientists' speculation, because the future life we can not predict, but also may experience some major changes that affect the human life expectancy, or even let the human life expectancy to achieve a breakthrough.
We don't know what may happen in the future, but this can fill us with infinite yearning and reverie, do you have anything else to say about this? Welcome to send you comments again.

Revolutionary Climate Action
In the retrospect of my childhood, the memories of the visits to the farm with my parents are a mixture of useful advice and interesting traditions. From my grandpa's idea of planting sweet potatoes underneath rocks to my grandmother's statement that we should plant fruit according to the moon cycles, to my dad's funny invention to control the wind during the rice or cocoa sifting, all these practices were both the usual and the interesting to me. Gradually, I began to think about these habits, it made me to think where they came from and how useful they are. My family usually avoided the cultural traditions which they considered as those which they called the eccentricity of my grandparents. However, my professional career was the climate crisis, where I now, as a consultant, help farmers to set up the resilient agroforests. The road that I have traveled has pushed me to start the Cacua Project, a project that is centered on the creation of the agroforests that are resilient and the collaboration between the farmers to the ecosystems management. Hence, I have combined the old knowledge with the modern research, which has a concrete aspect that deals with the climate change. I have gradually come to the conclusion that the old stories and practices handed down from generation to generation are the most beneficial. The partnering with the farmers, we conducted the experiments that verified some of the traditional methods. In addition, the rocks placed under the crops facilitated the drainage and at the same time it drew the good organisms. The method of planting by moon cycles turned out to be successful in the organization of irrigation and pollination by being in sync with the natural insect activity and the water cycles. Even the wind-whistling technique appeared to influence the air, therefore it was beneficial in the agricultural work. The jewels of wisdom which were taught by the ancestors to us are the ones that gave us the necessary tips for the better way of landscape protection. Ever since I was a young environmentalist, I have been committed to several life choices that elude what I consider good for the planet.

Why Just Write Is The Best Advice You Don’t Listen To
Before the last 6 months, I hadn’t written anything that wasn’t for my job or university for a number of years. I wanted to write more, I used to write all the time just for fun. I used to write poems and short stories that were just for me. I used to show them to certain members of my family but it was the process of writing them that I really enjoyed.
