Humans probably can't live longer than 150 years, new research finds:
Science is once again casting doubt on the idea that we could live to be nearly as old as the biblical Methuselah or Mel Brooks' famous 2,000-year-old man.
New research from Singapore-base biotech company Gero looks at how well the human body bounces back from disease, accidents or just about anything else that puts stress on its systems. This basic resilience declines as people age, with an 80-year-old requiring three times as long to recover from stresses as a 40-year-old on average.
[...] Extrapolate this decline further, and human body resilience is completely gone at some age between 120 and 150, according to new analysis performed by the researchers. In other words, at some point your body loses all ability to recover from pretty much any potential stressor. The study's conclusion that the body loses all ability to cope -- or at least to recover -- from stress before age 150 is line with the conclusions of similar studies, including one from last year that pegged the maximum possible human age at 138 years.
The full study [PDF] is published and available to the public in the open journal Nature Communications.
I think that quality of life is much more important than number of years. Would you like to live longer?

the "you" or "me" starts (or stops) with the skin boundary.
but we kinda know (thank you yoghurt industry) that "me" or "you" is also alot of stuf that didn't come out of the original mom but was acquired (or invaded).
so methinks, this other stuff, after a few years "on the outside" is like a second "me" or "you".
the body adapts (or is shanghaied) to this.
how this adaption influences ageing:
either the " other me" evolves and/or our immune system has limited capabilities (like a library has limited space for books).
maybe if we could keep an environment with other "me" or "you" consistant over a long time, the original "me" or "you" would live longer. ofc the "original intruders" themselfs have to evolve and adapt constantly. if the pressure can be reduced, it will also (not) propagate to the original "me" or "you".
in short, we cannot survive without bugs. if we can keep " our bugs" healthy, like keeping breathing air and drinking water clean, we can live longer too?
