I suspect the confounding variable is that late 20’s/early 30’s is when most people have kids. Happiness levels improve in late 50’s when kids are out of the house.
Kids may be “a complete joy and the best thing you’ve ever done”, but they’re also a huge financial burden, source of stress, and limiter on doing what you wanna do.
