Sorry, my comment isn't about how people would die post-apocalypse, it was about you saying that 80-90 percent of people died before age five before the year 1900 which is much higher than reality (probably about 30% in the middle ages, less then that in the 1800s) and also your assertion that if they survived to adulthood they lived to 80 at a similar rate as today when in fact it was much less common.
