"We’re living longer now than we’ve ever had. 300K years ago, humans lasted about 40 years."

Yeah, longer life expectancy in the modern age, with a 21st century diet including a lot of cooked food... but, then you go on to rant about how back in the good old days people ate their meat rare or raw (which is healthier). Great way to prove your own premise.

Anyway, no people did not die of ill health in their 40s in ancient times, it was more like high infant mortality before age 5 + high maternal mortality in giving birth (prior to the invention of obstetrics), which claimed many young women + high levels of warfare and violence which ended many young men's lives. People still lived into their 80s in ancient times. Sophocles made it to 92 years old.

And of course, you've failed to respond to my point that if cooked food caused so many problems then earth should be dominated by cultures that were smart enough to eat their food raw and live longer/healthier. In recorded history, from Rome to medieval Europe, people usually cooked their meats. We know Mesoamericans did too, from archaeological evidence of their cooking pots, cooked food is such a bad idea and makes you sick, but it was invented independently on both sides of the Atlantic, not to mention among Australian aboriginals. What gives?
