For years, multi-millionaire Bryan Johnson has chased after immortality, embracing bizarre “anti-aging” procedures like hyperbaric oxygen therapy and huge numbers of supplements. Unsurprisingly, those woo-woo biohacks haven’t worked — Johnson was recently diagnosed with an incurable autoimmune disease, which is tough news for anybody, let alone someone convinced they can buy their way out of death itself.
