Key Takeaways
1. Dinosaur Age: Leverage Your Size and Unpredictability.
In the run for your life, its awe-inspiring, terrifying, stupefying size would be, in fact, your greatest advantage.
Understand predator limitations. Despite their fearsome appearance, giant predators like the Tyrannosaurus rex were surprisingly slow due to the "square-cube law." Their immense weight meant their leg bones would shatter under the stress of anything more than a brisk walk, limiting their top speed to around 12-13 miles per hour. This makes them slower than a well-conditioned human sprinter.
Optimal speed for predators. Research shows that animals designed for optimal speed typically weigh around 200 pounds. This means you should fear mid-sized dinosaurs most, as they combine speed with predatory power. Any dinosaur weighing over 6,000 pounds would likely be outrun by a fit human due to metabolic and mass limitations on acceleration.
Evasion tactics are key. If pursued by a faster dinosaur, do not run in a straight line. Studies of modern predator-prey chases show that prey animals often succeed by running unpredictably, changing course frequently without decelerating when far away, and rapidly decelerating and turning sharply when the predator is within a few strides. Your endurance is also a significant advantage in a prolonged chase.
2. Chicxulub Asteroid: Seek Deep Shelter, Prepare for Global Winter.
The day the Chicxulub asteroid slammed into what is now the small town on Mexico’s Yucatán Peninsula that bears its name is the most consequential moment in the history of life on our planet.
Immediate impact survival. Upon hearing the sonic boom of the Chicxulub asteroid impact, immediately seek high ground and underground shelter. The impact generated a massive blast wave, triggered continent-wide earthquakes, and created skyscraper-tall tsunamis that hit coastlines globally within hours. Glass-like tektites, some the size of school buses, rained down, causing global firestorms.
Long-term environmental collapse. The impact ejected 100 billion tons of sulfur and oil into the atmosphere. This led to torrents of acid rain and a persistent black soot layer that blocked 90% of sunlight for at least three years, dropping global temperatures by 50 degrees Fahrenheit. Most food chains collapsed, and evaporation ceased, turning much of the Earth into desert.
Apocalyptic oasis. To survive the prolonged freeze and drought, your best bet is a mountainous tropical island like Madagascar, India (then an island), or Indonesia. These areas received just enough sunlight and fresh water to sustain some life. You would need a deep cave for shelter from the initial heat and tektites, and at least six years of food and warmth.
3. Ice Age: Adapt to Extreme Cold, Hunt Mammoths in Groups.
You’ll shiver beneath the mile-high walls of ice. You’ll cower in front of the prowling leopards and stalking cheetahs. And then, a few hours after your arrival, you’ll feel the first pangs of hunger.
Harsh, unique climate. The Ice Age (specifically 25,000 years ago) presented a cold, arid environment with sunny days but little rain, thanks to massive glaciers. This created a "mammoth steppe" with fertile river valleys and polar desert-like plateaus. Familiar animals like bison and reindeer coexisted with unexpected predators like cheetahs and lions.
Sophisticated ancient humans. The Pavlovian culture, inhabiting eastern Europe, were modern Homo sapiens, renowned for their sophisticated clothing, artwork, and intricate ivory carvings. They were tall, wore parka-like furs, and burned bones for fuel due to scarce wood. They were also expert mammoth hunters, a necessity for survival in this protein and fat-demanding environment.
Group hunting mammoths. Mammoth hunting was a collective, dangerous endeavor. You'd need to craft a flint-tipped spear and an atlatl (spear-thrower) to achieve lethal velocity. The strategy involved isolating a weak mammoth and herding it into a natural trap, then facing it head-on in a group to launch spears. If charged, zigzagging and finding cover were crucial, as a single injury could be fatal.
4. Ancient Egypt: Master Pyramid Logistics, Prioritize Safety.
The Great Pyramid doesn’t stand testament to Egypt’s scientific or technological achievements, but it does testify to its remarkable bureaucratic ones.
