Time fleeting. And with age begins to go even faster. What seemed like an eternity at 8 years old, I think five minutes on the threshold of eighty. Today, the average life expectancy in different countries 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 people will live much longer, like 120 and even 130 years. This is the opinion of the founder of Space X, Elon Musk, and the founder and owner of Alibaba Jack MA and does believe that people will live not less than two hundred years. But what if they are wrong, and we have already reached the limit for their species?
The reasons why people can live longer than 120 years
Let’s start with the fact that one of the key drivers of the increase in life expectancy is infant mortality. In 1800, 43% of newborns around the world died before reaching the age of five. In 1960 the infant mortality rate was 18,5%. And in 2015, according to the world health organization, this figure was 4.3%.
Also, mortality rates have changed greatly since the 19th century. 50-year-old man, who lived in England or Wales in 1850 could expect to live another 20 years. Today, life expectancy for 50-year old man increased by an additional 33 years. Medical advances over the last century and access to health facilities has helped to increase survival rates in different ages.
Regenerative medicine: the way to longevity of mankind. Are we close to that?
Taking into account technological and scientific progress, today, many do not rule out the possibility that life expectancy could increase in the future. So, according to Jack MA in the next three decades, scientists will find a way to significantly extend the life. Also, the Chinese billionaire does not exclude that we will learn the secrets of immortality. The main arguments Jack MA brings modern technology and the transition to three-day working week for 4 hours. Let’s discuss it in our Telegram chat
Elon Musk also believes that 70-80 years is not the limit. The founder of Space X looks to the future with less optimism than Jack MA, however, believes that the development of technology, including artificial intelligence, can significantly extend the average life expectancy of 30-40 years.
Billionaires-enthusiasts are not the only one who predicts the increase of life expectancy. Their views also expressed by some scientists, as according to a study published in 2017 in the journal of Gerontology, convincing evidence that we have reached the lifetime limit no person.
Thus, proper nutrition, adherence to work and rest, good environment and strong friendships and family ties, along with the development of technology and the advent of artificial intelligence, it can have a positive impact on life expectancy in the future.
Why people can’t live more than a hundred years
And yet there is an opposite point of view, proponents of which believe that members of our species are unlikely to live more than a hundred years. All because of aging, because it is directly linked with health. In the end, don’t people living longer because they are healthier? Aging also brings with it new health problems, which are too familiar to all who cares for older relatives or yourself is getting older.
If people live longer, health in the long term will require special attention to healthy habits, beginning in childhood. According to scientists from Stanford University, who study problems associated with aging, we need to focus on extending healthy life, not increase its length as such.
In addition, the assumption that the life expectancy of a particular person also increases with increasing life expectancy, introduces the public astray. So, according to some scientists, a safe environment and better living conditions today are more significant factors contributing to the increase in the duration of human life than even the achievements of modern medicine.
And it is not excluded that we have reached the lifetime limit. So, according to the office for national statistics, UK life expectancy in the years 2015-2017 have stopped increasing for the first time since 1982.
A recent study published in the Proceedings of the National Academy of Sciences biologist from Stanford University śrīpāda Tuljapurkar showed that the average life expectancy among those who crossed the mark of 65 years, increasing by three years every 25 years. This means that people can live on average six years longer than their grandparents. That’s great, but we are talking about six years rather than 26 and more.
What forecasts to believe
As tempting as sounded speech about the life length of 120 or 200 years, to me personally, this prospect seems rather doubtful. In order to lead a healthy and full life needs fresh air, quality food and access to modern medicine. Not to mention the 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, regardless of what the future holds for our species, every one of us today can make your life more comfortable and healthy. And this, in turn, will increase life expectancy. Healthy and varied nutrition, sleep and regular exercise are the most reliable and trusted on ways to make your life more enjoyable and long.
