Saturday Human Crimes: The Physiology Behind the Behavior

🔥

Cats commit crimes (see my cat crimes post) and so do humans. But the human ones are quieter. Sneakier. Harder to spot unless you know what you’re looking for.

Cats knock things off counters. Humans knock themselves off balance.

Cats commit chaos in daylight. Humans commit theirs in the nervous system.

There’s a crime almost every human commits, not publicly, not loudly, not in a way anyone else would notice. It happens in the pauses. In the micro‑moments. In the places where your body speaks before your mind catches up.

You think it’s a habit. A flaw. A personality quirk.

It isn’t. It’s a physiological glitch, a survival script your body wrote long before you had language for it.

It shows up as:

the snack you didn’t mean to eat
the message you didn’t send
the spiral you didn’t choose
the exhaustion you can’t explain
the reaction you regret before it’s even over

Everyone thinks they’re alone in it. Everyone thinks it’s “just them.”

Everyone thinks they should be able to control it.

But there’s a reason you can’t. A reason no one ever told you. A reason that makes the whole thing make sense in a way that feels, unsettling.

Some of us have been studying these crimes. Not to judge them. But to decode the language underneath, the one the body has been speaking this whole time.

There’s a place where these patterns finally make sense. Where physiology becomes a map instead of a mystery. Where the “why am I like this?” finally gets an answer.

1. Emotional Eating in the First Degree

This isn’t about “comfort food.” This is about metabolic triage.

When your blood sugar drops, your body enters a state called neuroglycopenia — meaning your brain isn’t getting enough glucose to function. Your brain has ONE job: keep you alive. So it does what any panicked CEO would do — it fires the entire executive team (your prefrontal cortex) and hands the keys to the intern (your amygdala).

The amygdala has two strategies:

Find safety
Find calories

This is why you don’t crave broccoli. You crave fast carbs, the metabolic equivalent of calling 911.

Add cortisol to the mix and your body becomes a calorie-seeking missile. Cortisol increases appetite, slows digestion, and makes your brain hyper-focus on food cues.

This is not emotional weakness. This is survival physiology misfiring in a modern world with 24/7 access to snacks.

Your blood sugar drops 12 points and suddenly you’re in the pantry like a raccoon with a gambling problem. Your amygdala is screaming, “WE’RE DYING,” while your prefrontal cortex is tied up in the basement. This isn’t emotional eating. This is metabolic hostage negotiation with snacks as the negotiators.

2. Ghosting Texts You Mentally Replied To

This is not a personality flaw. This is a working memory + nervous system collision.

Your working memory can only hold about 4–7 pieces of information at once. When you’re stressed, overwhelmed, or in a mild freeze response, your working memory collapses to 1–2 items.

So when a text comes in, your brain does this:

Reads it
Generates a response
Files it under “completed”
Never actually sends it

Why? Because your nervous system is prioritizing threat management, not communication.

If your vagus nerve is in a freeze or fawn state, initiating ANY action — even a text — feels like climbing a mountain.

This is why you can write a dissertation in your head… and still leave someone on read for three days.

You wrote the perfect reply, in your mind. Your nervous system said, “We’re overwhelmed, babe,” and filed the message under “Completed Tasks That Never Actually Happened.” Your vagus nerve basically hit “airplane mode” on your social life.

3. Procrastination with Intent to Overwhelm

Procrastination is not laziness. It’s a dopamine economy problem.

Dopamine is not the “pleasure chemical.” It’s the motivation chemical, the thing that helps you initiate tasks.

Low dopamine =

tasks feel heavier
starting feels impossible
everything feels like wading through wet cement

But here’s the twist: When a deadline approaches, your body releases adrenaline. Adrenaline temporarily compensates for low dopamine by increasing focus, urgency, and energy.

This is why you suddenly become a productivity machine at 11:58 PM. Your body is using stress hormones as a substitute for motivation.

It’s not a character flaw. It’s a neurochemical workaround.

Your dopamine is on strike. Your adrenaline is the intern doing everyone’s job at 11:59 PM. You’re not procrastinating, you’re waiting for your emergency hormones to clock in because they’re the only ones who get results.

4. Snapping at Someone You Love

This is not “being dramatic.” This is limbic system hijack.

When your stress load exceeds your capacity, your brain shifts into survival mode. Your prefrontal cortex — the part responsible for emotional regulation, goes offline.