Massive conscripted labor. Working on Khufu's Great Pyramid in 2550 BCE meant joining a workforce of conscripted farmers, not slaves, during the Nile's annual flood. This project was a national effort, requiring quarrying, hauling, and placing a 5,000-pound block every five minutes for 25 years. You'd sleep on the ground and eat a diet of catfish, goat stew, and beer.
Dangers of the job. The work was physically brutal, leading to arthritis, lost limbs, and an average worker lifespan of 35. Dangers included:
- Extreme heat (110 degrees Fahrenheit)
- Schistosomiasis from the Nile
- Falling from the 52-degree pyramid face
- Workplace accidents from multi-ton stones
- Rope breaks during hauling
Bureaucratic marvel. The pyramid's construction was a triumph of organization, not advanced technology. Egyptians used ropes, sleds, and water-lubricated ramps to drag stones up an 11% grade. The project required synchronizing a million subjects, managing a city of 30,000 workers, and a sophisticated tax system to requisition resources and labor. When hauling the 80-ton granite slab, avoid standing in front of the 343 pullers to prevent severe injury from a snapping rope.
5. Pompeii: Act Immediately, Run North from the Eruption.
Your situation seems challenging—but, surprisingly, it’s not hopeless!
Eruption stages and threats. Upon seeing the black cloud from Mount Vesuvius, understand the eruption's progression: initial ashfall, followed by deadly pyroclastic flows. While lava is generally slow-moving and escapable, pyroclastic flows are superheated, suffocating sandstorms moving at autobahn speeds, capable of vitrifying brains. You must leave before these flows begin.
Strategic escape route. Your best chance for survival is to run north towards Naples, rather than south or attempting to escape by sea. The road to Naples was well-maintained, and historical accounts suggest most successful escapees fled in this direction. Running north also takes you away from the prevailing winds that would continuously rain ash and pumice if you went south.
Move quickly through Herculaneum. The small resort town of Herculaneum, just four miles from the vent, was engulfed by the first pyroclastic surge. To avoid a similar fate, you must pass through Herculaneum and reach the outskirts of Naples (a total of 13 miles from Pompeii) within four hours. Maintain a fast walk or jog, avoid lingering in tempting shelters, and prioritize hydration.
6. Medieval City Sieges: Preserve Knowledge, Fight Strategically.
The books of the Ancient Greeks sitting in Constantinople and moldering away in European monasteries contained philosophies and scientific discoveries of almost unimaginable genius, far more advanced than those of Europe’s scientists living more than a thousand years later.
Fleeing a sacked city. When a city is sacked, there is no distinction between citizens and soldiers; all are subject to torture, death, or enslavement. Running is imperative. In the Sack of Rome (410 CE), avoid wealthy districts like Palatine Hill, as Goths tortured the rich for treasure. Fleeing east towards the Metronia Gate offered a chance of escape, hoping the invaders were preoccupied with plunder.
Constantinople's formidable defense. In the 1453 siege of Constantinople, the city's Theodosian Walls were Europe's most formidable defensive structure, a triple-layered barrier. However, by 1453, the Byzantine Empire was a shadow of its former self, with only 7,000 defenders against 80,000 Ottomans. Avoid the weakest section, the Mesoteichion, where the Lycus River ran.
Strategic fighting and intellectual preservation. During the siege, Ottoman attacks were repelled for weeks by the defenders. If caught in the final assault, join tenacious groups like the Cretan warriors who barricaded themselves in towers, fighting for eight hours to secure safe passage. Crucially, before the final assault, salvage books from the Imperial Library of Constantinople, as these Ancient Greek texts contained revolutionary ideas that would spark the Renaissance in Western Europe.
7. Black Death & Dark Ages: Flee Cities, Prioritize Hygiene, Adapt to Famine.
In an absolutely staggering piece of bad luck, you have arrived on the eve of what is perhaps the greatest catastrophe to ever befall humankind: the Black Death.
