<i>&quot;Many more people are living in to their 70&#x27;s, 80&#x27;s and 90&#x27;s than previously in human history.&quot;</i><p>Correct, though largely (not entirely, but very largely) because the proportion of people living past age ~3 has skyrocketed. Correct for that factor, and our life expectancy is actually lower than it was in, say, mid-Victorian England.<p>(Note, as well, that I&#x27;m referring to life expectancy and not, say, the potential maximum human lifespan).
