Explore the biology of stress, motivation, and status—through dopamine, testosterone, estrogen, and the amygdala’s rapid threat circuits.
In this episode, we map the full landscape of how stress and motivation arise in the brain and body. We start with the concept of stress as duration plus valence, showing how the amygdala makes split-second judgments about threat or opportunity before the conscious mind catches up. From there, we explore how testosterone amplifies status-driven behavior, not universally but context-specifically, and how behavior itself feeds back into hormone levels through the challenge hypothesis.
You’ll learn why dopamine is really about anticipation and pursuit—not pleasure—and how this shapes everything from ambition to social comparison. We also highlight the underappreciated role of estrogen as a neuroprotective and cardioprotective force, consistently buffering the brain and heart.
The episode closes with practical tools for regulating stress: controlling what you can, increasing predictability, building outlets, strengthening social support, and using reframing to shift perceived status threats. We also acknowledge the limits of advice under severe hardship and examine how the prefrontal cortex lets us choose healthier hierarchies—despite social media’s distortion of ancient status drives.
Listener Takeaways:
• How stress combines duration and valence
• Amygdala rapid threat and value assessment
• Testosterone’s status amplification & behavior loops
• Dopamine’s role in pursuit, not pleasure
• Tools for reframing and healthier hierarchies

SPEAKER_01 (00:00):
Welcome to the deep dive.
Today we're getting into thescience of stress, of
motivation, hormones, really thestuff that drives us.
We're going to try and give youa kind of biological shortcut.
SPEAKER_00 (00:11):
Yeah, our mission here is precision.
We have to cut through all the,you know, the myths around
molecules like testosterone andcortisol.
The key thing to remember isthat in biology, context is
everything.
SPEAKER_01 (00:22):
Aaron Powell It's not just an on-off switch.
SPEAKER_00 (00:24):
Exactly.
It's not on-off.
It's more like a set ofexquisitely tuned volume knobs.
And understanding what's turningthose knobs, that's the whole
game.
SPEAKER_01 (00:32):
Aaron Powell Right.
And for you, the learner, we'retrying to pin down the very
specific mechanisms that decideif an experien a high arousal
experience is terrifying or justexhilarating.
It's all about that idea ofvalence.
SPEAKER_00 (00:45):
Is it good or is it bad?
And that decision happens inwhat, milliseconds?
SPEAKER_01 (00:49):
So let's start with stress.
It always gets painted as thisvillain.
SPEAKER_00 (00:52):
The monolithic villain, right.
But it's not.
If you think about stress on twodifferent axes, like two graphs,
it gets a lot clearer.
Aaron Powell Okay.
SPEAKER_01 (00:59):
So the first axis would be duration.
SPEAKER_00 (01:01):
Aaron Powell Duration.
A little bit of short-termstress is actually good for you.
It can boost your immune system,sharpen your memory for a bit.
SPEAKER_01 (01:08):
But if you slide over into chronicles, that's the
daily grind, the horriblecommute that just never ends.
SPEAKER_00 (01:14):
That's the guaranteed downhill slope.
Yeah.
That's what causes real physicaldamage.
Yeah.
The micromanaging boss you haveto deal with for years.
That destroys the system.
SPEAKER_01 (01:23):
But then there's the second axis, balance, the good
versus the bad, because we don'twant to get rid of all stress.
SPEAKER_00 (01:29):
We pay for the right kind of stress.
We literally buy tickets for it.
We call it stimulation.
SPEAKER_01 (01:34):
Scary movies, roller coasters.
SPEAKER_00 (01:36):
A really hard crossword puzzle.
That's the stuff that makes usfeel alive.
And physiologically, it looksalmost the same as the bad
stuff.
SPEAKER_01 (01:43):
Right.
The heart rate's up, you'rebreathing fast, muscles are
tense, cortisol is spiking.
So if the body's response isidentical, how does the brain
know the difference between, youknow, pure joy and pure terror?
SPEAKER_00 (01:57):
It's a mechanical checkpoint.
Structure in the brain calledthe amygdala.
