  • Okay, source it if you’ve got it, because the idea that a single study ran out of funding at 25 and that’s where the number comes from is such an odd suggestion, as though no one else has studied the brain’s development and neuroscientists everywhere just shrugged and thought, “if only the funding were there.”

    Here’s a well-sourced article that concludes the brain continues to develop well into the mid-20’s.

    While the brain will always continue to develop and grow, due to neuroplasticity, the concern is whether or not the prefrontal cortex, the part of the brain responsible for long-term decision making, is properly developed. This development continues into the mid-20’s and is well-documented.

    Here’s a 2022 study where they looked at over 100,000 brain scans from people 110 days old to over 100 years old used to draw and affirm similar conclusions.

    While 25 isn’t magic number, as everyone’s brains develop on different timelines, it is a rational and reasonable landmark that can be reliably used for broad discussions.

    Here’s more from the National Institute of Mental Health and Penn Medicine.


  • I’ll disagree about age. At 23, the pre-frontal cortex is still developing and won’t be finished until around 25.

    It’s responsible for:

    • Executive functions (planning, decision-making, problem-solving)
    • Impulse control
    • Emotional regulation
    • Social interactions and behavior

    There is a distinct imbalance between someone in their 60’s and someone in their early 20’s. I’m not saying it can’t be carefully and respectfully navigated, but it has to be acknowledged and accounted for.

    It doesn’t sound like that happened here.

    Then we have the power dynamic of a celebrity who is also your employer. Add in a healthy dose of fictive kinship due to the live-in nature of a nanny and you’re in a situation rife with the potential for abuse.
