Ancient & Modern Life expectancy

If you look at the lifespan of ancient Greek philosophers, playwrights, poets and politicians, they seem to live till around age 80, like we do.
Of course the aforementioned professions were mostly made up of members of the upper classes, who had a higher standard of living than their poor.
However, the average ancient Greek male married at 30.
If they were marrying so late, they must've been dying late too.
I don't think modern medicine and such has improved our life expectancy and health nearly as much as we suppose, perhaps conditions now are better than they were in the middle ages, but it doesn't appear they were that much better, if at all than ancient Greece and Rome, despite the modern, mainstream medical world harping on and on about the benefits of their antibiotics, drugs, vaccines and so on.
And some controversial scientists like Weston Price studied hunterer-gatherer and agrarian socieites with zero access to modern food and medicine, and found them to be in excellent shape and condition, as far as he could ascertain, superior condition to ours in many cases and respects, and so perhaps even the medieval peasant, was living far longer than modern science supposes.
Maybe we haven't come half as far as we think we have.
