We dream of a time when modern medicine would allow humans to live beyond the age we know today, but is there an upper limit of what is biologically possible?
Yes, according to a new study. This suggests that the maximum human lifespan is probably around 150 years.
This research delves into biological aging, or aging – how quickly our bodies deteriorate. which may or may not correspond to our chronological age (How many days do we celebrate birthdays?)
In this case, scientists developed a new way to interpret fluctuations in the number of different types of blood cells. This results in a measurement known as the Dynamic Life Status Indicator (DOSI).
over time body will gradually slowly recover Which is one of the reasons why we recover from disease and injury longer.
The researchers said Assuming we can avoid disease, disaster, and ninja-killers throughout our lives, DOSI is a reliable way to show when that resilience runs out.
“Explaining this trend suggests that the DOSI recovery time and variance differ at the 120-150 year critical point corresponding to a complete loss of resilience,” the researchers explain in their paper.
Blood cell count data from more than half a million people, taken from research databases in the UK, US and Russia, were analyzed along with the step count data of 4,532 people to measure the rate of decline in physical performance of the blood cell count. people
Blood cell counts may point to a number of problems in the body, ensuring it is a good general indicator of overall health and recovery. The team then used the step count data to double-check their thinking.
Another finding from the data is a change in aging trajectories from age 35 and over and again from 65 and over, consistent with existing boundaries in society, such as the age at which people tend to retire from elite sports. and the age at which people tend to retire from full-time work.
Moreover Researchers say the study could be used to inform treatments that can target disease and illness without affecting biologic resistance. And perhaps one day extending the maximum possible life expectancy is greater than it already is. We need more research and a lot of data first.
The new analysis is generally consistent with previous studies that referred to a maximum life expectancy of about 120-140 years, although when calculating this number, the average life expectancy is about 120-140 years. There are some educated guesses and estimations.
while writing The oldest ever age was 122 years 164 days, by French woman Jeanne Calment. What this study points out is that without drastic changes in our bodies at the baseline level. It would be difficult to squeeze our fragile form for years to come.
“We conclude that the crises that result in the end of life are intrinsic biological properties of organisms independent of stress factors and indicate fundamental or absolute human life expectancy,” the researchers write.
