I'd be curious to know how old the author is, since the selection of 30 years to me points to biased analysis. As one likely knows that's spent any time researching the topic, and as others have committed, there's no evidence to support the author's claims. Historically speaking most people have been able to live as long as they do now on average. To my knowledge infant mortality was the big outliner historical speaking when it came to average life expectancy and points to why average life expectancy is a pour measure. Truth is that if there was a major leap, there's zero reason the general public would ever get wind of it; basic economic both in terms of it as a product and the impact it'd have on populations.