Plague's devastating virulence. The Black Death (1348) was the world's first true pandemic, killing half the populations of China, the Middle East, North Africa, and Europe. Caused by Yersinia pestis, it spread via flea bites (bubonic plague) or person-to-person (pneumonic plague), with no known treatment. Symptoms included fever, headaches, and characteristic buboes, with a 60% fatality rate for bubonic and universal fatality for pneumonic.
Famine in the Dark Ages. The "Darkest Year" of 536 CE, caused by a series of massive volcanic eruptions, plunged the Northern Hemisphere into a decade-long cold and drought, leading to widespread famine. Cities became death traps as trade collapsed and food prices skyrocketed. Rural villages fared better, allowing for hunting, gathering, and planting cold-resistant crops like rye or barley.
Survival strategies. To survive these medieval crises:
- Flee cities: Rural areas offered better chances due to lower human density and opportunities for foraging.
- Prioritize hygiene: Bathe regularly and wear masks, especially around the sick, contrary to medieval medical advice.
- Avoid diseased food: Check grain for fungi like ergot, which caused excruciating pain and death.
- Adapt to economic shifts: After the Black Death, labor demand spiked, wages tripled, and serfdom declined, leading to mass prosperity for survivors.
8. Perilous Sea Voyages: Prepare for Disease, Mutiny, and Unforeseen Challenges.
Of the 260 sailors and five ships that departed Seville on Magellan’s great circumnavigation, only a single ship and eighteen sailors successfully returned.
Magellan's brutal circumnavigation. Magellan's 1519 voyage was fraught with peril:
- Mutiny: Spanish captains rebelled against Magellan's Portuguese leadership and dangerous routes.
- Starvation & Scurvy: A 7,000-mile miscalculation across the Pacific led to 98 days of eating rotting food, oxhides, and sawdust. Scurvy, caused by vitamin C deficiency, killed most sailors.
- Indigenous conflict: Magellan's imperialistic zeal led to his death in the Philippines.
- Enrique's revenge: Magellan's freed slave, Enrique, orchestrated a massacre of officers.
Blackbeard's pirate life. Sailing with Blackbeard (1717) offered lucrative opportunities but demanded adherence to strict pirate codes. Pirate ships were surprisingly democratic, with elected captains and shared loot, a response to the tyrannical merchant navy. However, dangers included:
- Disease: Unsanitary conditions, rotting food, and contaminated water.
- Violent punishments: Marooning for rule-breaking.
- Naval pursuit: The rise of the sugar trade made piracy too costly for European powers to ignore.
Survival lessons. Pack quince jam for vitamin C, understand the social dynamics of your crew, and know when to abandon a failing venture. For Blackbeard, this meant leaving his crew when the British Admiralty began actively hunting pirates, as the golden age of piracy was ending due to economic shifts.
9. Donner Party: Conserve Energy, Overcome Taboos for Survival.
The Donner Party might be infamous for its cannibalism, but more than a dozen members of the party opted to starve to death rather than eat the human dead.
Fatal miscalculations. The Donner Party's fate was sealed by choosing Lansford Hastings' "shortcut" in 1846, which added weeks to their journey and depleted supplies. Arriving late in the Sierra Nevada, they were trapped by early, heavy snows, just miles from the summit. Retreating to cabins condemned them to a winter of starvation.
Starvation and gender dynamics. In starvation situations, young, single men in peak physical shape die first due to higher metabolism and less fat reserves. Women, with more subcutaneous fat and lower metabolism, had a biological advantage. Conserving energy by doing nothing, rather than working or attempting arduous hikes, significantly increased survival chances.
Overcoming the cannibalism taboo. After weeks of starvation, the party resorted to cannibalism, a practice deeply taboo in Western culture but not innately revulsive. This taboo, traced to xenophobic Ancient Greek narratives, led many to starve rather than eat human flesh. To survive, one had to overcome this social norm, eating thoroughly cooked meat (avoiding the brain to prevent kuru) from the deceased.
