Time is fleeting. And with age begins to go even faster. What seemed like an eternity at 8 years old seems like five minutes on the threshold of eighty. Today, life expectancy in different countries of the world varies from 83 years in Japan to 48 years in Burundi (Africa). In Russia, the average life expectancy, according to various estimates, ranges from 72 to 75 years. We all want to think that in the future, a person will live much longer, for example, 120, or even 130 years. This opinion is shared by the founder of Space X, Elon Musk, and the founder and owner of Alibaba, Jack Ma, believes that people will live for at least two hundred years. But what if they are mistaken, and we have already reached the limit for our species?
Reasons People Can Live Over 120 Years
To begin with, one of the key factorsAn increase in life expectancy is a decrease in infant mortality. In 1800, 43% of newborns in the world died before they reached the age of five. In 1960, the infant mortality rate was already 18.5%. And in 2015, according to the World Health Organization, this figure was 4.3%.
Also, mortality rates have changed a lot since19th century. A 50-year-old man who lived in England or Wales in 1850 could expect to live another 20 years. Today, life expectancy for a 50-year-old has increased by an additional 33 years. Advances in medicine over the past centuries and access to medical facilities have helped increase survival rates at various ages.
Regenerative medicine: the path to human longevity. Are we close to this?
Given the technological and scientific progress,Today, many do not exclude that life expectancy will increase in the future. So, according to Jack Ma, over the next three decades, scientists will find a way to significantly extend their lifespan. Also, the Chinese billionaire does not exclude that we will learn the secrets of immortality. Jack Ma cites modern technology and the transition to a three-day work week of 4 hours as the main arguments. Let's discuss it in our Telegram chat
Elon Musk also believes that 70-80 years is notlimit. The founder of Space X looks to the future with less optimism than Jack Ma, however, believes that the development of technologies, including artificial intelligence, can significantly extend the average life expectancy in 30-40 years.
Enthusiastic billionaires are not the only onespredicts an increase in life expectancy. Some scientists also adhere to their opinions, since according to a study published in 2017 in the journal Gerontology, there is no convincing evidence that we have reached the limit of human lifespan.
Thus, proper nutrition, compliancethe regime of work and rest, a good environment and strong friendly and family ties, along with the development of technology and the advent of artificial intelligence, may well have a positive effect on life expectancy in the future.
Why people can not live more than a hundred years
And yet there is an opposite pointview, whose supporters believe that representatives of our species are unlikely to live more than a hundred years. The whole blame for aging, because it is directly related to health. After all, don't people live longer just because they are healthier? Aging brings with it new health problems that are too familiar to anyone who cares for elderly relatives or is getting older.
If people live longer, maintaining health inThe long term will require special attention to healthy habits, starting from childhood. According to scientists at Stanford University, studying the problems associated with aging, we need to focus on prolonging a healthy life, rather than increasing its duration as such.
In addition, the assumption thatthe life expectancy of a particular person also increases along with an increase in average life expectancy, which misleads the public. So, according to some scientists, a safe environment and better living conditions today are more significant factors contributing to an increase in human life expectancy than even the achievements of modern medicine.
And it is still possible that you and I have reachedlife span limit. So, according to the UK Office of National Statistics, life expectancy in 2015-2017 has ceased to increase for the first time since 1982.
A recent study published inProceedings of the National Academy of Sciences by Stanford biologist Sripad Tuljapurkar, showed that the average life expectancy among those who have crossed the mark of 65 years, increases by three years every 25 years. This means that people can live on average six years longer than their grandfather and grandmother. It's great, but it's about six years, not 26 or more.
What predictions to believe
No matter how tempting the talk of life in length120 or 200 years old, I personally see this prospect as rather dubious. In order to lead a healthy and fulfilling life you need clean air, quality food and access to modern medicine. Not to mention access to modern technology. And let's not forget about the problems associated with climate change, because they are directly related to life expectancy.
However, no matter what the futurewaiting for representatives of our species, each of us today can make our lives more comfortable and healthy. And this, in turn, will contribute to an increase in life expectancy. A healthy and varied diet, sleep, and regular exercise are the most reliable and proven ways to make your life more enjoyable and long.
