> Average life expectancy in Iron Age France (from 800 B.C.E. to about 100 C.E.) has been estimated at only 10 or 12 years. Doesn't that sound extremely weird? Like, how does puberty, and 9 months to have a baby, fit in with a 12 year total life expectancy? Maybe I need more coffee or something...

#35Wondering how many will ever be born here, if it lasts until the sun dries out for example
The Doomsday Argument[0] relates to this. It says that since the reader is born in the current times with there being X billion humans so far, statisticslly there shouldn't be too many more (not say tens of trillions). I don't think the logic is too sound though. Or rather that the premises should be taken for granted. [0] https://en.wikipedia.org/wiki/Doomsday_argument

#36Makes me wonder how many more billions will have to die before we bother to put some actual effort into ending death, but I know that's a very obscure opinion. https://nickbostrom.com/fable/dragon

That average, there are people life longer than that.

I think this is a case where an average value cloaks the distribution. Consider very high infant and childhood mortality rates, and how that might skew the average value.