Your limbic system takes over. The limbic system has the emotional range of a toddler with a juice box:

reactive
impulsive
dramatic
loud

Cortisol also reduces your ability to read facial expressions accurately. So you interpret neutral cues as threats. A sigh becomes criticism. A question becomes an attack. A pause becomes rejection.

You’re not “losing it.” Your physiology is misinterpreting safety as danger.

Your cortisol hit the ceiling and your limbic system said, “We ball.” Your prefrontal cortex tried to intervene but was escorted out of the building by security. You didn’t mean to snap, your physiology just filed for temporary insanity.

5. Overthinking Every Possible Scenario

Overthinking is not a mindset issue. It’s a threat‑simulation algorithm.

Your brain evolved to predict danger, not happiness. It runs simulations to keep you alive: “What if this goes wrong?” “What if they’re upset?” “What if I fail?” “What if I embarrass myself?”

This is your default survival software.

When your nervous system is dysregulated, this simulation loop becomes louder and more frequent. Your amygdala flags everything as “potential threat.” Your prefrontal cortex tries to solve it. Your body gets stuck in a feedback loop of imagined danger.

You’re not “too sensitive.” You’re running ancient wiring in a modern world.

Your brain is running a full Marvel multiverse of imaginary disasters. Your amygdala is like, “What if they hate you?” Your prefrontal cortex is like, “They literally just said ‘okay.’” You’re not dramatic, you’re running ancient predator software on modern WiFi.

6. Doomscrolling Until Your Soul Leaves Your Body

This isn’t a lack of discipline. This is neurobiology doing parkour.

Your brain is wired to scan for:

novelty (dopamine)
threat (amygdala activation)
social cues (oxytocin pathways)

Every swipe is a slot machine:

Will it be funny?
Horrifying?
Outrageous?
Relatable?
Disastrous?

Your dopamine system LOVES unpredictability, it’s the same mechanism behind gambling addiction. Meanwhile, your amygdala is scanning for danger because it thinks knowing about threats = survival.

So doomscrolling is not self-sabotage. It’s your ancient survival software colliding with modern infinite content.

Your thumb is doing laps like it’s training for the Olympics. Your dopamine is chasing novelty like a toddler on Red Bull. Your amygdala is scanning for threats like it’s auditioning for CSI. You’re not doomscrolling, you’re performing a neurological triathlon.

7. Saying “I’m Fine” While Actively Dying Inside

This is not emotional dishonesty. This is fawn response physiology.

When your nervous system senses relational threat, conflict, disappointment, judgment, it activates the fawn response:

appease
smooth over
minimize your needs
maintain connection at all costs

Your vagus nerve is trying to keep you safe by keeping the peace. Your cortisol is whispering, “Don’t rock the boat.” Your prefrontal cortex is offline, so you default to the safest script you know: “I’m fine.”

This isn’t avoidance. It’s survival through compliance.

Your vagus nerve is in fawn mode like, “Lie. Lie immediately.” Your cortisol is whispering, “If we tell the truth, we perish.” You’re not fine, you’re emotionally buffering like a 2007 YouTube video.

8. Replaying Conversations from 2014 at 2 AM

This is not overthinking. This is a threat audit.

Your hippocampus stores memories. Your amygdala tags them with emotional significance. When cortisol is elevated at night, the amygdala reopens old files to “review” them.

Your brain is trying to:

detect past mistakes
prevent future danger
rehearse better outcomes
avoid shame or rejection

It’s a primitive survival loop: “If I analyze this enough, I’ll never be hurt again.”

You’re not stuck in the past. Your physiology is trying to predict the future.

Your hippocampus is like, “Let’s revisit that awkward moment from 12 years ago.” Your amygdala is like, “Great idea.” Your prefrontal cortex is asleep. You’re not overthinking, you’re running a midnight shame marathon.

9. Buying 14 Self-Help Books and Reading None

This is not inconsistency. This is dopamine misdirection.

Dopamine spikes during:

anticipation
planning
imagining a better version of yourself

Buying the book gives you the neurochemical reward your brain wanted. Reading it requires:

executive function
sustained attention
delayed gratification

If your dopamine baseline is low, the motivation evaporates after the purchase. Your brain got the “future improvement” hit, so the follow-through feels unnecessary.

This is not failure. It’s reward circuitry confusion.

