Undoubted, and as reflected in the differentials in survival between countires and continents.
Clean water, organised society, constant food supplies, better accomodation against the elements, inoculations etc undoubted progress.
And doubtless longer life spans are a factor.
But the huge increase in western diseases is an issue too, and many of those are striking younger and younger, and by all accounts not seen in certain sectors where they live a long time too.
Thanks for the thought provoking response.
