Re. point 2: I wish I had sources for this, but as I understand it, few adults have ever died in their 30s and 40s. We hear the average age was 35 in some periods of history, but I don't know how many scientists even said that, maybe it was reporters misunderstanding the point of the number, because to laymen it's a weird way of saying that "child mortality was high and disease was common". Once you were an adult and you didn't catch the plague, you lived to 60+.
