Here's my math for why most people have never been 20: Of the first 100 billion people who lived, at least half (the most prominent researchers in the field consider that estimate on the low end) of people died before 15. Counting the 3% or so who died between 15 and 20, that means that probably at least 53 billion of the first 100 billion people died before the age of 20. Of the most recent 10 billion who died (most of whom were born between 1800 and 1950), over 30% died before the age of 20. That takes us to a conservative estimate of 56 billion of the 110 billion people who've died so far. (2.6 billion people are CURRENTLY under the age of 20, so even if you look at the entire population of humans, it is probable that most people have never been 20--hence the title.)
