I wonder if the changes at 66 align with retirement age more than anything hardwired.
I’ve watched many people age into their 60s, and the most significant changes in their happiness and behavior are associated with retirement.
Also convinced they're observing a correlation with this rather than something age specific. It's like exercise, it's really impressive how people who stay active in their late years can still be very fit way into their 80s or 90s, yet if one stops trying it just crumbles away.

32 could easily be aligned with parenthood
This makes sense. My old boss retired at 60. He doesn't need to work anymore and spends all of his time going on cruises and at the beach. This has to have a major change on your brain.
