This question already has an answer here:
Excluding situations where you die from accidents, the main reason for death is -generaly- diseases.
And usually it is about an organ which becomes "tired" after many years. These results are all from experience and statistics:
But I've never heard of any study that said: "people can't live longer than x age because the heart can't live longer than that".
From my point of view, I think it's us who control the way we live and consequently someone can live longer than the other. For example, smokers die at an early age.
But even the oldest person in the world, lived for 122 years and 164 days. For me this isn't enough. It seems that someone can't control his age after all.
Basically my question is: Does science provide any limit that a person isn't able to live more than it? For instance can someone live more than 1000 years?
Note: I don't think someone is able to do this because simply even our healthiest habits are not "so" healthy. But imagine someone who doesn't live like any of us as humans, i.e. Can have a very healthy and natural life
