Re: Does the human lifespan have a limit?

Whenever this topic comes up, I’m always reminded of the fact that the bible knew of this long before any statistician. 'My spirit shall not abide in man for ever, for he is flesh; his days shall be a hundred and twenty years' (Gen. 6:3). As a non Christian this always baffles me.

How many numbers are in the Bible, and how many of them are wrong (which we conveniently gloss over). The world was made in 6 days?

So if we get a single human who, without dispute as the oldest woman has some controversy as to the validity of her age, lives past the age of 120 will that be proof the bible is untrue and all it’s writings are false? Because I have a funny feeling now that people are much more documented we will pass the 120 year mark any time.

Not really. Because it wasn't a hard limit. Even after the Bible records that God said this, it records people living to 450, 175, 120 years and so on. After God said, the span gradually reduced to well below 120. So, a case could be made that it wasn't a hard limit.

No, it will prove that Biblical literalism is false, but that's a novel minority doctrine in Christianity that is already disproven by (among other things) the two conflicting creation sequences in Genesis.

Well, the chapter prior to that one describes humans living for hundreds of years, so I don't think someone living past 120 will really introduce any more theological problems.

My recommendation to you would be to not read ancient sources. Secular sources are not any more rigorous.

If we consider the average lifespan as say 80 years old, I find it quite interesting that no single human ever has achieved even close to twice that age.

Why?

I think the GP just means that the tail of the age bell curve seems (surprisingly) short to them.

The implication being that when doing statistics with a large number of data points, you often see several outliers that are way outside the curve. In the case of age, the tail of the curve falls to 0 very quickly.

Doesn't DNA have a halflife of like 512 years? I imagine if every cell in the body affected by that there isn't a way to prevent it all from destabilizing by that point.

Presumably that doesn't apply if your cells are continuously reproducing creating new copies of DNA. In some sense your DNA comes from your parents and extending back through those lineages has lasted vastly longer than 512 years.

That’s an incredible verse: we underestimate the wisdom of the ancients sometimes.

On the contrary, it's incredibly common for people to want to believe that the ancients were somehow better or wiser than we are, or marvel over supposedly impossible feats (see: pyramids, Greek fire, occasionally semi-correct guesses about the nature of the universe).

They were just people like us; right sometimes, wrong much more often, but in their case, lacking the tools to verify most ideas.