SPEAKER_01 (02:00):
The threat detection center.
SPEAKER_00 (02:02):
Exactly.
If the amygdala is part of thathigh arousal profile, if it's
firing, the brain instantly tagsthe experience as adverse.
It's bad.
SPEAKER_01 (02:12):
But if everything else is firing high, the heart
rate, everything but theamygdala is quiet.
SPEAKER_00 (02:17):
Then the brain logs it as excitement.
SPEAKER_01 (02:19):
Yeah.
SPEAKER_00 (02:19):
It's the decider.
Is this terror or is this fun?
SPEAKER_01 (02:22):
In that distinction, terror versus fun, that's all
interpretation.
So if the amygdala is theswitch, what's the volume knob?
I think that brings us totestosterone.
SPEAKER_00 (02:31):
Yeah, and this is probably the single biggest
biological myth out there.
The idea that testosterone ortea causes aggression.
SPEAKER_01 (02:38):
Everyone believes it.
We see the correlation malestend to have higher T, are
statistically more aggressive,and we just connect the dots.
SPEAKER_00 (02:45):
But the evidence is overwhelming now.
T doesn't create aggressionfrom, you know, a calm state.
It doesn't just invent it.
SPEAKER_01 (02:51):
So it's not the spark, it's the gasoline.
SPEAKER_00 (02:53):
That's a great way to put it.
It's an enhancer.
It dramatically lowers thethreshold for things that would
normally make you aggressive.
SPEAKER_01 (02:59):
Okay.
So if you're already prone tobeing competitive or a little
aggressive.
SPEAKER_00 (03:04):
Tea just makes it way easier for that behavior to
get triggered.
It turns up the volume onwhatever system is already
humming along.
Reactive aggression, sexualdrive, you name it.
It just amplifies what's alreadythere.
SPEAKER_01 (03:16):
Aaron Ross Powell, which leads to this fascinating
chicken and egg problem, thisparadox of cause and effect.
SPEAKER_00 (03:21):
Aaron Powell Right, because we assume high tea leads
to aggressive acts.
But it's actually the other wayaround, mostly.
SPEAKER_01 (03:28):
Aaron Powell The behavior drives the hormones.
SPEAKER_00 (03:30):
Yes.
Sexual activity, winning afight, any successful display of
dominance.
It raises your T levels and itdoes it fast.
Your baseline T on a Tuesdaymorning is barely predictive of
anything.
It's the context, the behavior,that causes the surge.
SPEAKER_01 (03:45):
And it's so psychological.
It doesn't even have to bephysical, like the studies on
sports fans.
SPEAKER_00 (03:49):
Oh, yeah.
If your team wins a huge game,that feeling of victory, of
status, is enough to raise yourT levels, even if you're just
sitting on your couch.
SPEAKER_01 (03:58):
So it's about the feeling of winning.
SPEAKER_00 (04:00):
It's the feeling of successful status defense.
You can see this so clearly inwhat they call the subtraction
studies.
When researchers remove thetestes, the main source of tea,
aggression, and sexual behavior,they drop a lot.
SPEAKER_01 (04:15):
Which at first glance looks like proof that T
causes it.
SPEAKER_00 (04:18):
Right.
But here's the kicker thebehaviors don't drop to zero,
they don't disappear entirely.
SPEAKER_01 (04:24):
And that's the key insight.
SPEAKER_00 (04:25):
That's everything.
Because the amount of behaviorthat's left over is predicted
almost perfectly by theindividual's prior history.
If an animal had a long learnedhistory of being aggressive to
get status, that behavior justkeeps coasting.
SPEAKER_01 (04:37):
It's just social conditioning at that point.
SPEAKER_00 (04:39):
Exactly.
It proves tea isn't necessaryfor the behavior, it just lowers
the barrier to entry.
It makes it easier to learn inpractice in the first place.
SPEAKER_01 (04:47):
So if tea is all about dominance and competition,
let's talk about status.
How does it work in our world,in the social hierarchy?
