This is the one that drives me nuts. "hey there my guy did you know the average life expectancy in the middle ages was 30? everyone in europe was illiterate haha whites dumb lmoa" Childbirth is a terrifying thing, a lot can go wrong very easily especially with malnutrition or unclean water. There was a very high infant mortality rate in those times which meant perhaps for every 1 person that made it to adulthood 1 would die (i dont know the real numbers so dont take my word for it) which would halve the average life expectancy making a population that lives on average to 80 statistically only live to 40, then throw in medieval warfare and you have another few years off the average life expectancy. Also illiteracy had nothing to do with intelligence, it just wasnt necessary at the time. Reading was a luxury to most, people who spent their daily lives working land didnt need to read shit, you could get most of the information you needed by word of mouth and i suspect communities were far more close knit in those days too. The perversion of history has been a high priority for jews.
