Humans have an obsession with not dying , and have give their corporate brainpower to the scientific task of abolishing death – yet in spite of our greatest efforts , citizenry are not living any longer than they were 20 long time ago , suggest we may have hit the natural ceiling of our lifespan .
appear in the journalNature , a new study has found that while averagelife expectanciesare still uprise across the human race , the maximal old age reached by the planet ’s old people seems to have plateaued in the mid nineties .
To conduct their research , the study authors analyzed datum record in the Human Mortality Database , which contains information on mortality rates in more than 40 countries . Unsurprisingly , they discovered that the proportion of people successfully reach honest-to-god geezerhood without expiring has been increasing steadily since 1900 , which they assign to theever - increase calibre of healthcare .
However , they then looked at data for the US , France , Japan , and the UK , which are the four countries with the highest number of supercentenarians – entail those who live to be more than 110 . In doing so , they obtain that while the maximal age of the sometime people in these countries rose steadily until 1995 , this trend ground then to a hitch , with the age of death of the former person decreasing by 0.28 years per year thereafter .
base on their determination , the investigator calculate the maximum innate human life to be 115 years , although that is not to say that “ unnatural ” ages wo n’t be reached in the future , if science achieves its goal ofdoing away with senescence .
In astatement , study co - author Jan Vijg excuse that “ while it ’s imaginable that therapeutic breakthroughs might extend human seniority beyond the limit we ’ve calculated , such advances would need to overwhelm the many genetic variant that appear to jointly square off the human lifespan . Perhaps resources now being spent to increase life should rather go to lengthening healthspan – the duration of old age spent in good wellness . ”
Though the researchers believe the odds of any mortal living to 125 years old to be less than one in 10,000 , there are still occasional anomaly . The sometime soul on record is a Gallic woman named Jeanne Calment , who died in 1997 at the years of 122 , while a man in Indonesia currently claims to be145 years old – though this still needs to be verified .