You love the idea of improvement. Your dopamine loves the purchase of improvement. Your executive function loves… naps. You’re not inconsistent, you’re collecting self-help books like Pokémon.

10. Overcommitting to Everything, Then Resenting Everyone

This is not people-pleasing. This is attachment physiology.

When your nervous system fears rejection or abandonment, it pushes you to say yes. Your cortisol says: “Agree now, survive the moment.” Your prefrontal cortex says later: “We don’t have the capacity for this.”

The resentment isn’t about the task. It’s about the physiological cost of overriding your boundaries.

This is not a personality flaw. It’s survival-driven overfunctioning.

You say yes like you’re auditioning for “America’s Next Top People-Pleaser.” Then your prefrontal cortex wakes up like, “WHO AGREED TO THIS?” You’re not flaky, you’re a boundaryless golden retriever with burnout.

11. Cleaning the Entire House Instead of Doing the One Thing You Need to Do

This is not avoidance. This is dopamine triage.

Your brain categorizes tasks by:

emotional risk
cognitive load
reward potential

The “one thing you need to do” usually carries emotional weight, uncertainty, vulnerability, or potential failure. Your nervous system flags it as a threat.

Cleaning, however, is:

predictable
controllable
instantly rewarding

Your physiology is choosing safe dopamine over risky dopamine.

Your brain: “We need to send that email.” Your nervous system: “What if we… reorganize the spice cabinet instead?” You’re not avoiding, you’re procrastinating productively like a gifted child with anxiety.

12. Googling Symptoms Until You’re Diagnosed with 7 Rare Diseases

This is not anxiety spiraling. This is hypervigilance physiology.

When cortisol is high, your brain becomes threat-sensitive. Every sensation gets amplified. Your interoceptive system (body awareness) becomes louder. Your amygdala interprets normal sensations as danger.

Googling becomes a way to:

reduce uncertainty
regain control
prepare for worst-case scenarios

But the search results trigger more cortisol, which increases hypervigilance, which sends you back to Google.

It’s a biochemical loop, not a personality flaw.

You felt one weird tingle and your amygdala said, “Open Google. Immediately.” Now you’re convinced you have a condition only 14 people in Antarctica have ever had. You’re not anxious, you’re doing community theater with your nervous system.

13. Starting 12 Projects and Finishing None

This is not inconsistency. This is dopamine-driven initiation + executive dysfunction.

Starting something new gives you:

novelty dopamine
creative stimulation
possibility energy

Finishing requires:

sustained attention
delayed gratification
prefrontal cortex endurance

If your dopamine dips mid-project, your brain seeks the next novelty hit. It’s not that you can’t finish. It’s that your physiology is rewarding beginnings more than endings.

Your dopamine loves beginnings. Your executive function hates endings. You’re not inconsistent, you’re a visionary with the follow-through of a goldfish.

14. Taking Things Personally That Had Nothing to Do with You

This is not sensitivity. This is social threat hyperactivation.

Humans are wired for belonging. Rejection once meant death. So your nervous system scans constantly for social cues.

When you’re stressed or dysregulated, your brain misreads:

tone
silence
pauses
facial expressions

Your amygdala flags neutral cues as danger. Your physiology is trying to protect you from exclusion, even when no threat exists.

This is ancient wiring in a modern social landscape.

Someone sighed and your amygdala said, “They hate us.” Someone paused and your nervous system said, “We’re being abandoned.” You’re not sensitive, you’re running social threat software on expert mode.

15. Avoiding Rest Because You Don’t Feel Like You “Deserve” It

This is not self-neglect. This is stress chemistry addiction.

When cortisol and adrenaline become your baseline, rest feels foreign. Your body interprets stillness as vulnerability. Your nervous system says: “Stay alert. Stay productive. Stay safe.”

Rest requires a parasympathetic shift, but if your body hasn’t felt safe in that state for a long time, it will resist it.

You’re not avoiding rest. Your physiology is avoiding perceived danger.

Your cortisol is your emotional support animal. Your adrenaline is your personality. Rest feels like betrayal. You’re not avoiding rest, you’re chemically loyal to chaos.

Functional medicine doesn’t “fix” these Human Crimes, it translates them. It takes the shame-soaked, moralized, self-blaming behaviors of modern humans and reframes them as physiology doing its best with terrible instructions.