SPEAKER_00 (04:54):
This gets us to the challenge hypothesis.
The idea is that tea is secretedwhen you feel your status is
being challenged.
And it motivates you to dowhatever you need to do to hold
on to that status.
SPEAKER_01 (05:04):
Now for a baboon, that's pretty simple.
It means get aggressive, fight.
SPEAKER_00 (05:09):
Right.
But for humans, our statusmarkers are so abstract.
This is where the contextdependency just gets wild.
SPEAKER_01 (05:17):
You're talking about those economic game studies.
SPEAKER_00 (05:19):
A nutty prediction, yeah.
Yeah.
In these games, status wasn'tabout being aggressive.
Status was achieved by being themost generous, the most
trustworthy person in the group.
And when they gave people tea inthat context, it made them more
generous, more pro-social.
SPEAKER_01 (05:34):
That feels so backwards, though.
Why would the hormone ofdominance make you give things
away?
SPEAKER_00 (05:39):
Because tea is just amplifying the motivation for
social status, whatever therules of the game are.
In that context, generosity wasthe high status move to power
play.
SPEAKER_01 (05:49):
Like conspicuous consumption.
SPEAKER_00 (05:50):
Exactly.
You see it at those fancy schoolauctions, a bunch of you know
half-drunk alpha males trying tooutbid each other, writing these
huge checks.
The generosity is thecompetition.
Tea is just fueling thatspecific display of status.
SPEAKER_01 (06:03):
So it's the hormone of whatever gets you ahead
that's much more subtle.
And a big part of that isconfidence.
SPEAKER_00 (06:08):
A huge side effect is increased self-confidence,
which could be great, you know,better than some self-help
books.
But the problem is thatconfidence is often inaccurate.
SPEAKER_01 (06:19):
It makes you think you don't need help.
SPEAKER_00 (06:21):
Yeah.
I'm on top of this all on myown.
Yeah.
That's the tea mantra.
It makes people lesscooperative, it makes them
cocky, impulsive.
SPEAKER_01 (06:28):
And it skews your risk assessment.
SPEAKER_00 (06:30):
Totally.
And it leads to profoundmiscalculations.
I mean, some historians andbiologists have seriously
speculated that this kind oftea-driven overconfidence might
have played a role in startingWorld War I.
All these leaders were justabsolutely certain they'd win in
a few weeks.
SPEAKER_01 (06:44):
Okay, let's shift from T as the amplifier to the
motivation molecule itself,dopamine.
This is another one that needs aserious rewrite.
SPEAKER_00 (06:52):
Oh, a total revision.
Everyone thinks dopamine is thepleasure molecule.
The reward, it's not.
It's the chase.
It is 100% the chase.
It's the anticipation of thereward.
And maybe more importantly, it'swhat generates the goal-directed
behavior, the raw motivation togo get it.
SPEAKER_01 (07:09):
Like a gambler pulling the lever on the slot
machine.
The dopamine hit isn't the win,it's the pull, the hope.
SPEAKER_00 (07:16):
That's the core of it.
And this is why tea and dopamineare so synergistic.
Tea amps up that wholemotivation pathway.
SPEAKER_01 (07:23):
How does it do that physically?
SPEAKER_00 (07:25):
Well, tea increases energy, alertness, a sense of
awareness, but at a cellularlevel, it increases glucose
uptake into your skeletalmuscles.
SPEAKER_01 (07:35):
So it's literally fueling the muscles.
SPEAKER_00 (07:37):
Within minutes of its release, it's not just a
feeling.
Your body is physically primed,ready to act.
Tea makes sure that when youdecide to go for it, the
resources are there.
SPEAKER_01 (07:47):
So they're completely intertwined systems.
SPEAKER_00 (07:49):
Deeply.
You can see in lab studies, ratswill press a lever over and over
just to get a little infusion oftea into their bloodstream.
They're basicallyself-medicating to optimize that
dopamine release.
They're fueling the engine.
SPEAKER_01 (08:00):
Okay, so let's switch gears to a hormone that
often gets left out of theseconversations, but is uh just as
important estrogen.
