>>18312008what a <1 IQ take
People didn't consistently die at 40. It is an average. Many men died while hunting or war, infection or infancy. This gives you the lower average. But otherwise people actually lived to be very old, if they were careful. And their skull had a full set of teeth, these people were healthier than you, with all your dumb vaccines.
Also keep in mind much of the lower life expectancy in the past is not from hunger gatherer times, bur rather the first modern cities without proper sanitation. Quite literally they were living in shit. A lot of the diseases disappeared with sanitation (not vaccines). A pretty good proof that diseases have more to do with sanitation than vaccines is that liberal cities like LA that allow bums to aglomérate and shit on the street, actually began bringing back many diseases that were "eradicated by vaccines". Fact: vaccines were always introduced after the fact, vaccines have never eradicated a disease in human history.
