HUMANS will continue to get older and older… and older. There is no limit to how long people will live and there will be more “super centenarians” living to over 120, scientists have claimed.
Experts last year claimed humans would “only” reach the ripe old age of 115 years – with a few managing to wait until they were 125 to pop their clogs.
Research Fellow Dr Xiao Dong and colleagues at the Albert Einstein College of Medicine in New York suggested human lifespan had peaked and a biological “barrier” reached.
But a new study by McGill University biologists argue that there is no evidence that maximum lifespan has stopped increasing and that the original study was flawed.
In fact, they believe super-centenarians will become more common as average life expectancy rises.
By analysing the lifespan of the longest-living individuals from the USA, the UK, France and Japan for each year since 1968, the McGill researchers found no evidence for such a limit, and if such a maximum exists, it has yet to be reached or identified…
I like the idea that so far, modern medical science has a 100% failure rate. It has not saved a single person from death. If nothing else, old age gets you, eventually. This may not be inevitable, however. There are real biologically immortal animals.
Biological immortality is a state in which the rate of mortality from senescence is stable or decreasing, thus decoupling it from chronological age. Various unicellular and multicellular species, including some vertebrates, achieve this state either throughout their existence or after living long enough. A biologically immortal living being can still die from means other than senescence, such as through injury or disease. …
Turritopsis dohrnii, or Turritopsis nutricula, is a small (5 millimeters (0.20 in)) species of jellyfish that uses transdifferentiation to replenish cells after sexual reproduction. This cycle can repeat indefinitely, potentially rendering it biologically immortal. This organism originated in the Caribbean sea, but has now spread around the world. Similar cases include hydrozoan Laodicea undulata and scyphozoan Aurelia sp.1.
Why not us? Scientists are working on it as you read this. It is possible that the first person to live to 200 in recorded history has already been born.
What would you do tomorrow if you learned today that you are biologically immortal?