10. 1906 Earthquake: Choose Sturdy Shelter, Navigate Post-Quake Chaos.
The earthquake exposes San Francisco’s history of corrupt politics and reckless construction like a scrupulous inspector.
Foreshock warning and immediate action. The 1906 San Francisco earthquake began with a 30-second foreshock, a critical window to seek shelter. Avoid streets due to falling debris from poorly constructed buildings, especially brick ones. Seek shelter in a single-story, multi-room, wood-frame house with a north-south orientation, hiding under a doorway or table.
Post-quake dangers. After the 60-second main shock, the city faced immediate threats:
- Gas explosions: Severed gas mains ignited, causing underground explosions and trenches.
- Firestorm: Over 50 fires erupted, exacerbated by burst water mains that left firefighters without water.
- Martial law: Brigadier General Frederick Funston illegally enacted martial law, ordering soldiers to shoot suspected looters, leading to numerous civilian deaths.
- Stampeding cattle: Escaped longhorn cattle trampled panicked residents.
Strategic evacuation. Evacuate by ferry from the Ferry Building, located at the end of Market Street. Walk deliberately, keep your hands empty to avoid being mistaken for a looter, and follow instructions from police or soldiers. If possible, join the naval firefighting efforts at the waterfront, which were the only successful ones in saving lives and property.
11. Titanic: Understand Ship Mechanics, Navigate Class, Survive Cold Water.
Remarkably, the Titanic’s deck never tilts beyond a few degrees, even as she takes on thousands of tons of water.
Slow, stable sinking. Despite hitting an iceberg, the Titanic sank slowly and stably over 2.5 hours, thanks to its state-of-the-art waterproof bulkheads. This stability, though ultimately insufficient to save the ship, allowed time for lifeboat launches and passenger evacuation, unlike most catastrophic shipwrecks of the era.
Navigating class barriers. As a third-class passenger, you faced significant obstacles:
- Locked access: Gates prevented lower-class passengers from reaching upper decks and lifeboats.
- Lack of information: No escape drills or clear signage.
- Discrimination: Lifeboats were preferentially loaded with women and children, especially on the port side.
To overcome this, dress in your finest clothes to blend in, and learn the ship's layout to find the unannounced escape routes, such as the stairwell to Scotland Road or the forward steerage ladders.
Cold water survival. If you can't get on a lifeboat, prepare for the 27-degree Fahrenheit water. Dress warmly, wear a life jacket, and slip into the water to avoid cold shock. Swim quickly (within 15 minutes) towards the nearest lifeboat, using stars for navigation, as your limbs will become incapacitated by the cold. Once aboard, avoid sudden movements to prevent cardiac arrest.
12. Worst Tornado: Seek Immediate, Multi-Layered Shelter.
The Tri-State Tornado holds every significant tornadic record that a twisted cloud could ever hope to accomplish.
Unprecedented meteorological anomaly. The Tri-State Tornado (1925) was a meteorological freak, the most powerful in recorded history. It traveled 219 miles across three states at an average of 59 mph, with winds exceeding 300 mph. Unlike typical tornadoes, it was often obscured by a sheath of heavy rain, appearing as a "black fog" and making it difficult to identify its true shape and path.
Tornado formation and speed. Tornadoes form from the collision of air masses with different temperatures and humidities, often in the Midwest's unobstructed flatlands. The Tri-State storm was fueled by a unique alignment of a supercell, dry line, and low-pressure system, moving in unison. It advanced at an astonishing 73 mph when it hit Gorham, Illinois, making escape by running or driving nearly impossible due to extreme headwinds.
Immediate, multi-layered shelter. Do not attempt to outrun or outdrive the tornado. Instead, seek immediate, multi-layered shelter. In Gorham, which suffered 100% destruction, run towards the oncoming tornado to Park Street, where some houses sustained less damage. Find the lowest, smallest interior room (closet, under stairs, bathtub) and use a large pot as a helmet to protect against flying debris. The primary danger is not the wind itself, but the projectiles it hurls.