1. Emotional Eating

Functional Medicine says: This isn’t a willpower issue. It’s a blood sugar, cortisol, and mitochondrial communication issue. We stabilize glucose, support adrenal rhythms, and rebuild metabolic flexibility. When the body stops panicking, the pantry stops calling.

2. Ghosting Texts You Replied to in Your Mind

Functional Medicine says: This is a working memory + vagus nerve + overwhelm problem. We support the parasympathetic system, reduce inflammation, and stabilize the HPA axis. When your nervous system feels safe, you can hit “send” in real life, not just in your imagination.

3. Procrastination

Functional Medicine says: This is a dopamine economy collapse. We look at nutrient cofactors (iron, B6, magnesium), sleep cycles, circadian rhythm, and mitochondrial output. When dopamine rises, initiation stops feeling like climbing Everest.

4. Snapping at Loved Ones

Functional Medicine says: This is limbic hijack due to cortisol dysregulation. We lower inflammatory load, stabilize blood sugar, support sleep, and retrain the stress response. When cortisol chills, so do you.

5. Overthinking Everything

Functional Medicine says: This is a threat physiology loop. We repair gut–brain signaling, reduce histamine load, support micronutrients, and regulate the vagus nerve. When the body feels safe, the brain stops running disaster simulations.

6. Doomscrolling

Functional Medicine says: This is a novelty-seeking dopamine loop + stress hypervigilance. We support dopamine pathways, reduce inflammation, and calm the amygdala. When your brain isn’t starving for stimulation or scanning for danger, the phone loses its hypnotic power.

7. Saying “I’m Fine” While Dying Inside

Functional Medicine says: This is fawn response physiology, a survival pattern. We regulate the nervous system, address trauma-patterned wiring, and support oxytocin pathways. When your body feels safe, honesty stops feeling dangerous.

8. Replaying Conversations from 2014

Functional Medicine says: This is amygdala hyperactivation + cortisol spikes at night. We stabilize circadian rhythm, support GABA pathways, and reduce neuroinflammation. When the brain isn’t inflamed, it stops hosting midnight shame marathons.

9. Buying Self-Help Books You Never Read

Functional Medicine says: This is anticipatory dopamine without executive function support. We optimize dopamine production, support prefrontal cortex function, and reduce overwhelm. Suddenly, you actually open the book.

10. Overcommitting Then Resenting Everyone

Functional Medicine says: This is attachment physiology + cortisol-driven people-pleasing. We regulate stress hormones, support boundaries through nervous system safety, and reduce inflammatory load. When your body feels safe, “no” becomes a complete sentence.

11. Cleaning Instead of Doing the One Thing

Functional Medicine says: This is safe dopamine seeking. We support dopamine pathways, reduce anxiety physiology, and stabilize the HPA axis. When your nervous system isn’t in threat mode, the “one thing” stops feeling like danger.

12. Googling Symptoms Until You Diagnose Yourself with Rare Diseases

Functional Medicine says: This is hypervigilance from inflammation + cortisol + gut-brain dysregulation. We repair the gut, reduce inflammatory cytokines, and calm the amygdala. When the body stops screaming, Google loses its power.

13. Starting 12 Projects and Finishing None

Functional Medicine says: This is dopamine-driven initiation + executive dysfunction from inflammation. We support mitochondrial output, reduce neuroinflammation, and stabilize dopamine. Suddenly finishing things feels possible, not punishing.

14. Taking Things Personally

Functional Medicine says: This is social threat hyperactivation, often from chronic stress, trauma-patterned wiring, or gut-driven inflammation. We regulate the nervous system, support oxytocin pathways, and reduce inflammatory load. When your physiology feels safe, you stop interpreting sighs as rejection.

15. Avoiding Rest Because You Don’t Feel Like You Deserve It

Functional Medicine says: This is stress chemistry addiction. We retrain the nervous system, stabilize cortisol, support parasympathetic tone, and rebuild safety around stillness. When your body trusts rest, you stop running on chaos chemistry.

And just like the cats, humans have their own crimes. Most never notice them. Most never question them. Most never realize their body has been confessing for years.

But if you felt something tug at you while reading this, a flicker of recognition, a pulse of curiosity, a quiet “oh… that’s me”

then you’re already standing at the threshold.

Some doors don’t open for everyone. But this one will open for you.