SPEAKER_00 (08:07):
A hugely important protector.
I mean, if you look at the data,having a healthy, stable supply
of estrogen is one of the singlegreatest protective forces in
the body, especially for thebrain and the cardiovascular
system.
SPEAKER_01 (08:19):
It seems to have almost the opposite effect of
those really highnon-physiological levels of tea.
SPEAKER_00 (08:25):
It does.
Where tea can sometimes increaseinflammation, estrogen does the
opposite.
In the brain, it enhancescognition, but it also
stimulates neurogenesis.
SPEAKER_01 (08:36):
Which, for the listener, that means it's
actually helping to build newneurons.
SPEAKER_00 (08:40):
Rebuilding the infrastructure for memory,
especially in the hippocampus,it also boosts glucose and
oxygen delivery to the brain.
This is why a sustainedphysiological level of estrogen
is one of the strongestpredictors of protection against
things like Alzheimer's.
SPEAKER_01 (08:55):
And for the heart.
But the key here, and thesources were really clear on
this, is consistency.
It's not something you can justadd in late in life and expect a
miracle.
SPEAKER_00 (09:10):
No, consistency is everything.
The body thrives on thosepredictable optimal levels over
a long period of time.
SPEAKER_01 (09:16):
Okay, let's bring it all back to stress mitigation.
Back to that famous ratexperiment.
SPEAKER_00 (09:21):
The running wheel.
SPEAKER_01 (09:22):
Right.
Rat one is running because itwants to.
Rat two is forced to run on aconnected wheel doing the exact
same amount of work.
SPEAKER_00 (09:28):
Aaron Powell And Rat One gets all the amazing
benefits of exercise.
Lower heart rate, lessinflammation, neurogenesis.
Rat two, it gets all thedownsides of severe chronic
stress, elevated cortisol,inflammation, brain fog.
SPEAKER_01 (09:41):
It's the exact same physical act.
SPEAKER_00 (09:43):
Which is the undeniable proof.
It is purely the interpretationin your head, the sense of
control or the lack of it, thatdetermines the entire biological
outcome.
SPEAKER_01 (09:52):
Aaron Powell So the recipe for making stress less
stressful has to be aboutpsychology, about regaining
control.
SPEAKER_00 (09:59):
That's the foundation.
A sense of control andpredictability.
Those two things are massivelyprotective.
Then you need an outlet forfrustration.
SPEAKER_01 (10:05):
Aaron Powell Which, for a rat, is gnawing on a piece
of wood for humans.
SPEAKER_00 (10:09):
It's often displacement aggression, yelling
at someone lower on the totempole.
It reduces the stress for theaggressor, but it's responsible
for a ton of unhappiness in theworld.
SPEAKER_01 (10:18):
Okay, so control, predictability, outlet, and
social support.
Yeah.
SPEAKER_00 (10:22):
And finally, the ability to just cognitively
reframe something is good news.
The hooray interpretation.
SPEAKER_01 (10:28):
It sounds so simple on paper.
So why are so many people sooverwhelmed?
SPEAKER_00 (10:33):
And that is the huge critical caveat.
You can't preach these tools tosomeone who's in, for lack of a
better term, real hell.
SPEAKER_01 (10:42):
Terminal illness, homelessness.
SPEAKER_00 (10:44):
Right.
Telling someone in thatsituation they just need more
predictability.
It's privileged heartlessness.
SPEAKER_01 (10:49):
Yeah.
SPEAKER_00 (10:50):
It doesn't work when the external reality is that
crushing.
The methods are subtle.
SPEAKER_01 (10:55):
And they require practice.
Things like meditation,exercise, cold showers.
They work, but on average.
SPEAKER_00 (11:02):
And there are two big provisos.
One, it has to be a techniquethat actually works for you.
If meditating for 20 minutesmakes you want to scream, it's
just more stress.
SPEAKER_01 (11:11):
Find something else.
SPEAKER_00 (11:11):
Find something else.
And two, you can't save it forthe weekend.
