Ah, yeah, that sounds like it was indeed just incorrect. To add to your comment about modern medicine. Keep in mind that when you isolate out infant mortality, you get an average life span of roughly 60-ish in ancient times. Present day mortality is closer to 85+ for the G7 countries and 75+ for other fairly well developed countries. That's a 25 year increase! Given those statistics, I would say modern medicine is actually doing quite a bit to improve life expectancy into your golden years!
