But, I've said all that before. And the common demographic boomer dates like what you cite are not boomer generation dates.
Lifespans are increasing, not decreasing, so saecula may be increasing in length and slowing down. 72 today probably applies to poorer countries, not the USA; still less to Western Europe.
72 years being one's average lifespan applies worldwide.