The system needs that regulationconsistently, daily or every
other day for 20 or 30 minutes.
SPEAKER_01 (11:21):
And just making that decision is a huge part of it.
SPEAKER_00 (11:23):
Just deciding that your well-being is important
enough to stop the grind for afew minutes.
SPEAKER_01 (11:28):
Right.
SPEAKER_00 (11:28):
That's 80% of the battle right there.
SPEAKER_01 (11:30):
That choice, that prioritization, that's the human
brain at work, the prefrontalcortex, the PFC.
SPEAKER_00 (11:35):
The PFC is our evolutionary double-legged
sword.
You know, the deeper parts ofthe brain, the hypothalamus, the
amygdala, they're like hardwiredswitches.
Stimulate one neuron, an animalkills.
Stimulate another, it mates.
SPEAKER_01 (11:48):
But the PFC lets us plug anything into that system.
SPEAKER_00 (11:51):
Anything.
The shape of the earth, apolitical party, a brand of car.
We can make literally anythingthe object of our deepest fear
or our most profound love.
SPEAKER_01 (11:59):
Aaron Powell, which lets us play these psychological
games with status.
Being low in the hierarchy isterrible for your health, but
humans can be in more than one.
SPEAKER_00 (12:07):
Aaron Powell We can be in dozens, and that's our
buffer.
You can have a miserable lowstatus job, but be the captain
of the company softball team.
And you use your PFC to decidethe job is just for money.
The softball team.
That's what really matters.
SPEAKER_01 (12:21):
We also use it to protect our ego, the attribution
bias.
SPEAKER_00 (12:24):
Oh, constantly.
When we mess up, it was thesituation I was tired, I was
stressed.
When someone else does the exactsame thing, they're just a
rotten person.
That's who they are.
SPEAKER_01 (12:33):
And now this whole abstract system is being thrown
into overdrive by social media.
SPEAKER_00 (12:37):
It's being wicked out into infinity.
We evolved in little groups of150 people.
Now we scroll through thisendless landscape of perfect
bodies, genius intellects,exotic vacations.
It's a constant, never-endingstatus comparison across a
thousand different hierarchiesat once.
SPEAKER_01 (12:55):
Which brings us to the punchline of what it means
to be human.
SPEAKER_00 (12:58):
We're running on the exact same biological hardware
as every other animal, the samehormones, the same receptors,
the same primal drives.
But we apply that blueprint inthese bizarre abstract ways
across space and time.
SPEAKER_01 (13:10):
So a baboon gets stressed when a dominant male
steals its food right now.
SPEAKER_00 (13:15):
Right.
But we feel belittled because wesaw a movie character succeed,
or an expensive car drove past,or we read about a party in
Singapore we weren't invited to.
Our capacity for abstraction iswhat makes us feel inadequate in
ways no other creature on theplanet can.
SPEAKER_01 (13:28):
That really frames the modern challenge.
So the key lessons for you: stress is about interpretation (13:30):
undefined
and control.
Testosterone is acontext-dependent amplifier of
motivation, and estrogen is apowerful, crucial protector.
SPEAKER_00 (13:41):
And the final thought to leave you with,
thinking about that PFC.
If our ability to be in multiplehierarchies protects our health
by letting us find statussomewhere else, what happens
next?
What novel, maybe totallydigital hierarchies will our
brains invent in the future?
SPEAKER_01 (13:59):
Through VR or AI interactions.
SPEAKER_00 (14:01):
Purely for the purpose of mitigating the stress
of our real world failures.
How will the brain define statusin a context with no physical
body?
But that still triggers thatancient T dopamine system.
SPEAKER_01 (14:12):
That's a lot to think about.
Thank you for joining us on thisdeep dive.
We'll see you next time.

Because the amount of behaviorthat's left over is predicted
almost perfectly by theindividual's prior history.
If an animal had a long learnedhistory of being aggressive to
get status, that behavior justkeeps coasting.
SPEAKER_01 (04:37):
It's just social conditioning at that point.
SPEAKER_00 (04:39):
Exactly.
