Bryan Johnson sold his payments company Braintree for $800 million, then dedicated his fortune to not dying. His Blueprint protocol represents the most extreme self-quantification experiment ever attempted: Johnson tracks hundreds of biomarkers and follows an algorithmically-optimized diet, supplement, and exercise regimen. Critics call it obsessive; Johnson calls it rational given the stakes. His biological age measurements suggest the protocol is working, though the approach requires resources and discipline beyond most people's reach. Johnson's real contribution may be cultural: by making longevity optimization visible and discussable, he normalizes the idea that aging is a problem to be solved rather than accepted. Blueprint has evolved into a company offering supplements and protocols to the public.
