You ever feel like a glitch in the matrix? Maybe it’s that 3:00 AM panic about an email you forgot to send, or the way your heart hammers when you have to speak in a meeting. It’s weird. We live in a world of climate control, grocery deliveries, and high-speed internet, yet our bodies react like there's a leopard crouching in the cubicle next to us. Honestly, the reason is pretty simple: you weren't meant to be human—at least, not the kind of human the modern world expects you to be.
We’re basically running 50,000-year-old software on 2026 hardware. It’s a mess.
Evolution is slow. Like, painfully slow. While technology moves at the speed of light, our biology is still lagging in the Pleistocene. Biologists call this "evolutionary mismatch." It’s the idea that the environment we evolved in is so radically different from our current one that our natural instincts are now actively working against us. We aren't broken. We’re just out of place.
The Evolutionary Mismatch: Why Your Biology Feels Wrong
The phrase "you weren't meant to be human" in a modern context refers to this gap. For roughly 95% of human history, we were hunter-gatherers. We lived in small, tight-knit tribes of about 50 to 150 people. Life was dangerous, sure, but it was also incredibly straightforward. You found food, you avoided being eaten, and you hung out with people you’d known since birth.
Then, suddenly, we invented agriculture. Then cities. Then the industrial revolution. Then the smartphone.
In the blink of an evolutionary eye, we went from walking 12 miles a day to sitting in ergonomic chairs for ten hours. We went from seeing only the same 100 faces to being exposed to millions of people online. This creates a massive internal friction. Dr. Stephen Ilardi, a psychologist at the University of Kansas and author of The Depression Cure, argues that many of our modern mental health struggles are actually "diseases of civilization." Our bodies expect high activity, constant sunlight, and deep social integration. Instead, we get blue light and isolation.
The Cortisol Problem
Back on the savanna, stress was a survival tool. If a predator showed up, your HPA axis (hypothalamic-pituitary-adrenal) kicked in. It dumped cortisol and adrenaline into your system. You either fought or you ran. Once the threat was gone, the stress dissipated.

Today? The "predator" is a mortgage payment or a passive-aggressive Slack message. These aren't threats you can punch or run away from. So, the cortisol just sits there. It simmers. This chronic stress is a primary driver of systemic inflammation, which researchers like Dr. Gabor Maté have linked to everything from autoimmune disorders to heart disease. We aren't designed for "always-on" stress. We are designed for acute bursts of intensity followed by long periods of lounging.
We Weren't Meant to Be This Lonely
Loneliness is literally lethal. It’s not just a sad feeling; it’s a biological red alert. In our ancestral past, being alone meant certain death. If the tribe kicked you out, you were done for. No one to help you hunt, no one to watch your back while you slept.
This is why social rejection hurts so much. Neuroscientists at UCLA, including Naomi Eisenberger, have used fMRI scans to show that social rejection activates the same regions of the brain as physical pain—specifically the dorsal anterior cingulate cortex. When someone leaves you on "read" or you don't get invited to that dinner, your brain processes it as if someone just broke your arm.
The modern world is a loneliness factory.
We live in "nuclear" families, separated by drywall and fences. We’ve traded the "village" for the "feed." But the feed is a poor substitute. When you scroll through Instagram, you’re seeing a curated highlight reel of thousands of people. Your primitive brain doesn't understand "curation." It just thinks, Wow, everyone else is doing better than me. I am low-status. I am going to be kicked out of the tribe. This constant status anxiety is exhausting because, again, you weren't meant to be human in a world where you compare yourself to eight billion others.
The High-Calorie Trap
If you put a bowl of M&Ms in front of me, I’m going to eat them. All of them. Most people would.