It proves tea isn't necessaryfor the behavior, it just lowers
the barrier to entry.
It makes it easier to learn inpractice in the first place.
SPEAKER_01 (04:47):
So if tea is all about dominance and competition,
let's talk about status.
How does it work in our world,in the social hierarchy?
SPEAKER_00 (04:54):
This gets us to the challenge hypothesis.
The idea is that tea is secretedwhen you feel your status is
being challenged.
And it motivates you to dowhatever you need to do to hold
on to that status.
SPEAKER_01 (05:04):
Now for a baboon, that's pretty simple.
It means get aggressive, fight.
SPEAKER_00 (05:09):
Right.
But for humans, our statusmarkers are so abstract.
This is where the contextdependency just gets wild.
SPEAKER_01 (05:17):
You're talking about those economic game studies.
SPEAKER_00 (05:19):
A nutty prediction, yeah.
Yeah.
In these games, status wasn'tabout being aggressive.
Status was achieved by being themost generous, the most
trustworthy person in the group.
And when they gave people tea inthat context, it made them more
generous, more pro-social.
SPEAKER_01 (05:34):
That feels so backwards, though.
Why would the hormone ofdominance make you give things
away?
SPEAKER_00 (05:39):
Because tea is just amplifying the motivation for
social status, whatever therules of the game are.
In that context, generosity wasthe high status move to power
play.
SPEAKER_01 (05:49):
Like conspicuous consumption.
SPEAKER_00 (05:50):
Exactly.
You see it at those fancy schoolauctions, a bunch of you know
half-drunk alpha males trying tooutbid each other, writing these
huge checks.
The generosity is thecompetition.
Tea is just fueling thatspecific display of status.
SPEAKER_01 (06:03):
So it's the hormone of whatever gets you ahead
that's much more subtle.
And a big part of that isconfidence.
SPEAKER_00 (06:08):
A huge side effect is increased self-confidence,
which could be great, you know,better than some self-help
books.
But the problem is thatconfidence is often inaccurate.
SPEAKER_01 (06:19):
It makes you think you don't need help.
SPEAKER_00 (06:21):
Yeah.
I'm on top of this all on myown.
Yeah.
That's the tea mantra.
It makes people lesscooperative, it makes them
cocky, impulsive.
SPEAKER_01 (06:28):
And it skews your risk assessment.
SPEAKER_00 (06:30):
Totally.
And it leads to profoundmiscalculations.
I mean, some historians andbiologists have seriously
speculated that this kind oftea-driven overconfidence might
have played a role in startingWorld War I.
All these leaders were justabsolutely certain they'd win in
a few weeks.
SPEAKER_01 (06:44):
Okay, let's shift from T as the amplifier to the
motivation molecule itself,dopamine.
This is another one that needs aserious rewrite.
SPEAKER_00 (06:52):
Oh, a total revision.
Everyone thinks dopamine is thepleasure molecule.
The reward, it's not.
It's the chase.
It is 100% the chase.
It's the anticipation of thereward.
And maybe more importantly, it'swhat generates the goal-directed
behavior, the raw motivation togo get it.
SPEAKER_01 (07:09):
Like a gambler pulling the lever on the slot
machine.
The dopamine hit isn't the win,it's the pull, the hope.
SPEAKER_00 (07:16):
That's the core of it.
And this is why tea and dopamineare so synergistic.
Tea amps up that wholemotivation pathway.
SPEAKER_01 (07:23):
How does it do that physically?
SPEAKER_00 (07:25):
Well, tea increases energy, alertness, a sense of
awareness, but at a cellularlevel, it increases glucose
uptake into your skeletalmuscles.
SPEAKER_01 (07:35):
So it's literally fueling the muscles.
SPEAKER_00 (07:37):
Within minutes of its release, it's not just a
feeling.
Your body is physically primed,ready to act.
Tea makes sure that when youdecide to go for it, the
resources are there.
SPEAKER_01 (07:47):
So they're completely intertwined systems.
SPEAKER_00 (07:49):
Deeply.
