The neuroscience here is more radical than people realize.

What you’re watching is a hormonal phase transition. Within minutes of skin-to-skin contact with a newborn, a father’s endocrine system starts a cascade that rewires his brain for the next 20 years.

Testosterone drops 34% on average. Gettler’s 2011 landmark study at Notre Dame tracked 624 men and found that the ones who spent 3+ hours per day in direct childcare had the steepest declines. This matters because testosterone and parental sensitivity are inversely correlated. Lower T predicts more responsiveness to infant cues, more physical touch, more synchrony with the child’s emotional states.

Meanwhile, oxytocin surges 33% above non-father baselines. Prolactin spikes. Estradiol rises. These are the same hormones that activate in mothers during pregnancy and breastfeeding. The entire “maternal bonding” cocktail fires in fathers through a different delivery mechanism: proximity and touch.

Here’s where it gets wild. Dr. Pilyoung Kim at the University of Denver scanned fathers’ brains at 2-4 weeks postpartum and again at 12-16 weeks. The regions linked to attachment, empathy, and threat detection showed measurable increases in gray and white matter. The brain physically bulked up in areas responsible for protection and caregiving.

And in mice studies, neurogenesis (new neuron formation) occurred in father brains within days of their pups being born. But only in fathers who stayed in the nest. The ones removed on day one showed zero new neuron growth. Physical contact was the switch.

So the claim about brains being “literally rewired for protection” actually undersells it. The father’s brain grows new tissue. It shifts its entire hormonal architecture from mating optimization to caregiving optimization. The reward circuitry that previously activated for sexual stimuli redirects toward child faces and infant cries.

The biological mechanism for fatherhood is one of the most aggressive neuroplastic events in the adult male lifespan. And it’s entirely dose-dependent: more contact, more holding, more time in proximity = stronger the neural and hormonal shift.

That first hold is a pharmacological event.

@devahaz Idk maybe read his patch that says SRT. A quick google search will answer your question about his gear that you find so unsettling.

To see American Warrior culture, we need to merge these two maps. The B&W is Woodard's eleven regional cultures of America. The green is the counties that have the highest percentages of military service.

Three cultures, Greater Appalachia, Deep South & Tidewater

In my life I’ve never met a man who doesn’t love Master and Commander. I cannot even comprehend this. “Pretentious”? Why? Because Iron Man never shows up? Because the ship doesn’t turn into a Transformer? Because the script was written above a 6th grade reading level?

Tolkien is unmatched

Just consider that this entire universe was once nothing but an idea in someone’s mind.

i think it would be way better if all our cities looked like this in the future

American, roman empire vibes ("greco-futurist"), space-age, and full of beauty and life

This picture is in a dollhouse.

A dear family friend (Dolores “Teedy” Lee) who died recently had been working on it for decades. She was an expert woodworker and passionate about antiques. Take a little tour!

@CJGRISHAM Hard to follow in the beginning with the lack of context. You displayed a DoD LEOSA ID and assumed local PD would immediately recognize it?
