Longevity mogul Bryan Johnson questions his extreme anti-aging experiments after illness diagnosis
Tech billionaire Bryan Johnson said on X that his pursuit of immortality may have gone too far after being diagnosed with autoimmune gastritis.
Bryan Johnson, a California-based tech millionaire and venture capitalist, used his X account to acknowledge that his quest to defeat aging may have been excessive after doctors identified autoimmune gastritis in his stomach lining. The revelation arrives just days after he announced a controversial plan to clone himself as an infant for organ harvesting, describing the idea as a "frontier of new paths" to reverse aging.
Johnson has invested roughly $10 million in various longevity projects, including intensive health monitoring, a strict supplement schedule, and periodic transfusions of his son Talmage’s blood plasma. His recent posts have sparked a mix of ridicule and alarm, especially after he previously shared intimate details about his family’s biology. This latest admission suggests a possible shift in his approach to extreme biohacking practices.
