9-enders (nine-enders) explanation: people approaching their 30s, 40s and 50s, examining their lives for meaning and setting off skydiving, running marathons and climbing Everest

9-Enders (nine-enders)

Nine-enders are people in the last year of a decade, say, 29, 39, 49, 59. Adam Alter and Hal Hershfield, who introduced the term, propose that as we approach the end of a decade we are more likely to do a kind of "meaning audit" of our lives. And in the years just before the end of a decade, if we may have fallen short or feel there’s something else we want to accomplish, we’re much more likely to do it then than in any other year of a decade.

In practice, as Dan Pink shared in his book When: The Scientific Secrets of Perfect Timing, these are, therefore, the times when we’re more likely to do something extreme like running a marathon for the first time and, sadly, also committing suicide.

Take care out there.