This isn't a lack of willpower; it’s survival. For most of human history, sugar and fat were incredibly rare. If you found a beehive or a fatty carcass, the only logical move was to gorge yourself. You didn't know when your next meal was coming.
Today, we live in an "obesogenic" environment. We are surrounded by ultra-processed foods designed by literal scientists to hit our "bliss point"—the perfect ratio of salt, sugar, and fat that triggers a massive dopamine release. Our ancestors would have killed for a cheeseburger. We have them delivered to our doors in twenty minutes. Our biology hasn't caught up to the fact that calories are no longer scarce. We are biologically programmed to overeat because our genes still think we’re in a famine.
Movement as a Requirement, Not an Option
We treat exercise like a hobby. We say things like, "I'm going to start working out."
But movement isn't a leisure activity; it’s a biological requirement for brain health. Physical activity increases Brain-Derived Neurotrophic Factor (BDNF), often called "Miracle-Gro for the brain." In the wild, movement was always purposeful—you moved to find food or safety. Now, we have to invent reasons to move. This is why "sitting is the new smoking" isn't just a catchy headline. When we remain sedentary, our metabolic systems shut down, and our brain chemistry sours.
Sleep and the Industrial Clock
Before the lightbulb, humans slept with the sun. We had a "biphasic" sleep pattern—we’d sleep for a few hours, wake up for a bit of quiet reflection or intimacy, and then sleep again until dawn.
Now, we force ourselves into a rigid 9-to-5 schedule. We use caffeine to blunt the signal of adenosine (the chemical that makes us feel sleepy) and then use alcohol or pills to force ourselves down at night. We are the only species on Earth that deliberately deprives itself of sleep. Matthew Walker, a leading sleep scientist at UC Berkeley, points out that sleep deprivation decimate our immune system and our emotional regulation.

We are living in a permanent state of jet lag. The natural rhythms of our bodies—the circadian and ultradian rhythms—are constantly being disrupted by the blue light of our screens and the hum of our refrigerators.
Redefining What it Means to "Be Human"
So, what do we do? We can't go back to living in caves. (The Wi-Fi is terrible, for one).
The goal isn't to reject technology or modern medicine. The goal is to recognize the "mismatch" and build "human-shaped" lives within a digital world. It’s about understanding that your anxiety, your cravings, and your exhaustion aren't personal failings. They are predictable biological responses to an unnatural environment.
You weren't meant to be human in a cubicle. You weren't meant to be human in a high-rise with no green space. You were meant to be human in the woods, under the stars, surrounded by people who know your name and your stories.
Actionable Steps to Align With Your Biology
Since we can't delete the modern world, we have to hack it. We need to create "ancestral proxies"—modern habits that satisfy ancient needs.
- Prioritize "Non-Exercise Activity": Don't just hit the gym for an hour and sit for the other 23. Get a standing desk. Walk while you’re on the phone. Our ancestors didn't "work out," they just moved. All the time.
- The 10-Minute Morning Sun Rule: Within 30 minutes of waking up, get outside. Natural light (even on a cloudy day) hits the melanopsin cells in your eyes, which sets your circadian clock and triggers cortisol release to wake you up. This also ensures you’ll produce melatonin about 14 hours later.
- The "Rule of Three" for Socializing: Research suggests we need at least three "high-stakes" relationships—people who would help you move or take you to the hospital. Focus less on "networking" and more on deepening a few core bonds.
- Batch Your Digital Stress: Your brain isn't built to handle 100 notifications a day. Turn off all non-human notifications. If it’s not a text or a call from a real person, you don't need to see it immediately. Check your emails and news in two or three "batches" daily to allow your nervous system to downregulate.
- Eat One-Ingredient Foods: If a food has an ingredient list as long as a CVS receipt, your body won't know what to do with it. Sticking to whole foods—meat, vegetables, fruit, nuts—aligns with the nutritional profile our metabolisms evolved to process.
- Practice Active Rest: Scrolling TikTok is not rest; it’s "passive stimulation." True rest is something like a walk, a hot bath, or staring at a tree. Your brain needs the "Default Mode Network" to kick in so it can process information and regulate emotions.
The feeling of being "out of place" is actually a sign of health. It means your instincts are still intact. You are an ancient creature navigating a sci-fi world. Once you stop fighting your biology and start working with it, things get a whole lot easier. You stop blaming yourself for being "lazy" or "anxious" and start realizing you’re just a very sophisticated primate trying to make sense of a very strange time to be alive.
Focus on the basics: movement, sunlight, real food, and real people. Everything else is just noise.
