Source Grounding & Lifespan Dynamics Model Analysis
"People around 35 to 40 start getting bored with life. It's partly because new stimuli decrease, but at that time, what helps you out is raising kids. And even after quitting work around 65, what keeps helping you is the presence of grandkids." — @TomoEqual
Model Insights: Raw novelty stimulus (travel, career firsts, rapid learning) naturally drops as patterns become predictable around age 35–40. Without intergenerational transfers or intentional community bonds, subjective satisfaction experiences a dip ("U-shaped curve"). Raising children and spending time with grandchildren or mentees creates a persistent secondary satisfaction wave that cushions mid-life drops and sustains post-retirement happiness well beyond age 65.
