What if the very thing we've spent centuries pursuing-comfort-is slowly killing us? Standing in a freezing Polish farmhouse, journalist Scott Carney watched six grown men hyperventilate until they nearly passed out, then march shirtless into subzero temperatures. He'd come to expose Wim Hof, the "Iceman" who claimed to control his immune system through breathing and cold exposure, as a fraud. Instead, Carney discovered something that would upend everything he believed about human biology: we've engineered ourselves into weakness. Our climate-controlled homes, sedentary lifestyles, and relentless pursuit of ease have created an epidemic of diseases our ancestors never faced-obesity, diabetes, autoimmune disorders. These aren't illnesses of deficiency but of excess, bodies attacking themselves because they've forgotten how to fight anything else. The caveman who chipped flint spears had your exact biology, yet would dominate you in any physical contest. What changed wasn't our genes-it was our environment. Think about jellyfish for a moment. They drift through oceans in perpetual comfort, expending minimal energy, responding only to the most basic survival needs. Sounds appealing, doesn't it? Our nervous systems certainly think so. We're hardwired for homeostasis-that sweet spot where temperature feels just right, hunger is satisfied, and effort is unnecessary. This isn't weakness; it's evolutionary efficiency. For 200,000 years, anatomically modern humans faced relentless environmental challenges with stone tools and animal skins. Comfort was rare, precious, and temporary. Then, around 1900, everything changed. Indoor plumbing arrived. Central heating. Refrigeration. Electric lighting. Suddenly, we could control our surroundings so completely that many of us live in perpetual spring-never too hot, never too cold, never truly hungry. We became the first species since jellyfish to almost completely bypass natural survival pressures.
