In the sun-drenched hills of Venice, California, Bryan Johnson is on a mission that sounds like a sci-fi plot: he’s trying to stop aging and potentially cheat death. The tech entrepreneur who sold his web payments company for $800 million has transformed his life into a meticulously controlled experiment of human optimization.

Johnson’s daily routine reads like a medical research protocol. He wakes before dawn, tracks every bodily function, and follows a rigorous health regimen that includes precise nutrition, targeted supplements, and exhaustive medical testing. His goal isn’t just personal health, he believes humanity stands at a critical technological crossroads where we might actually prevent biological aging.

What drives someone to such extremes? For Johnson, it’s a combination of technological possibility and philosophical conviction. He sees the emerging landscape of artificial intelligence as a potential gateway to extending human existence. His “Don’t Die” philosophy isn’t just a personal health kick, but a proposed global ideology that argues for human survival in an uncertain technological future.

Interestingly, Johnson is transparent about the potential psychological underpinnings of his approach. He acknowledges his past struggles with food control and views his current protocol as a systematic way of managing those impulses. His supplements company, Blueprint, emerged from his personal health journey, though he’s now considering selling or shutting it down to maintain the integrity of his broader mission.

While many might view his approach as eccentric, Johnson frames it as a rational response to unprecedented technological change. He’s not just selling a health protocol, he’s proposing a new way of thinking about human existence in an era of rapid technological transformation.

As AI continues to evolve at breakneck speed, Johnson believes we’re at a pivotal moment where our species’ survival isn’t guaranteed. His radical health optimization isn’t just about personal longevity, but about preparing humanity for an unknown technological future where our very existence might be at stake.