You can see in lab studies, ratswill press a lever over and over
just to get a little infusion oftea into their bloodstream.
They're basicallyself-medicating to optimize that
dopamine release.
They're fueling the engine.
SPEAKER_01 (08:00):
Okay, so let's switch gears to a hormone that
often gets left out of theseconversations, but is uh just as
important estrogen.
SPEAKER_00 (08:07):
A hugely important protector.
I mean, if you look at the data,having a healthy, stable supply
of estrogen is one of the singlegreatest protective forces in
the body, especially for thebrain and the cardiovascular
system.
SPEAKER_01 (08:19):
It seems to have almost the opposite effect of
those really highnon-physiological levels of tea.
SPEAKER_00 (08:25):
It does.
Where tea can sometimes increaseinflammation, estrogen does the
opposite.
In the brain, it enhancescognition, but it also
stimulates neurogenesis.
SPEAKER_01 (08:36):
Which, for the listener, that means it's
actually helping to build newneurons.
SPEAKER_00 (08:40):
Rebuilding the infrastructure for memory,
especially in the hippocampus,it also boosts glucose and
oxygen delivery to the brain.
This is why a sustainedphysiological level of estrogen
is one of the strongestpredictors of protection against
things like Alzheimer's.
SPEAKER_01 (08:55):
And for the heart.
But the key here, and thesources were really clear on
this, is consistency.
It's not something you can justadd in late in life and expect a
miracle.
SPEAKER_00 (09:10):
No, consistency is everything.
The body thrives on thosepredictable optimal levels over
a long period of time.
SPEAKER_01 (09:16):
Okay, let's bring it all back to stress mitigation.
Back to that famous ratexperiment.
SPEAKER_00 (09:21):
The running wheel.
SPEAKER_01 (09:22):
Right.
Rat one is running because itwants to.
Rat two is forced to run on aconnected wheel doing the exact
same amount of work.
SPEAKER_00 (09:28):
Aaron Powell And Rat One gets all the amazing
benefits of exercise.
Lower heart rate, lessinflammation, neurogenesis.
Rat two, it gets all thedownsides of severe chronic
stress, elevated cortisol,inflammation, brain fog.
SPEAKER_01 (09:41):
It's the exact same physical act.
SPEAKER_00 (09:43):
Which is the undeniable proof.
It is purely the interpretationin your head, the sense of
control or the lack of it, thatdetermines the entire biological
outcome.
SPEAKER_01 (09:52):
Aaron Powell So the recipe for making stress less
stressful has to be aboutpsychology, about regaining
control.
SPEAKER_00 (09:59):
That's the foundation.
A sense of control andpredictability.
Those two things are massivelyprotective.
Then you need an outlet forfrustration.
SPEAKER_01 (10:05):
Aaron Powell Which, for a rat, is gnawing on a piece
of wood for humans.
SPEAKER_00 (10:09):
It's often displacement aggression, yelling
at someone lower on the totempole.
It reduces the stress for theaggressor, but it's responsible
for a ton of unhappiness in theworld.
SPEAKER_01 (10:18):
Okay, so control, predictability, outlet, and
social support.
Yeah.
SPEAKER_00 (10:22):
And finally, the ability to just cognitively
reframe something is good news.
The hooray interpretation.
SPEAKER_01 (10:28):
It sounds so simple on paper.
So why are so many people sooverwhelmed?
SPEAKER_00 (10:33):
And that is the huge critical caveat.
You can't preach these tools tosomeone who's in, for lack of a
better term, real hell.
SPEAKER_01 (10:42):
Terminal illness, homelessness.
SPEAKER_00 (10:44):
Right.
Telling someone in thatsituation they just need more
predictability.
It's privileged heartlessness.
SPEAKER_01 (10:49):
Yeah.
SPEAKER_00 (10:50):
It doesn't work when the external reality is that
crushing.
The methods are subtle.
SPEAKER_01 (10:55):
And they require practice.
Things like meditation,exercise, cold showers.
They work, but on average.
SPEAKER_00 (11:02):
And there are two big provisos.
