Strauss and Howe speculated that turnings might be shortening rather
than lengthening, but weren't sure about it. My own finding is that
average turning and saeculum lengths are constant throughout history.
80 years appears to be an almost immutable constant for humans. It's
true that the average lifetime has increased (because of infant
mortality, for example), but the maximum life span seems to have been
relatively constant throughout history. For example, during the
Golden Age of Greece, Pericles lived 66 years, and Aristides lived 72
years -- not quite 80 years, but close enough to make the point.
Basically, there are always a few people in each generation who live
to be 70-80, and those are the elders who remember the last crisis,
and who protect everyone by counseling caution and compromise. It's
when the elders of the previous Artist generation die that society
loses all their wisdom at once, and the new crisis begins.
Sincerely,
