Johnson describes himself as a 'professional rejuvenation athlete' whose entire life is the experiment—discovery, analysis, and implementation all happening in one body. His job is to move from identifying an organ, to assessing therapy data, to incorporating a new pill, device, exercise, or meditation. He frames this as exactly what 2023 requires if you want to treat the body as a fully measurable, optimizable system.