One, it has to be a techniquethat actually works for you.
If meditating for 20 minutesmakes you want to scream, it's
just more stress.
SPEAKER_01 (11:11):
Find something else.
SPEAKER_00 (11:11):
Find something else.
And two, you can't save it forthe weekend.
The system needs that regulationconsistently, daily or every
other day for 20 or 30 minutes.
SPEAKER_01 (11:21):
And just making that decision is a huge part of it.
SPEAKER_00 (11:23):
Just deciding that your well-being is important
enough to stop the grind for afew minutes.
SPEAKER_01 (11:28):
Right.
SPEAKER_00 (11:28):
That's 80% of the battle right there.
SPEAKER_01 (11:30):
That choice, that prioritization, that's the human
brain at work, the prefrontalcortex, the PFC.
SPEAKER_00 (11:35):
The PFC is our evolutionary double-legged
sword.
You know, the deeper parts ofthe brain, the hypothalamus, the
amygdala, they're like hardwiredswitches.
Stimulate one neuron, an animalkills.
Stimulate another, it mates.
SPEAKER_01 (11:48):
But the PFC lets us plug anything into that system.
SPEAKER_00 (11:51):
Anything.
The shape of the earth, apolitical party, a brand of car.
We can make literally anythingthe object of our deepest fear
or our most profound love.
SPEAKER_01 (11:59):
Aaron Powell, which lets us play these psychological
games with status.
Being low in the hierarchy isterrible for your health, but
humans can be in more than one.
SPEAKER_00 (12:07):
Aaron Powell We can be in dozens, and that's our
buffer.
You can have a miserable lowstatus job, but be the captain
of the company softball team.
And you use your PFC to decidethe job is just for money.
The softball team.
That's what really matters.
SPEAKER_01 (12:21):
We also use it to protect our ego, the attribution
bias.
SPEAKER_00 (12:24):
Oh, constantly.
When we mess up, it was thesituation I was tired, I was
stressed.
When someone else does the exactsame thing, they're just a
rotten person.
That's who they are.
SPEAKER_01 (12:33):
And now this whole abstract system is being thrown
into overdrive by social media.
SPEAKER_00 (12:37):
It's being wicked out into infinity.
We evolved in little groups of150 people.
Now we scroll through thisendless landscape of perfect
bodies, genius intellects,exotic vacations.
It's a constant, never-endingstatus comparison across a
thousand different hierarchiesat once.
SPEAKER_01 (12:55):
Which brings us to the punchline of what it means
to be human.
SPEAKER_00 (12:58):
We're running on the exact same biological hardware
as every other animal, the samehormones, the same receptors,
the same primal drives.
But we apply that blueprint inthese bizarre abstract ways
across space and time.
SPEAKER_01 (13:10):
So a baboon gets stressed when a dominant male
steals its food right now.
SPEAKER_00 (13:15):
Right.
But we feel belittled because wesaw a movie character succeed,
or an expensive car drove past,or we read about a party in
Singapore we weren't invited to.
Our capacity for abstraction iswhat makes us feel inadequate in
ways no other creature on theplanet can.
SPEAKER_01 (13:28):
That really frames the modern challenge.
So the key lessons for you: stress is about interpretation (13:30):
undefined
and control.
Testosterone is acontext-dependent amplifier of
motivation, and estrogen is apowerful, crucial protector.
SPEAKER_00 (13:41):
And the final thought to leave you with,
thinking about that PFC.
If our ability to be in multiplehierarchies protects our health
by letting us find statussomewhere else, what happens
next?
What novel, maybe totallydigital hierarchies will our
brains invent in the future?
SPEAKER_01 (13:59):
Through VR or AI interactions.
SPEAKER_00 (14:01):
Purely for the purpose of mitigating the stress
of our real world failures.
How will the brain define statusin a context with no physical
body?
But that still triggers thatancient T dopamine system.
SPEAKER_01 (14:12):
That's a lot to think about.
Thank you for joining us on thisdeep dive.
We'll see you next time.
